2.1
Basic Connection Requirements
Getting
started
with
the
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 family of 16-bit
Digital Signal Controllers (DSC) requires attention
to a minimal set of device pin connections before
proceeding with development. The following is a list
of pin names, which must always be connected:
• All VDD and VSS pins
(see Section 2.2 “Decoupling Capacitors”)
• All AVDD and AVSS pins (regardless if ADC module
is not used)
(see Section 2.2 “Decoupling Capacitors”)
• VCAP
(see Section 2.3 “Capacitor on Internal Voltage
Regulator (VCAP)”)
• MCLR pin
(see Section 2.4 “Master Clear (MCLR) Pin”)
• PGECx/PGEDx pins used for In-Circuit Serial
Programming™ (ICSP™) and debugging purposes
(see Section 2.5 “ICSP Pins”)
• OSC1 and OSC2 pins when external oscillator
source is used
(see Section 2.6 “External Oscillator Pins”)
 2009-2012 Microchip Technology Inc.
2.2
Decoupling Capacitors
The use of decoupling capacitors on every pair of
power supply pins, such as VDD, VSS, AVDD, and
AVSS is required.
Consider the following criteria when using decoupling
capacitors:
• Value and type of capacitor: Recommendation of
0.1 µF (100 nF), 10-20V. This capacitor should be a
low-ESR and have resonance frequency in the
range of 20 MHz and higher. It is recommended that
ceramic capacitors be used.
• Placement on the printed circuit board: The
decoupling capacitors should be placed as close to
the pins as possible. It is recommended to place the
capacitors on the same side of the board as the
device. If space is constricted, the capacitor can be
placed on another layer on the PCB using a via;
however, ensure that the trace length from the pin to
the capacitor is within one-quarter inch (6 mm) in
length.
• Handling high-frequency noise: If the board is
experiencing high-frequency noise, upward of tens
of MHz, add a second ceramic-type capacitor in parallel to the above described decoupling capacitor.
The value of the second capacitor can be in the
range of 0.01 µF to 0.001 µF. Place this second
capacitor next to the primary decoupling capacitor.
In high-speed circuit designs, consider implementing a decade pair of capacitances as close to the
power and ground pins as possible. For example,
0.1 µF in parallel with 0.001 µF.
• Maximizing performance: On the board layout
from the power supply circuit, run the power and
return traces to the decoupling capacitors first, and
then to the device pins. This ensures that the
decoupling capacitors are first in the power chain.
Equally important is to keep the trace length
between the capacitor and the power pins to a
minimum, thereby reducing PCB track inductance.

Note
1:
As an option, instead of a hard-wired connection, an
inductor (L1) can be substituted between VDD and
AVDD to improve ADC noise rejection. The inductor
impedance should be less than 1 and the inductor
capacity greater than 10 mA.

Master Clear (MCLR) Pin
The MCLR pin provides for two specific device
functions:
MCLR
0.1 µF
Ceramic
The placement of this capacitor should be close to the
VCAP. It is recommended that the trace length not
exceed one-quarter inch (6 mm). Refer to Section 24.2
“On-Chip Voltage Regulator” for details.
(i.e., ADC conversion rate/2)
During device programming and debugging, the
resistance and capacitance that can be added to the
pin must be considered. Device programmers and
debuggers drive the MCLR pin. Consequently,
specific voltage levels (VIH and VIL) and fast signal
transitions must not be adversely affected. Therefore,
specific values of R and C will need to be adjusted
based on the application and PCB requirements.
For example, as shown in Figure 2-2, it is
recommended that the capacitor C, be isolated from
the MCLR pin during programming and debugging
operations.
Place the components shown in Figure 2-2 within
one-quarter inch (6 mm) from the MCLR pin.

TANK CAPACITORS
On boards with power traces running longer than six
inches in length, it is suggested to use a tank capacitor
for integrated circuits including DSCs to supply a local
power source. The value of the tank capacitor should
be determined based on the trace resistance that connects the power supply source to the device, and the
maximum current drawn by the device in the application. In other words, select the tank capacitor so that it
meets the acceptable voltage sag at the device. Typical
values range from 4.7 µF to 47 µF.

Note 1:
R  10 k is recommended. A suggested
starting value is 10 k. Ensure that the
MCLR pin VIH and VIL specifications are met.
2:
R1  470 will limit any current flowing into
MCLR from the external capacitor C, in the
event of MCLR pin breakdown, due to
Electrostatic Discharge (ESD) or Electrical
Overstress (EOS). Ensure that the MCLR pin
VIH and VIL specifications are met.
A low-ESR (< 0.5 Ohms) capacitor is required on the
VCAP pin, which is used to stabilize the voltage
regulator output voltage. The VCAP pin must not be
connected to VDD, and must have a minimum capacitor
22 µF, 16V connected to ground. The type can be
ceramic or tantalum. Refer to Section 27.0 “Electrical
Characteristics” for additional information.

2.5
ICSP Pins
The PGECx and PGEDx pins are used for In-Circuit
Serial Programming™ (ICSP™) and debugging purposes. It is recommended to keep the trace length
between the ICSP connector and the ICSP pins on the
device as short as possible. If the ICSP connector is
expected to experience an ESD event, a series resistor
is recommended, with the value in the range of a few
tens of Ohms, not to exceed 100 Ohms.
Pull-up resistors, series diodes, and capacitors on the
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger communications to the device. If such discrete components are
an application requirement, they should be removed
from the circuit during programming and debugging.
Alternatively, refer to the AC/DC characteristics and
timing requirements information in the respective
device Flash programming specification for information
on capacitive loading limits and pin input voltage high
(VIH) and input low (VIL) requirements.
Ensure that the “Communication Channel Select” (i.e.,
PGECx/PGEDx pins) programmed into the device
matches the physical connections for the ICSP to
MPLAB® ICD 3 or MPLAB REAL ICE™.
For more information on ICD 3 and REAL ICE
connection requirements, refer to the following
documents that are available on the Microchip web
site.
• “Using MPLAB® ICD 3” (poster) (DS51765)
• “MPLAB® ICD 3 Design Advisory” (DS51764)
• “MPLAB® REAL ICE™ In-Circuit Debugger
User’s Guide” (DS51616)
• “Using MPLAB® REAL ICE™” (poster) (DS51749)
2.6
External Oscillator Pins
Many DSCs have options for at least two oscillators: a
high-frequency primary oscillator and a low-frequency
secondary oscillator (refer to Section 9.0 “Oscillator
Configuration” for details).
The oscillator circuit should be placed on the same
side of the board as the device. Also, place the
oscillator circuit close to the respective oscillator pins,
not exceeding one-half inch (12 mm) distance
between them. The load capacitors should be placed
next to the oscillator itself, on the same side of the
board. Use a grounded copper pour around the
oscillator circuit to isolate them from surrounding
circuits. The grounded copper pour should be routed
directly to the MCU ground. Do not run any signal
traces or power traces inside the ground pour. Also, if
using a two-sided board, avoid any traces on the
other side of the board where the crystal is placed. A
suggested layout is shown in Figure 2-3.

2.7
Oscillator Value Conditions on
Device Start-up
If the PLL of the target device is enabled and
configured for the device start-up oscillator, the
maximum oscillator source frequency must be limited
to 4 MHz < FIN < 8 MHz to comply with device PLL
start-up conditions. This means that if the external
oscillator frequency is outside this range, the
application must start-up in the FRC mode first. The
default PLL settings after a POR with an oscillator
frequency outside this range will violate the device
operating speed.
Once the device powers up, the application firmware
can initialize the PLL SFRs, CLKDIV, and PLLDBF to a
suitable value, and then perform a clock switch to the
Oscillator + PLL clock source. Note that clock switching
must be enabled in the device Configuration Word.
2.8
Configuration of Analog and
Digital Pins During ICSP
Operations
If MPLAB ICD 3 or REAL ICE is selected as a
debugger, it automatically initializes all of the
Analog-to-Digital input pins (ANx) as “digital” pins, by
setting all bits in the ADPCFG and ADPCFG2 registers.
If your application needs to use certain analog-to-digital
pins as analog input pins during the debug session, the
user application must clear the corresponding bits in
the ADPCFG and ADPCFG2 registers during
initialization of the ADC module.
When MPLAB ICD 3 or REAL ICE is used as a
programmer, the user application firmware must
correctly configure the ADPCFG and ADPCFG2
registers. Automatic initialization of these registers is
only done during debugger operation. Failure to
correctly configure the register(s) will result in all
analog-to-digital pins being recognized as analog input
pins, resulting in the port value being read as a logic ‘0’,
which may affect user application functionality.
2.9
Unused I/Os
Unused I/O pins should be configured as outputs and
driven to a logic low state.
Alternatively, connect a 1k to 10k resistor between VSS
and unused pins and drive the output to logic low.
2.10
Typical Application Connection
Examples
Examples of typical application connections are shown
in Figure 2-4 through Figure 2-11.
The bits in the registers that correspond to the
analog-to-digital pins that are initialized by MPLAB ICD 2,
ICD 3, or REAL ICE, must not be cleared by the user
application firmware; otherwise, communication errors
will result between the debugger and the device.

CPU
Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610
families of devices. It is not intended to be
a comprehensive reference source. To
complement the information in this data
sheet, refer to Section 2. “CPU”
(DS70204) in the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 CPU module has a
16-bit (data) modified Harvard architecture with an
enhanced instruction set, including significant support
for DSP. The CPU has a 24-bit instruction word with a
variable length opcode field. The Program Counter
(PC) is 23 bits wide and addresses up to 4M x 24 bits
of user program memory space. The actual amount of
program memory implemented varies from device to
device. A single-cycle instruction prefetch mechanism
is used to help maintain throughput and provides predictable execution. All instructions execute in a single
cycle, with the exception of instructions that change the
program flow, the double-word move (MOV.D)
instruction and the table instructions. Overhead-free
program loop constructs are supported using the DO
and REPEAT instructions, both of which are
interruptible at any point.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices have sixteen, 16-bit working registers in the programmer’s
model. Each of the working registers can serve as a
data, address or address offset register. The sixteenth
working register (W15) operates as a Software Stack
Pointer (SP) for interrupts and calls.
There are two classes of instruction in the
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices: MCU and
DSP. These two instruction classes are seamlessly
integrated into a single CPU. The instruction set
includes many addressing modes and is designed for
optimum C compiler efficiency. For most instructions,
the
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 is capable of executing a data (or program data) memory read, a working register (data) read, a data memory write and a
program (instruction) memory read per instruction
cycle. As a result, three parameter instructions can be
supported, allowing A + B = C operations to be
executed in a single cycle.

model
for
the

and
dsPIC33FJ64GS406/606/608/610 is shown in
Figure 3-2.
3.1
Data Addressing Overview
The data space can be addressed as 32K words or
64 Kbytes and is split into two blocks, referred to as X
and Y data memory. Each memory block has its own
independent Address Generation Unit (AGU). The
MCU class of instructions operates solely through
the X memory AGU, which accesses the entire
memory map as one linear data space. Certain DSP
instructions operate through the X and Y AGUs to
support dual operand reads, which splits the data
address space into two parts. The X and Y data space
boundary is device-specific.
Overhead-free circular buffers (Modulo Addressing
mode) are supported in both X and Y address spaces.
The Modulo Addressing removes the software
boundary checking overhead for DSP algorithms.
Furthermore, the X AGU circular addressing can be
used with any of the MCU class of instructions. The X
AGU also supports Bit-Reversed Addressing to greatly
simplify input or output data reordering for radix-2 FFT
algorithms.
The upper 32 Kbytes of the data space memory map
can optionally be mapped into program space at any
16K program word boundary defined by the 8-bit
Program Space Visibility Page (PSVPAG) register. The
program-to-data space mapping feature lets any
instruction access program space as if it were data
space.
3.2
DSP Engine Overview
The DSP engine features a high-speed, 17-bit by 17-bit
multiplier, a 40-bit ALU, two 40-bit saturating
accumulators and a 40-bit bidirectional barrel shifter.
The barrel shifter is capable of shifting a 40-bit value up
to 16 bits, right or left, in a single cycle. The DSP
instructions operate seamlessly with all other
instructions and have been designed for optimal realtime performance. The MAC instruction and other associated instructions can concurrently fetch two data
operands from memory while multiplying two W
registers and accumulating and optionally saturating
the result in the same cycle. This instruction
functionality requires that the RAM data space be split
for these instructions and linear for all others. Data
space partitioning is achieved in a transparent and
flexible manner through dedicating certain working
registers to each address space.

Special MCU Features
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 supports 16/16
and 32/16 divide operations, both fractional and integer. All divide instructions are iterative operations. They
must be executed within a REPEAT loop, resulting in a
total execution time of 19 instruction cycles. The divide
operation can be interrupted during any of those
19 cycles without loss of data.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 features a 17-bit
by 17-bit single-cycle multiplier that is shared by both
the MCU ALU and DSP engine. The multiplier can perform signed, unsigned and mixed sign multiplication.
Using a 17-bit by 17-bit multiplier for 16-bit by 16-bit
multiplication not only allows you to perform mixed sign
multiplication, it also achieves accurate results for
special operations, such as (-1.0) x (-1.0).
FIGURE 3-1:
A 40-bit barrel shifter is used to perform up to a 16-bit
left or right shift in a single cycle. The barrel shifter can
be used by both MCU and DSP instructions.

3.5
Arithmetic Logic Unit (ALU)
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 ALU is 16 bits wide
and is capable of addition, subtraction, bit shifts and logic
operations. Unless otherwise mentioned, arithmetic
operations are 2’s complement in nature. Depending on
the operation, the ALU can affect the values of the Carry
(C), Zero (Z), Negative (N), Overflow (OV) and Digit Carry
(DC) Status bits in the SR register. The C and DC Status
bits operate as Borrow and Digit Borrow bits, respectively,
for subtraction operations.
The ALU can perform 8-bit or 16-bit operations,
depending on the mode of the instruction that is used.
Data for the ALU operation can come from the W
register array or data memory, depending on the
addressing mode of the instruction. Likewise, output
data from the ALU can be written to the W register array
or a data memory location.
Refer to the “16-bit MCU and DSC Programmer’s
_Reference Manual” (DS70157) for information on the
SR bits affected by each instruction.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 CPU incorporates
hardware support for both multiplication and division. This
includes a dedicated hardware multiplier and support
hardware for 16-bit divisor division.
3.5.1
MULTIPLIER
Using the high-speed, 17-bit x 17-bit multiplier of the
DSP engine, the ALU supports unsigned, signed or
mixed sign operation in several MCU multiplication
modes:
•
•

•
•
16-bit x 16-bit signed
16-bit x 16-bit unsigned
16-bit signed x 5-bit (literal) unsigned

16-bit unsigned x 5-bit (literal) unsigned
16-bit unsigned x 16-bit signed
8-bit unsigned x 8-bit unsigned
3.5.2
DIVIDER
The divide block supports 32-bit/16-bit and 16-bit/16-bit
signed and unsigned integer divide operations with the
following data sizes:
•
•
•
•
32-bit signed/16-bit signed divide
32-bit unsigned/16-bit unsigned divide
16-bit signed/16-bit signed divide
16-bit unsigned/16-bit unsigned divide
3.6
DSP Engine
The DSP engine consists of a high-speed, 17-bit x
17-bit multiplier, a barrel shifter and a 40-bit adder/
subtracter (with two target accumulators, round and
saturation logic).
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 is a single-cycle
instruction flow architecture; therefore, concurrent
operation of the DSP engine with MCU instruction flow
is not possible. However, some MCU ALU and DSP
engine resources can be used concurrently by the
same instruction (for example, ED, EDAC).
The DSP engine can also perform inherent
accumulator-to-accumulator operations that require no
additional data. These instructions are ADD, SUB and
NEG.
The DSP engine has options selected through bits in
the CPU Core Control register (CORCON), as listed
below:
•
•
•
•
•
•
Fractional or integer DSP multiply (IF)
Signed or unsigned DSP multiply (US)
Conventional or convergent rounding (RND)
Automatic saturation on/off for ACCA (SATA)
Automatic saturation on/off for ACCB (SATB)
Automatic saturation on/off for writes to data
memory (SATDW)
• Accumulator Saturation mode selection
(ACCSAT)

The quotient for all divide instructions ends up in W0 and
the remainder in W1. 16-bit signed and unsigned DIV
instructions can specify any W register for both the 16-bit
divisor (Wn) and any W register (aligned) pair
(W(m + 1):Wm) for the 32-bit dividend. The divide
algorithm takes one cycle per bit of divisor, so both 32-bit/
16-bit and 16-bit/16-bit instructions take the same
number of cycles to execute.

3.6.1
MULTIPLIER
The 17-bit x 17-bit multiplier is capable of signed or
unsigned operation and can multiplex its output using a
scaler to support either 1.31 fractional (Q31) or 32-bit
integer results. Unsigned operands are zero-extended
into the 17th bit of the multiplier input value. Signed
operands are sign-extended into the 17th bit of the
multiplier input value. The output of the 17-bit x 17-bit
multiplier/scaler is a 33-bit value that is sign-extended
to 40 bits. Integer data is inherently represented as a
signed 2’s complement value, where the Most
Significant bit (MSb) is defined as a sign bit. The range
of an N-bit 2’s complement integer is -2N-1 to 2N-1 – 1.
• For a 16-bit integer, the data range is -32768
(0x8000) to 32767 (0x7FFF) including 0.
• For a 32-bit integer, the data range is
-2,147,483,648 (0x8000 0000) to 2,147,483,647
(0x7FFF FFFF).
When the multiplier is configured for fractional
multiplication, the data is represented as a 2’s
complement fraction, where the MSb is defined as a
sign bit and the radix point is implied to lie just after the
sign bit (QX format). The range of an N-bit 2’s
complement fraction with this implied radix point is -1.0
to (1 – 21-N). For a 16-bit fraction, the Q15 data range
is -1.0 (0x8000) to 0.999969482 (0x7FFF) including 0
and has a precision of 3.01518x10-5. In Fractional
mode, the 16 x 16 multiply operation generates a
1.31 product that has a precision of 4.65661 x 10-10.
The same multiplier is used to support the MCU
multiply instructions, which include integer 16-bit
signed, unsigned and mixed sign multiply operations.
The MUL instruction can be directed to use byte or
word-sized operands. Byte operands will direct a 16-bit
result, and word operands will direct a 32-bit result to
the specified register(s) in the W array.
3.6.2
DATA ACCUMULATORS AND
ADDER/SUBTRACTER
The data accumulator consists of a 40-bit adder/
subtracter with automatic sign extension logic. It can
select one of two accumulators (A or B) as its preaccumulation
source
and
post-accumulation
destination. For the ADD and LAC instructions, the data
to be accumulated or loaded can be optionally scaled
using the barrel shifter prior to accumulation.
 2009-2012 Microchip Technology Inc.
3.6.2.1
Adder/Subtracter, Overflow and
Saturation
The adder/subtracter is a 40-bit adder with an optional
zero input into one side, and either true or complement
data into the other input.
• In the case of addition, the Carry/Borrow input is
active-high and the other input is true data (not
complemented).
• In the case of subtraction, the Carry/Borrow input
is active-low and the other input is complemented.
The adder/subtracter generates Overflow Status bits,
SA/SB and OA/OB, which are latched and reflected in
the STATUS register:
• Overflow from bit 39: this is a catastrophic
overflow in which the sign of the accumulator is
destroyed.
• Overflow into guard bits, 32 through 39: this is a
recoverable overflow. This bit is set whenever all
the guard bits are not identical to each other.
The adder has an additional saturation block that
controls accumulator data saturation, if selected. It
uses the result of the adder, the Overflow Status bits
described
previously
and
the
SAT<A:B>
(CORCON<7:6>) and ACCSAT (CORCON<4>) mode
control bits to determine when and to what value to
saturate.
Six STATUS register bits support saturation and
overflow:
• OA: ACCA overflowed into guard bits
• OB: ACCB overflowed into guard bits
• SA: ACCA saturated (bit 31 overflow and
saturation)
or
ACCA overflowed into guard bits and saturated
(bit 39 overflow and saturation)
• SB: ACCB saturated (bit 31 overflow and
saturation)
or
ACCB overflowed into guard bits and saturated
(bit 39 overflow and saturation)
• OAB: Logical OR of OA and OB
• SAB: Logical OR of SA and SB
The OA and OB bits are modified each time data
passes through the adder/subtracter. When set, they
indicate that the most recent operation has overflowed
into the accumulator guard bits (bits 32 through 39).
The OA and OB bits can also optionally generate an
arithmetic warning trap when set and the corresponding Overflow Trap Flag Enable bits (OVATE, OVBTE) in
the INTCON1 register are set (refer to Section 7.0
“Interrupt Controller”). This allows the user application to take immediate action, for example, to correct
system gain.
DS70591E-page 41
dsPIC33FJ32GS406/606/608/610 and dsPIC33FJ64GS406/606/608/610
The SA and SB bits are modified each time data
passes through the adder/subtracter, but can only be
cleared by the user application. When set, they indicate
that the accumulator has overflowed its maximum
range (bit 31 for 32-bit saturation or bit 39 for 40-bit
saturation) and will be saturated (if saturation is
enabled). When saturation is not enabled, SA and SB
default to bit 39 overflow and thus, indicate that a catastrophic overflow has occurred. If the COVTE bit in the
INTCON1 register is set, SA and SB bits will generate
an arithmetic warning trap when saturation is disabled.
• W13, Register Direct:
The rounded contents of the non-target
accumulator are written into W13 as a
1.15 fraction.
• [W13] + = 2, Register Indirect with Post-Increment:
The rounded contents of the non-target
accumulator are written into the address pointed
to by W13 as a 1.15 fraction. W13 is then
incremented by 2 (for a word write).
The Overflow and Saturation Status bits can optionally
be viewed in the STATUS Register (SR) as the logical
OR of OA and OB (in bit OAB) and the logical OR of SA
and SB (in bit SAB). Programmers can check one bit in
the STATUS Register to determine if either
accumulator has overflowed, or one bit to determine if
either accumulator has saturated. This is useful for
complex number arithmetic, which typically uses both
accumulators.
The round logic is a combinational block that performs
a conventional (biased) or convergent (unbiased)
round function during an accumulator write (store). The
Round mode is determined by the state of the RND bit
in the CORCON register. It generates a 16-bit,
1.15 data value that is passed to the data space write
saturation logic. If rounding is not indicated by the
instruction, a truncated 1.15 data value is stored and
the least significant word is simply discarded.
The device supports three Saturation and Overflow
modes:
• Bit 39 Overflow and Saturation:
When bit 39 overflow and saturation occurs, the
saturation logic loads the maximally positive
9.31 (0x7FFFFFFFFF) or maximally negative
9.31 value (0x8000000000) into the target accumulator. The SA or SB bit is set and remains set until
cleared by the user application. This condition is
referred to as ‘super saturation’ and provides
protection against erroneous data or unexpected
algorithm problems (such as gain calculations).
• Bit 31 Overflow and Saturation:
When bit 31 overflow and saturation occurs, the
saturation logic then loads the maximally positive
1.31 value (0x007FFFFFFF) or maximally negative 1.31 value (0x0080000000) into the target
accumulator. The SA or SB bit is set and remains
set until cleared by the user application. When
this Saturation mode is in effect, the guard bits are
not used, so the OA, OB or OAB bits are never
set.
• Bit 39 Catastrophic Overflow:
The bit 39 Overflow Status bit from the adder is
used to set the SA or SB bit, which remains set
until cleared by the user application. No saturation
operation is performed, and the accumulator is
allowed to overflow, destroying its sign. If the
COVTE bit in the INTCON1 register is set, a
catastrophic overflow can initiate a trap exception.
3.6.3
ACCUMULATOR ‘WRITE BACK’
The MAC class of instructions (with the exception of
MPY, MPY.N, ED and EDAC) can optionally write a
rounded version of the high word (bits 31 through 16)
of the accumulator that is not targeted by the instruction
into data space memory. The write is performed across
the X bus into combined X and Y address space. The
following addressing modes are supported:
DS70591E-page 42
3.6.3.1
Round Logic
Conventional rounding zero-extends bit 15 of the accumulator and adds it to the ACCxH word (bits 16 through
31 of the accumulator).
• If the ACCxL word (bits 0 through 15 of the
accumulator) is between 0x8000 and 0xFFFF
(0x8000 included), ACCxH is incremented.
• If ACCxL is between 0x0000 and 0x7FFF, ACCxH
is left unchanged.
A consequence of this algorithm is that over a
succession of random rounding operations, the value
tends to be biased slightly positive.
Convergent (or unbiased) rounding operates in the
same manner as conventional rounding, except when
ACCxL equals 0x8000. In this case, the Least
Significant bit (bit 16 of the accumulator) of ACCxH is
examined:
• If it is ‘1’, ACCxH is incremented.
• If it is ‘0’, ACCxH is not modified.
Assuming that bit 16 is effectively random in nature,
this scheme removes any rounding bias that may
accumulate.
The SAC and SAC.R instructions store either a
truncated (SAC), or rounded (SAC.R) version of the
contents of the target accumulator to data memory via
the X bus, subject to data saturation (see
Section 3.6.3.2 “Data Space Write Saturation”). For
the MAC class of instructions, the accumulator writeback operation functions in the same manner,
addressing combined MCU (X and Y) data space
though the X bus. For this class of instructions, the data
is always subject to rounding.

3.6.3.2
Data Space Write Saturation
3.6.4
BARREL SHIFTER
In addition to adder/subtracter saturation, writes to data
space can also be saturated, but without affecting the
contents of the source accumulator. The data space
write saturation logic block accepts a 16-bit, 1.15
fractional value from the round logic block as its input,
together with overflow status from the original source
(accumulator) and the 16-bit round adder. These inputs
are combined and used to select the appropriate
1.15 fractional value as output to write to data space
memory.
The barrel shifter can perform up to 16-bit arithmetic or
logic right shifts, or up to 16-bit left shifts in a single
cycle. The source can be either of the two DSP
accumulators or the X bus (to support multi-bit shifts of
register or memory data).
If the SATDW bit in the CORCON register is set, data
(after rounding or truncation) is tested for overflow and
adjusted accordingly:
The barrel shifter is 40 bits wide, thereby obtaining a
40-bit result for DSP shift operations and a 16-bit result
for MCU shift operations. Data from the X bus is
presented to the barrel shifter between bit positions 16
and 31 for right shifts, and between bit positions 0 and
16 for left shifts.
• For input data greater than 0x007FFF, data
written to memory is forced to the maximum
positive 1.15 value, 0x7FFF.
• For input data less than 0xFF8000, data written to
memory is forced to the maximum negative
1.15 value, 0x8000.
The shifter requires a signed binary value to determine
both the magnitude (number of bits) and direction of the
shift operation. A positive value shifts the operand right.
A negative value shifts the operand left. A value of ‘0’
does not modify the operand.
The Most Significant bit of the source (bit 39) is used to
determine the sign of the operand being tested.
If the SATDW bit in the CORCON register is not set, the
input data is always passed through unmodified under
all conditions.

and
dsPIC33FJ64GS406/606/608/610 architecture features separate program and data memory spaces and
buses. This architecture also allows the direct access
to program memory from the data space during code
execution.
User Memory Space
FIGURE 4-1:
4.1
Program Address Space
The program address memory space is 4M instructions. The space is addressable by a 24-bit value
derived either from the 23-bit Program Counter (PC)
during program execution, or from table operation or
data space remapping as described in Section 4.6
“Interfacing Program and Data Memory Spaces”.
User application access to the program memory space
is restricted to the lower half of the address range
(0x000000 to 0x7FFFFF). The exception is the use of
TBLRD/TBLWT operations, which use TBLPAG<7> to
permit access to the Configuration bits and Device ID
sections of the configuration memory space.
The memory maps are shown in Figure 4-1.

ORGANIZATION
4.1.2
All
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices reserve the
addresses between 0x00000 and 0x000200 for
hard-coded program execution vectors. A hardware
Reset vector is provided to redirect code execution from
the default value of the PC on device Reset to the actual
start of code. A GOTO instruction is programmed by the
user application at 0x000000, with the actual address for
the start of code at 0x000002.
The program memory space is organized in
word-addressable blocks. Although it is treated as
24 bits wide, it is more appropriate to think of each
address of the program memory as a lower and upper
word, with the upper byte of the upper word being
unimplemented. The lower word always has an even
address, while the upper word has an odd address (see
Figure 4-2).
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices also have
two Interrupt Vector Tables (IVT), located from
0x000004 to 0x0000FF and 0x000100 to 0x0001FF.
These vector tables allow each of the device interrupt
sources to be handled by separate Interrupt Service
Routines (ISRs). A more detailed discussion of the
Interrupt Vector Tables is provided in Section 7.1
“Interrupt Vector Table”.
Program memory addresses are always word-aligned
on the lower word, and addresses are incremented or
decremented by two during the code execution. This
arrangement provides compatibility with data memory
space addressing and makes data in the program
memory space accessible.

4.2
Data Address Space
The CPU has a separate 16-bit-wide data memory space.
The data space is accessed using separate Address
Generation Units (AGUs) for read and write operations.
The data memory maps is shown in Figure 4-3.
All Effective Addresses (EAs) in the data memory space
are 16 bits wide and point to bytes within the data space.
This arrangement gives a data space address range of
64 Kbytes or 32K words. The lower half of the data
memory space (that is, when EA<15> = 0) is used for
implemented memory addresses, while the upper half
(EA<15> = 1) is reserved for the Program Space
Visibility area (see Section 4.6.3 “Reading Data from
Program Memory Using Program Space Visibility”).
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices implement
up to 9 Kbytes of data memory. Should an EA point to
a location outside of this area, an all-zero word or byte
will be returned.
4.2.1
DATA SPACE WIDTH
The data memory space is organized in byte
addressable, 16-bit wide blocks. Data is aligned in data
memory and registers as 16-bit words, but all data
space EAs resolve to bytes. The Least Significant
Bytes (LSBs) of each word have even addresses, while
the Most Significant Bytes (MSBs) have odd
addresses.
4.2.2
DATA MEMORY ORGANIZATION
AND ALIGNMENT
To maintain backward compatibility with PIC® MCU
devices and improve data space memory usage
efficiency, the instruction set supports both word and
byte operations. As a consequence of byte accessibility, all Effective Address calculations are internally
scaled to step through word-aligned memory. For
example, the core recognizes that Post-Modified
Register Indirect Addressing mode [Ws++] that results
in a value of Ws + 1 for byte operations and Ws + 2 for
word operations.
Data byte reads will read the complete word that
contains the byte, using the LSB of any EA to
determine which byte to select. The selected byte is
placed onto the LSB of the data path. That is, data
memory and registers are organized as two parallel
byte-wide entities with shared (word) address decode
but separate write lines. Data byte writes only write to
the corresponding side of the array or register that
matches the byte address.
 2009-2012 Microchip Technology Inc.
All word accesses must be aligned to an even address.
Misaligned word data fetches are not supported, so
care must be taken when mixing byte and word
operations, or translating from 8-bit MCU code. If a
misaligned read or write is attempted, an address error
trap is generated. If the error occurred on a read, the
instruction underway is completed. If the error occurred
on a write, the instruction is executed but the write does
not occur. In either case, a trap is then executed,
allowing the system and/or user application to examine
the machine state prior to execution of the address
Fault.
All byte loads into any W register are loaded into the
Least Significant Byte. The Most Significant Byte is not
modified.
A Sign-Extend (SE) instruction is provided to allow user
applications to translate 8-bit signed data to 16-bit
signed values. Alternatively, for 16-bit unsigned data,
user applications can clear the MSB of any W register
by executing a Zero-Extend (ZE) instruction on the
appropriate address.
4.2.3
SFR SPACE
The first 2 Kbytes of the Near Data Space, from 0x0000
to 0x07FF, is primarily occupied by Special Function
Registers (SFRs). These are used by the core and
peripheral modules for controlling the operation of the
device.
SFRs are distributed among the modules that they
control, and are generally grouped together by module.
Much of the SFR space contains unused addresses;
these are read as ‘0’.
Note:
4.2.4
The actual set of peripheral features and
interrupts varies by the device. Refer to
the corresponding device tables and
pinout diagrams for device-specific
information.
NEAR DATA SPACE
The 8-Kbyte area between 0x0000 and 0x1FFF is
referred to as the Near Data Space. Locations in this
space are directly addressable via a 13-bit absolute
address field within all memory direct instructions.
Additionally, the whole data space is addressable using
MOV instructions, which support Memory Direct
Addressing mode with a 16-bit address field, or by
using Indirect Addressing mode using a working
register as an Address Pointer.

4.2.5
X AND Y DATA SPACES
The core has two data spaces, X and Y. These data
spaces can be considered either separate (for some
DSP instructions), or as one unified linear address
range (for MCU instructions). The data spaces are
accessed using two Address Generation Units (AGUs)
and separate data paths. This feature allows certain
instructions to concurrently fetch two words from RAM,
thereby enabling efficient execution of DSP algorithms
such as Finite Impulse Response (FIR) filtering and
Fast Fourier Transform (FFT).
The X data space is used by all instructions and
supports all addressing modes. X data space has
separate read and write data buses. The X read data
bus is the read data path for all instructions that view
data space as combined X and Y address space. It is
also the X data prefetch path for the dual operand DSP
instructions (MAC class).
The Y data space is used in concert with the X data
space by the MAC class of instructions (CLR, ED, EDAC,
MAC, MOVSAC, MPY, MPY.N and MSC) to provide two
concurrent data read paths.
Both the X and Y data spaces support Modulo
Addressing mode for all instructions, subject to
addressing mode restrictions. Bit-Reversed Addressing
mode is only supported for writes to X data space.
 2009-2012 Microchip Technology Inc.
All data memory writes, including in DSP instructions,
view data space as combined X and Y address space.
The boundary between the X and Y data spaces is
device-dependent and is not user-programmable.
All Effective Addresses (EAs) are 16 bits wide and point
to bytes within the data space. Therefore, the data
space address range is 64 Kbytes, or 32K words,
though the implemented memory locations vary by
device.
4.2.6
DMA RAM
Some devices contain 1 Kbyte of dual ported DMA
RAM, which is located at the end of Y data space.
Memory locations that are part of Y data RAM and are in
the DMA RAM space are accessible simultaneously by
the CPU and the DMA Controller module. DMA RAM is
utilized by the DMA Controller to store data to be
transferred to various peripherals using DMA, as well as
data transferred from various peripherals using DMA.
The DMA RAM can be accessed by the DMA Controller
without having to steal cycles from the CPU.
When the CPU and the DMA Controller attempt to
concurrently write to the same DMA RAM location, the
hardware ensures that the CPU is given precedence in
accessing the DMA RAM location. Therefore, the DMA
RAM provides a reliable means of transferring DMA
data without ever having to stall the CPU.

SOFTWARE STACK
In addition to its use as a working register, the W15
register in the dsPIC33FJ32GS406/606/608/610 and
dsPIC33FJ64GS406/606/608/610 devices is also used
as a Software Stack Pointer. The Stack Pointer always
points to the first available free word and grows from
lower to higher addresses. It predecrements for stack
pops and post-increments for stack pushes, as shown
in Figure 4-6. For a PC push during any CALL instruction, the MSb of the PC is zero-extended before the
push, ensuring that the MSb is always clear.
Note:
A PC push during exception processing
concatenates the SRL register to the MSb
of the PC prior to the push.
The Stack Pointer Limit register (SPLIM) associated
with the Stack Pointer sets an upper address boundary
for the stack. SPLIM is uninitialized at Reset. As is the
case for the Stack Pointer, SPLIM<0> is forced to ‘0’
because all stack operations must be word-aligned.
Whenever an EA is generated using W15 as a source
or destination pointer, the resulting address is
compared with the value in SPLIM. If the contents of
the Stack Pointer (W15) and the SPLIM register are
equal and a push operation is performed, a stack error
trap will not occur. The stack error trap will occur on a
subsequent push operation. For example, to cause a
stack error trap when the stack grows beyond address
0x1800 in RAM, initialize the SPLIM with the value,
0x17FE.
Similarly, a Stack Pointer underflow (stack error) trap is
generated when the Stack Pointer address is found to
be less than 0x0800. This prevents the stack from
interfering with the Special Function Register (SFR)
space.
A write to the SPLIM register should not be immediately
followed by an indirect read operation using W15.

Instruction Addressing Modes
The addressing modes shown in Table 4-66 form the
basis of the addressing modes optimized to support the
specific features of individual instructions. The
addressing modes provided in the MAC class of
instructions differ from those in the other instruction
types.
4.3.1
FILE REGISTER INSTRUCTIONS
Most file register instructions use a 13-bit address field
(f) to directly address data present in the first
8192 bytes of data memory (Near Data Space). Most
file register instructions employ a working register, W0,
which is denoted as WREG in these instructions. The
destination is typically either the same file register or
WREG (with the exception of the MUL instruction),
which writes the result to a register or register pair. The
MOV instruction allows additional flexibility and can
access the entire data space.
4.3.2
MCU INSTRUCTIONS
The three-operand MCU instructions are of the form:
Operand 3 = Operand 1 <function> Operand 2
where Operand 1 is always a working register (that is,
the addressing mode can only be register direct), which
is referred to as Wb. Operand 2 can be a W register,
fetched from data memory, or a 5-bit literal. The result
location can be either a W register or a data memory
location. The following addressing modes are
supported by MCU instructions:
•
•
•
•
•
Register Direct
Register Indirect
Register Indirect Post-Modified
Register Indirect Pre-Modified
5-Bit or 10-Bit Literal
Note:
Not all instructions support all the
addressing modes given above. Individual
instructions can support different subsets
of these addressing modes.

Description
The address of the file register is specified explicitly.

Register Indirect Pre-Modified
Wn is pre-modified (incremented or decremented) by a signed constant value
to form the EA.
Register Indirect with Register Offset The sum of Wn and Wb forms the EA.
(Register Indexed)
Register Indirect with Literal Offset
4.3.3
The sum of Wn and a literal forms the EA.
MOVE AND ACCUMULATOR
INSTRUCTIONS
Move instructions and the DSP accumulator class of
instructions provide a greater degree of addressing
flexibility than other instructions. In addition to the
addressing modes supported by most MCU
instructions, move and accumulator instructions also
support Register Indirect with Register Offset
Addressing mode, also referred to as Register Indexed
mode.
Note:
For the MOV instructions, the addressing
mode specified in the instruction can differ
for the source and destination EA.
However, the 4-bit Wb (Register Offset)
field is shared by both source and
destination (but typically only used by
one).
In summary, the following addressing modes are
supported by move and accumulator instructions:
•
•
•
•
•
•
•
•
Register Direct
Register Indirect
Register Indirect Post-modified
Register Indirect Pre-modified
Register Indirect with Register Offset (Indexed)

Note:
Not all instructions support all the
addressing modes given above. Individual
instructions may support different subsets
of these addressing modes.

4.3.4
MAC INSTRUCTIONS
The dual source operand DSP instructions (CLR, ED,
EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), also referred
to as MAC instructions, use a simplified set of addressing
modes to allow the user application to effectively
manipulate the Data Pointers through Register Indirect
tables.
The two-source operand, prefetch registers must be
members of the set: {W8, W9, W10, W11}. For data
reads, W8 and W9 are always directed to the X RAGU,
and W10 and W11 are always directed to the Y AGU.
The Effective Addresses generated (before and after
modification) must, therefore, be valid addresses within
X data space for W8 and W9 and Y data space for W10
and W11.
Note:
Register Indirect with Register Offset
Addressing mode is available only for W9
(in X space) and W11 (in Y space).
In summary, the following addressing modes are
supported by the MAC class of instructions:
•
•
•
•
•
Register Indirect
Register Indirect Post-Modified by 2
Register Indirect Post-Modified by 4
Register Indirect Post-Modified by 6
Register Indirect with Register Offset (Indexed)
4.3.5
OTHER INSTRUCTIONS
Besides the addressing modes outlined previously, some
instructions use literal constants of various sizes. For
example, BRA (branch) instructions use 16-bit signed
literals to specify the branch destination directly, whereas
the DISI instruction uses a 14-bit unsigned literal field. In
some instructions, such as ADD Acc, the source of an
operand or result is implied by the opcode itself. Certain
operations, such as NOP, do not have any operands.

4.4
Modulo Addressing
4.4.1
Modulo Addressing mode is a method used to provide
an automated means to support circular data buffers
using hardware. The objective is to remove the need
for software to perform data address boundary checks
when executing tightly looped code, as is typical in
many DSP algorithms.
Modulo Addressing can operate in either data or program
space (since the Data Pointer mechanism is essentially
the same for both). One circular buffer can be supported
in each of the X (which also provides the pointers into
program space) and Y data spaces. Modulo Addressing
can operate on any W Register Pointer. However, it is not
advisable to use W14 or W15 for Modulo Addressing
since these two registers are used as the Stack Frame
Pointer and Stack Pointer, respectively.
In general, any particular circular buffer can be
configured to operate in only one direction as there are
certain restrictions on the buffer start address (for incrementing buffers), or end address (for decrementing
buffers), based upon the direction of the buffer.
The only exception to the usage restrictions is for
buffers that have a power-of-two length. As these
buffers satisfy the start and end address criteria, they
can operate in a bidirectional mode (that is, address
boundary checks are performed on both the lower and
upper address boundaries).
START AND END ADDRESS
The Modulo Addressing scheme requires that a
starting and ending address be specified and loaded
into the 16-bit Modulo Buffer Address registers:
XMODSRT, XMODEND, YMODSRT and YMODEND
(see Table 4-1).
Note:
Y Space Modulo Addressing EA
calculations assume word-sized data
(LSb of every EA is always clear).
The length of a circular buffer is not directly specified. It
is determined by the difference between the
corresponding start and end addresses. The maximum
possible length of the circular buffer is 32K words
(64 Kbytes).
4.4.2
W ADDRESS REGISTER
SELECTION
The Modulo and Bit-Reversed Addressing Control
register, MODCON<15:0>, contains enable flags as
well as a W register field to specify the W Address
registers. The XWM and YWM fields select the
registers that will operate with Modulo Addressing:
• If XWM = 15, X RAGU and X WAGU Modulo
Addressing is disabled.
• If YWM = 15, Y AGU Modulo Addressing is disabled.
The X Address Space Pointer W register (XWM), to
which Modulo Addressing is to be applied, is stored in
MODCON<3:0> (see Table 4-1). Modulo Addressing is
enabled for X data space when XWM is set to any value
other than ‘15’ and the XMODEN bit is set at
MODCON<15>.
The Y Address Space Pointer W register (YWM) to
which Modulo Addressing is to be applied is stored in
MODCON<7:4>. Modulo Addressing is enabled for Y
data space when YWM is set to any value other than
‘15’ and the YMODEN bit is set at MODCON<14>.

4.4.3
MODULO ADDRESSING
APPLICABILITY
Modulo Addressing can be applied to the Effective
Address (EA) calculation associated with any W
register. Address boundaries check for addresses
equal to:
• Upper boundary addresses for incrementing buffers
• Lower boundary addresses for decrementing buffers
It is important to realize that the address boundaries
check for addresses less than or greater than the upper
(for incrementing buffers) and lower (for decrementing
buffers) boundary addresses (not just equal to).
Address changes can, therefore, jump beyond
boundaries and still be adjusted correctly.
Note:
4.5
The modulo corrected Effective Address is
written back to the register only when
Pre-Modify or Post-Modify Addressing
mode is used to compute the Effective
Address. When an address offset (such as
[W7 + W2]) is used, Modulo Addressing
correction is performed but the contents of
the register remain unchanged.
Bit-Reversed Addressing
Bit-Reversed Addressing mode is intended to simplify
data re-ordering for radix-2 FFT algorithms. It is
supported by the X AGU for data writes only.
The modifier, which can be a constant value or register
contents, is regarded as having its bit order reversed. The
address source and destination are kept in normal order.
Thus, the only operand requiring reversal is the modifier.
4.5.1
BIT-REVERSED ADDRESSING
IMPLEMENTATION
Bit-Reversed Addressing mode is enabled in any of
these situations:
• BWMx bits (W register selection) in the MODCON
register are any value other than ‘15’ (the stack
cannot be accessed using Bit-Reversed
Addressing)
• The BREN bit is set in the XBREV register
• The addressing mode used is Register Indirect
with Pre-Increment or Post-Increment
If the length of a bit-reversed buffer is M = 2N bytes,
the last ‘N’ bits of the data buffer start address must
be zeros.
XB<14:0> is the Bit-Reversed Addressing modifier, or
‘pivot point,’ which is typically a constant. In the case of
an FFT computation, its value is equal to half of the FFT
data buffer size.
Note:
All bit-reversed EA calculations assume
word-sized data (LSb of every EA is
always clear). The XB value is scaled
accordingly to generate compatible (byte)
addresses.
When enabled, Bit-Reversed Addressing is executed
only for Register Indirect with Pre-Increment or
Post-Increment Addressing and word-sized data
writes. It will not function for any other addressing
mode or for byte-sized data, and normal addresses are
generated instead. When Bit-Reversed Addressing is
active, the W Address Pointer is always added to the
address modifier (XB), and the offset associated with
the Register Indirect Addressing mode is ignored. In
addition, as word-sized data is a requirement, the LSb
of the EA is ignored (and always clear).
Note:
Modulo Addressing and Bit-Reversed
Addressing should not be enabled
together. If an application attempts to do
so, Bit-Reversed Addressing will assume
priority when active for the X WAGU and X
WAGU, and Modulo Addressing will be
disabled. However, Modulo Addressing will
continue to function in the X RAGU.
If Bit-Reversed Addressing has already been enabled
by setting the BREN (XBREV<15>) bit, a write to the
XBREV register should not be immediately followed by
an indirect read operation using the W register that has
been designated as the Bit-Reversed Pointer.

4.6
Interfacing Program and Data
Memory Spaces
4.6.1
Since the address ranges for the data and program
spaces are 16 and 24 bits, respectively, a method is
needed to create a 23-bit or 24-bit program address
from 16-bit data registers. The solution depends on the
interface method to be used.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 architecture uses
a 24-bit-wide program space and a 16-bit-wide data
space. The architecture is also a modified Harvard
scheme, meaning that data can also be present in the
program space. To use this data successfully, it must
be accessed in a way that preserves the alignment of
information in both spaces.
For table operations, the 8-bit Table Page register
(TBLPAG) is used to define a 32K word region within
the program space. This is concatenated with a 16-bit
EA to arrive at a full 24-bit program space address. In
this format, the Most Significant bit of TBLPAG is used
to determine if the operation occurs in the user memory
(TBLPAG<7> = 0) or the configuration memory
(TBLPAG<7> = 1).
Aside from normal execution, the dsPIC33FJ32GS406/
606/608/610 and dsPIC33FJ64GS406/606/608/610
architecture provides two methods by which program
space can be accessed during operation:
For remapping operations, the 8-bit Program Space
Visibility register (PSVPAG) is used to define a
16K word page in the program space. When the Most
Significant bit of the EA is ‘1’, PSVPAG is concatenated
with the lower 15 bits of the EA to form a 23-bit program
space address. Unlike table operations, this limits
remapping operations strictly to the user memory area.
• Using table instructions to access individual bytes
or words anywhere in the program space
• Remapping a portion of the program space into
the data space (Program Space Visibility)
Table instructions allow an application to read or write
to small areas of the program memory. This capability
makes the method ideal for accessing data tables that
need to be updated periodically. It also allows access
to all bytes of the program word. The remapping
method allows an application to access a large block of
data on a read-only basis, which is ideal for look-ups
from a large table of static data. The application can
only access the least significant word of the program
word.
TABLE 4-68:
Table 4-68 and Figure 4-9 show how the program EA is
created for table operations and remapping accesses
from the data EA. Here, P<23:0> refers to a program
space word and D<15:0> refers to a data space word.

DATA ACCESS FROM PROGRAM
MEMORY USING TABLE
INSTRUCTIONS
The TBLRDL and TBLWTL instructions offer a direct
method of reading or writing the lower word of any
address within the program space without going
through data space. The TBLRDH and TBLWTH
instructions are the only method to read or write the
upper 8 bits of a program space word as data.
The PC is incremented by two for each successive
24-bit program word. This allows program memory
addresses to directly map to data space addresses.
Program memory can thus be regarded as two
16-bit-wide word address spaces, residing side by side,
each with the same address range. TBLRDL and
TBLWTL access the space that contains the least
significant data word. TBLRDH and TBLWTH access the
space that contains the upper data byte.
Two table instructions are provided to move byte or
word-sized (16-bit) data to and from program space.
Both function as either byte or word operations.
• TBLRDL (Table Read Low):
- In Word mode, this instruction maps the
lower word of the program space location
(P<15:0>) to a data address (D<15:0>).
FIGURE 4-10:
- In Byte mode, either the upper or lower byte
of the lower program word is mapped to the
lower byte of a data address. The upper byte
is selected when Byte Select is ‘1’; the lower
byte is selected when it is ‘0’.
• TBLRDH (Table Read High):
- In Word mode, this instruction maps the entire
upper word of a program address (P<23:16>)
to a data address. Note that D<15:8>, the
‘phantom byte’, will always be ‘0’.
- In Byte mode, this instruction maps the upper
or lower byte of the program word to D<7:0>
of the data address, in the TBLRDL
instruction. The data is always ‘0’ when the
upper ‘phantom’ byte is selected (Byte
Select = 1).
Similarly, two table instructions, TBLWTH and TBLWTL,
are used to write individual bytes or words to a program
space address. The details of their operation are
explained in Section 5.0 “Flash Program Memory”.
For all table operations, the area of program memory
space to be accessed is determined by the Table Page
register (TBLPAG). TBLPAG covers the entire program
memory space of the device, including user and
configuration spaces. When TBLPAG<7> = 0, the table
page is located in the user memory space. When
TBLPAG<7> = 1, the page is located in configuration
space.

READING DATA FROM PROGRAM
MEMORY USING PROGRAM SPACE
VISIBILITY
The upper 32 Kbytes of data space may optionally be
mapped into any 16K word page of the program space.
This option provides transparent access to stored
constant data from the data space without the need to
use special instructions (such as TBLRDL/H).
Program space access through the data space occurs
if the Most Significant bit of the data space EA is ‘1’ and
program space visibility is enabled by setting the PSV
bit in the Core Control register (CORCON<2>). The
location of the program memory space to be mapped
into the data space is determined by the Program
Space Visibility Page register (PSVPAG). This 8-bit
register defines any one of 256 possible pages of
16K words in program space. In effect, PSVPAG
functions as the upper 8 bits of the program memory
address, with the 15 bits of the EA functioning as the
lower bits. By incrementing the PC by 2 for each
program memory word, the lower 15 bits of data space
addresses directly map to the lower 15 bits in the
corresponding program space addresses.
Data reads to this area add a cycle to the instruction
being executed, since two program memory fetches
are required.
Although each data space address 8000h and higher
maps directly into a corresponding program memory
address (see Figure 4-11), only the lower 16 bits of the
FIGURE 4-11:
24-bit program word are used to contain the data. The
upper 8 bits of any program space location used as
data should be programmed with ‘1111 1111’ or
‘0000 0000’ to force a NOP. This prevents possible
issues should the area of code ever be accidentally
executed.
Note:
PSV access is temporarily disabled during
Table Reads/Writes.
For operations that use PSV and are executed outside
a REPEAT loop, the MOV and MOV.D instructions require
one instruction cycle in addition to the specified
execution time. All other instructions require two
instruction cycles in addition to the specified execution
time.
For operations that use PSV and are executed inside a
REPEAT loop, these instances require two instruction
cycles in addition to the specified execution time of the
instruction:
• Execution in the first iteration
• Execution in the last iteration
• Execution prior to exiting the loop due to an
interrupt
• Execution upon re-entering the loop after an
interrupt is serviced
Any other iteration of the REPEAT loop will allow the
instruction using PSV to access data, to execute in a
single cycle.

PGED3), and three other lines for power (VDD), ground
(VSS) and Master Clear (MCLR). This allows customers
to manufacture boards with unprogrammed devices
and then program the Digital Signal Controller (DSC)
just before shipping the product. This also allows the
most recent firmware or a custom firmware to be
programmed.
Note 1: This data sheet summarizes the
features of the dsPIC33FJ32GS406/
606/608/610 and dsPIC33FJ64GS406/
606/608/610 families of devices. It is
not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 5. “Flash Programming”
(DS70191) in the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com).
RTSP is accomplished using TBLRD (Table Read) and
TBLWT (Table Write) instructions. With RTSP, the user
application can write program memory data, either in
blocks or ‘rows’ of 64 instructions (192 bytes) at a time,
or a single program memory word, and erase program
memory in blocks or ‘pages’ of 512 instructions
(1536 bytes) at a time.
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
5.1
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices contain
internal Flash program memory for storing and executing application code. The memory is readable, writable
and erasable during normal operation over the entire
VDD range.
Flash memory can be programmed in two ways:
• In-Circuit Serial Programming™ (ICSP™)
• Run-Time Self-Programming (RTSP)
ICSP allows a dsPIC33FJ32GS406/606/608/610 and
dsPIC33FJ64GS406/606/608/610 device to be serially
programmed while in the end application circuit. This is
done with two lines for programming clock and
programming data (one of the alternate programming
pin pairs: PGEC1/PGED1, PGEC2/PGED2 or PGEC3/
FIGURE 5-1:
Table Instructions and Flash
Programming
Regardless of the method used, all programming of
Flash memory is done with the Table Read and Table
Write instructions. These allow direct read and write
access to the program memory space from the data
memory while the device is in normal operating mode.
The 24-bit target address in the program memory is
formed using bits<7:0> of the TBLPAG register and the
Effective Address (EA) from a W register specified in
the table instruction, as shown in Figure 5-1.
The TBLRDL and the TBLWTL instructions are used to
read or write to bits<15:0> of program memory.
TBLRDL and TBLWTL can access program memory in
both Word and Byte modes.
The TBLRDH and TBLWTH instructions are used to read
or write to bits<23:16> of program memory. TBLRDH
and TBLWTH can also access program memory in Word
or Byte mode.

5.2
RTSP Operation
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 Flash program
memory array is organized into rows of 64 instructions or
192 bytes. RTSP allows the user application to erase a
page of memory, which consists of eight rows
(512 instructions) at a time, and to program one row or
one word at a time. Table 27-12 shows typical erase and
programming times. The 8-row erase pages and single
row write rows are edge-aligned from the beginning of
program memory, on boundaries of 1536 bytes and
192 bytes, respectively.
The program memory implements holding buffers that
can contain 64 instructions of programming data. Prior
to the actual programming operation, the write data
must be loaded into the buffers sequentially. The
instruction words loaded must always be from a group
of 64 boundary.
The basic sequence for RTSP programming is to set up
a Table Pointer, then do a series of TBLWT instructions
to load the buffers. Programming is performed by
setting the control bits in the NVMCON register. A total
of 64 TBLWTL and TBLWTH instructions are required
to load the instructions.
All of the Table Write operations are single-word writes
(two instruction cycles) because only the buffers are written. A programming cycle is required for programming
each row.
5.3
Programming Operations
A complete programming sequence is necessary for
programming or erasing the internal Flash in RTSP
mode. The processor stalls (waits) until the
programming operation is finished.
For example, if the device is operating at +125°C, the
FRC accuracy will be ±2%. If the TUN<5:0> bits (see
Register 9-4) are set to ‘b000000, the minimum row
write time is equal to Equation 5-2.
EQUATION 5-2:
TRW =
MINIMUM ROW WRITE
TIME
11064 Cycles
= 1.477 ms
7.37 MHz  (1 + 0.02)  (1 – 0.00375)
The maximum row write time is equal to Equation 5-3.
EQUATION 5-3:
TRW =
MAXIMUM ROW WRITE
TIME
11064 Cycles
= 1.537 ms
7.37 MHz  (1 – 0.02)  (1 – 0.00375)
Setting the WR bit (NVMCON<15>) starts the
operation, and the WR bit is automatically cleared
when the operation is finished.
5.4
Control Registers
Two SFRs are used to read and write the program
Flash memory: NVMCON and NVMKEY.
The NVMCON register (Register 5-1) controls which
blocks are to be erased, which memory type is to be
programmed and the start of the programming cycle.
NVMKEY is a write-only register that is used for write
protection. To start a programming or erase sequence,
the user application must consecutively write 0x55 and
0xAA to the NVMKEY register. Refer to Section 5.3
“Programming Operations” for further details.
The programming time depends on the FRC accuracy
(see Table 27-20) and the value of the FRC Oscillator
Tuning register (see Register 9-4). Use the following
formula to calculate the minimum and maximum values
for the Row Write Time, Page Erase Time and Word
Write Cycle Time parameters (see Table 27-12).

5.4.1
PROGRAMMING ALGORITHM FOR
FLASH PROGRAM MEMORY
4.
5.
One row of program Flash memory can be
programmed at a time. To achieve this, it is necessary
to erase the 8-row erase page that contains the desired
row. The general process is:
1.
2.
3.
Read eight rows of program memory
(512 instructions) and store in data RAM.
Update the program data in RAM with the
desired new data.
Erase the block (see Example 5-1):
a) Set the NVMOPx bits (NVMCON<3:0>) to
‘0010’ to configure for block erase. Set the
ERASE (NVMCON<6>) and WREN
(NVMCON<14>) bits.
b) Write the starting address of the page to be
erased into the TBLPAG and W registers.
c) Write 0x55 to NVMKEY.
d) Write 0xAA to NVMKEY.
e) Set the WR bit (NVMCON<15>). The erase
cycle begins and the CPU stalls for the
duration of the erase cycle. When the erase is
done, the WR bit is cleared automatically.
EXAMPLE 5-1:
For protection against accidental operations, the write
initiate sequence for NVMKEY must be used to allow
any erase or program operation to proceed. After the
programming command has been executed, the user
application must wait for the programming time until
programming is complete. The two instructions
following the start of the programming sequence
should be NOPs, as shown in Example 5-3.

6.
Write the first 64 instructions from data RAM into
the program memory buffers (see Example 5-2).
Write the program block to Flash memory:
a) Set the NVMOPx bits to ‘0001’ to configure
for row programming. Clear the ERASE bit
and set the WREN bit.
b) Write 0x55 to NVMKEY.
c) Write 0xAA to NVMKEY.
d) Set the WR bit. The programming cycle
begins and the CPU stalls for the duration of
the write cycle. When the write to Flash
memory is done, the WR bit is cleared
automatically.
Repeat Steps 4 and 5, using the next available
64 instructions from the block in data RAM by
incrementing the value in TBLPAG, until all
512 instructions are written back to Flash memory.

RESETS
A simplified block diagram of the Reset module is
shown in Figure 6-1.
Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610
families of devices. It is not intended to be
a comprehensive reference source. To
complement the information in this data
sheet, refer to Section 8. “Reset”
(DS70192) in the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The Reset module combines all Reset sources and
controls the device Master Reset Signal, SYSRST. The
following is a list of device Reset sources:
•
•
•
•
•
•
•
POR: Power-on Reset
BOR: Brown-out Reset
MCLR: Master Clear Pin Reset
SWR: Software RESET Instruction
WDTO: Watchdog Timer Reset
TRAPR: Trap Conflict Reset
IOPUWR: Illegal Condition Device Reset
- Illegal Opcode Reset
- Uninitialized W Register Reset
- Security Reset
FIGURE 6-1:
Any active source of Reset will make the SYSRST
signal active. On system Reset, some of the registers
associated with the CPU and peripherals are forced to
a known Reset state and some are unaffected.
Note:
Refer to the specific peripheral section or
Section 3.0 “CPU” of this data sheet for
register Reset states.
All types of device Reset sets a corresponding status
bit in the RCON register to indicate the type of Reset
(see Register 6-1).
A POR clears all the bits, except for the POR bit
(RCON<0>), that are set. The user application can set
or clear any bit at any time during code execution. The
RCON bits only serve as status bits. Setting a particular
Reset status bit in software does not cause a device
Reset to occur.
The RCON register also has other bits associated with
the Watchdog Timer and device power-saving states.
The function of these bits is discussed in other sections
of this manual.
Note:
The status bits in the RCON register
should be cleared after they are read so
that the next RCON register value after a
device Reset is meaningful.

System Reset
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 families of devices
have two types of Reset:
• Cold Reset
• Warm Reset
A Cold Reset is the result of a Power-on Reset (POR)
or a Brown-out Reset (BOR). On a Cold Reset, the
FNOSCx Configuration bits in the FOSC Configuration
register select the device clock source.
TABLE 6-1:
A Warm Reset is the result of all the other Reset
sources, including the RESET instruction. On Warm
Reset, the device will continue to operate from the
current clock source as indicated by the Current
Oscillator Selection (COSC<2:0>) bits in the Oscillator
Control (OSCCON<14:12>) register.
The device is kept in a Reset state until the system
power supplies have stabilized at appropriate levels
and the oscillator clock is ready. The sequence in
which this occurs is described in Figure 6-2.

Note 1:
POR: A POR circuit holds the device in Reset when the power supply is turned on. The POR circuit is active until
VDD crosses the VPOR threshold and the delay, TPOR, has elapsed.
2:
BOR: The on-chip voltage regulator has a BOR circuit that keeps the device in Reset until VDD crosses the VBOR
threshold and the delay, TBOR, has elapsed. The delay, TBOR, ensures the voltage regulator output becomes
stable.
3:
PWRT Timer: The programmable Power-up Timer (PWRT) continues to hold the processor in Reset for a specific
period of time (TPWRT) after a BOR. The delay, TPWRT, ensures that the system power supplies have stabilized
at the appropriate level for full-speed operation. After the delay, TPWRT has elapsed and the SYSRST becomes
inactive, which in turn, enables the selected oscillator to start generating clock cycles.
4:
Oscillator Delay: The total delay for the clock to be ready for various clock source selections is given in
Table 6-1. Refer to Section 9.0 “Oscillator Configuration” for more information.
5:
When the oscillator clock is ready, the processor begins execution from location, 0x000000. The user application
programs a GOTO instruction at the Reset address, which redirects program execution to the appropriate start-up
routine.
6:
If the Fail-Safe Clock Monitor (FSCM) is enabled, it begins to monitor the system clock when the system clock is
ready and the delay, TFSCM, has elapsed.
Note:
When the device exits the Reset condition (begins normal operation), the device operating parameters
(voltage, frequency, temperature, etc.) must be within their operating ranges; otherwise, the device may
not function correctly. The user application must ensure that the delay between the time power is first
applied, and the time SYSRST becomes inactive, is long enough to get all operating parameters within
specification.

6.2
Power-on Reset (POR)
A Power-on Reset (POR) circuit ensures the device is
reset from power-on. The POR circuit is active until
VDD crosses the VPOR threshold and the delay, TPOR,
has elapsed. The delay, TPOR, ensures the internal
device bias circuits become stable.
The device supply voltage characteristics must meet
the specified starting voltage and rise rate
requirements to generate the POR. Refer to
Section 27.0 “Electrical Characteristics” for details.
The Power-on Reset (POR) status bit in the Reset
Control (RCON<0>) register is set to indicate the
Power-on Reset.
6.3
Brown-out Reset (BOR) and
Power-up Timer (PWRT)
The on-chip regulator has a Brown-out Reset (BOR)
circuit that resets the device when the VDD is too low
(VDD < VBOR) for proper device operation. The BOR
circuit keeps the device in Reset until VDD crosses the
FIGURE 6-3:
VBOR threshold and the delay, TBOR, has elapsed. The
delay, TBOR, ensures the voltage regulator output
becomes stable.
The Brown-out Reset (BOR) status bit in the Reset
Control (RCON<1>) register is set to indicate the
Brown-out Reset.
The device will not run at full speed after a BOR as the
VDD should rise to acceptable levels for full-speed
operation. The PWRT provides power-up time delay
(TPWRT) to ensure that the system power supplies have
stabilized at the appropriate levels for full-speed
operation before the SYSRST is released.
The Power-up Timer delay (TPWRT) is programmed by
the
Power-on
Reset
Timer
Value
Select
(FPWRT<2:0>) bits in the FPOR Configuration
(FPOR<2:0>) register, which provides eight settings
(from 0 ms to 128 ms). Refer to Section 24.0 “Special
Features” for further details.
Figure 6-3 shows the typical brown-out scenarios. The
Reset delay (TBOR + TPWRT) is initiated each time VDD
rises above the VBOR trip point

6.4
External Reset (EXTR)
The External Reset is generated by driving the MCLR
pin low. The MCLR pin is a Schmitt Trigger input with
an additional glitch filter. Reset pulses that are longer
than the minimum pulse width will generate a Reset.
Refer to Section 27.0 “Electrical Characteristics” for
minimum pulse width specifications. The External
Reset (MCLR) pin (EXTR) bit in the Reset Control
(RCON) register is set to indicate the MCLR Reset.
6.4.1
EXTERNAL SUPERVISORY
CIRCUIT
Many systems have external supervisory circuits that
generate Reset signals to reset multiple devices in the
system. This external Reset signal can be directly
connected to the MCLR pin to reset the device when
the rest of system is reset.
6.4.2
INTERNAL SUPERVISORY CIRCUIT
When using the internal power supervisory circuit to
reset the device, the External Reset pin (MCLR) should
be tied directly or resistively to VDD. In this case, the
MCLR pin will not be used to generate a Reset. The
External Reset pin (MCLR) does not have an internal
pull-up and must not be left unconnected.
6.7
Trap Conflict Reset
If a lower priority hard trap occurs while a higher
priority trap is being processed, a hard Trap Conflict
Reset occurs. The hard traps include exceptions of
Priority Level 13 through Level 15, inclusive. The
address error (Level 13) and oscillator error (Level 14)
traps fall into this category.
The Trap Reset (TRAPR) flag in the Reset Control
(RCON<15>) register is set to indicate the Trap Conflict
Reset. Refer to Section 7.0 “Interrupt Controller” for
more information on Trap Conflict Resets.
6.8
Illegal Condition Device Reset
An illegal condition device Reset occurs due to the
following sources:
• Illegal Opcode Reset
• Uninitialized W Register Reset
• Security Reset
The Illegal Opcode or Uninitialized W Access Reset
(IOPUWR) flag in the Reset Control (RCON<14>) register
is set to indicate the illegal condition device Reset.
6.8.1
ILLEGAL OPCODE RESET
Software RESET Instruction (SWR)
A device Reset is generated if the device attempts to
execute an illegal opcode value that is fetched from
program memory.
Whenever the RESET instruction is executed, the
device will assert SYSRST, placing the device in a
special Reset state. This Reset state will not
re-initialize the clock. The clock source in effect prior to
the RESET instruction will remain. SYSRST is released
at the next instruction cycle and the Reset vector fetch
will commence.
The Illegal Opcode Reset function can prevent the
device from executing program memory sections that
are used to store constant data. To take advantage of
the Illegal Opcode Reset, use only the lower 16 bits of
each program memory section to store the data values.
The upper 8 bits should be programmed with 3Fh,
which is an illegal opcode value.
The Software Reset (SWR) flag (instruction) in the
Reset Control (RCON<6>) register is set to indicate
the Software Reset.
6.8.2
6.5
6.6
Watchdog Timer Time-out Reset
(WDTO)
Whenever a Watchdog Timer Time-out Reset occurs,
the device will asynchronously assert SYSRST. The
clock source will remain unchanged. A WDT time-out
during Sleep or Idle mode will wake-up the processor,
but will not reset the processor.
The Watchdog Timer Time-out (WDTO) flag in the
Reset Control (RCON<4>) register is set to indicate
the Watchdog Timer Reset. Refer to Section 24.4
“Watchdog Timer (WDT)” for more information on
the Watchdog Timer Reset.
UNINITIALIZED W REGISTER RESET
Any attempt to use the uninitialized W register as an
Address Pointer will reset the device. The W register
array (with the exception of W15) is cleared during all
Resets and is considered uninitialized until written to.
6.8.3
SECURITY RESET
If a Program Flow Change (PFC) or Vector Flow
Change (VFC) targets a restricted location in a
protected segment (boot and secure segment), that
operation will cause a Security Reset.
The PFC occurs when the Program Counter is reloaded
as a result of a call, jump, computed jump, return, return
from subroutine or other form of branch instruction.
The VFC occurs when the Program Counter is
reloaded with an interrupt or trap vector.
Refer to Section 24.8 “Code Protection and
CodeGuard™ Security” for more information on
Security Reset.

Using the RCON Status Bits
The user application can read the Reset Control
(RCON) register after any device Reset to determine
the cause of the Reset.
Note:
Table 6-2 provides a summary of the Reset flag bit
operation.
The status bits in the RCON register

INTERRUPT CONTROLLER
Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610
families of devices. It is not intended to be
a comprehensive reference source. To
complement the information in this data
sheet, refer to Section 47. “Interrupts
(Part V)” (DS70597) in the “dsPIC33F/
PIC24H Family Reference Manual”,
which is available from the Microchip web
site (www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 interrupt controller
reduces the numerous peripheral interrupt request
signals to a single interrupt request signal to
the
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 CPU. It has the
following features:
• Up to Eight Processor Exceptions and Software
Traps
• Seven User-Selectable Priority Levels
• Interrupt Vector Table (IVT) with up to 118 Vectors
• A Unique Vector for each Interrupt or Exception
Source
• Fixed Priority within a Specified User Priority Level
• Alternate Interrupt Vector Table (AIVT) for Debug
Support
• Fixed Interrupt Entry and Return Latencies
7.1
Interrupt Vector Table
The Interrupt Vector Table (IVT) is shown in Figure 7-1.
The IVT resides in program memory, starting at location
000004h. The IVT contains 126 vectors, consisting of
eight nonmaskable trap vectors, plus up to 118 sources
of interrupt. In general, each interrupt source has its own
vector. Each interrupt vector contains a 24-bit-wide
address. The value programmed into each interrupt
vector location is the starting address of the associated
Interrupt Service Routine (ISR).
 2009-2012 Microchip Technology Inc.
Interrupt vectors are prioritized in terms of their natural
priority. This priority is linked to their position in the
vector table. Lower addresses generally have a higher
natural priority. For example, the interrupt associated
with Vector 0 will take priority over interrupts at any
other vector address.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices implement
up to 71 unique interrupts and five non-maskable traps.
These are summarized in Table 7-1.
7.1.1
ALTERNATE INTERRUPT VECTOR
TABLE
The Alternate Interrupt Vector Table (AIVT) is located
after the IVT, as shown in Figure 7-1. Access to the
AIVT is provided by the ALTIVT control bit
(INTCON2<15>). If the ALTIVT bit is set, all interrupt
and exception processes use the alternate vectors
instead of the default vectors. The alternate vectors are
organized in the same manner as the default vectors.
The AIVT supports debugging by providing a means to
switch between an application and a support environment without requiring the interrupt vectors to be
reprogrammed. This feature also enables switching
between applications for evaluation of different software algorithms at run time. If the AIVT is not needed,
the AIVT should be programmed with the same
addresses used in the IVT.
7.2
Reset Sequence
A device Reset is not a true exception because the
interrupt controller is not involved in the Reset process.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 device clears its
registers in response to a Reset, which forces the PC to
zero. The Digital Signal Controller (DSC) then begins
program execution at location, 0x000000. A GOTO
instruction at the Reset address can redirect program
execution to the appropriate start-up routine.
Note:
Any unimplemented or unused vector
locations in the IVT and AIVT should be
programmed with the address of a default
interrupt handler routine that contains a
RESET instruction.

Interrupt Control and Status
Registers
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices implement
44 registers for the interrupt controller:
•
•
•
•
•
•
INTCON1
INTCON2
IFSx
IECx
IPCx
INTTREG
7.3.1
INTCON1 AND INTCON2
Global interrupt control functions are controlled from
INTCON1 and INTCON2. INTCON1 contains the
Interrupt Nesting Disable (NSTDIS) bit as well as the
control and status flags for the processor trap sources.
The INTCON2 register controls the external interrupt
request signal behavior and the use of the Alternate
Interrupt Vector Table.
7.3.2
IFSx
The IFSx registers maintain all of the interrupt request
flags. Each source of interrupt has a status bit, which is
set by the respective peripherals or external signal and
is cleared via software.
7.3.3
IECx
The IECx registers maintain all of the interrupt enable
bits. These control bits are used to individually enable
interrupts from the peripherals or external signals.
7.3.4
IPCx
7.3.5
INTTREG
The INTTREG register contains the associated
interrupt vector number and the new CPU Interrupt
Priority Level, which are latched into the Vector Number (VECNUM<6:0>) and Interrupt Level (ILR<3:0>) bit
fields in the INTTREG register. The new Interrupt
Priority Level is the priority of the pending interrupt.
The interrupt sources are assigned to the IFSx, IECx
and IPCx registers in the same sequence that they are
listed in Table 7-1. For example, the INT0 (External
Interrupt 0) is shown as having vector number 8 and a
natural order priority of 0. Thus, the INT0IF bit is found
in IFS0<0>, the INT0IE bit is found in IEC0<0> and the
INT0IP bits are found in the first position of IPC0
(IPC0<2:0>).
7.3.6
STATUS/CONTROL REGISTERS
Although they are not specifically part of the interrupt
control hardware, two of the CPU Control registers
contain bits that control interrupt functionality.
• The CPU STATUS Register, SR, contains the
IPL<2:0> bits (SR<7:5>). These bits indicate the
current CPU Interrupt Priority Level. The user can
change the current CPU Priority Level by writing
to the IPL bits.
• The CORCON register contains the IPL3 bit,
which together with IPL<2:0>, indicates the
current CPU Priority Level. IPL3 is a read-only bit
so that trap events cannot be masked by the user
software.
All Interrupt registers are described in Register 7-1
through Register 7-46 in the following pages.
The IPCx registers are used to set the Interrupt Priority
Level for each source of interrupt. Each user interrupt
source can be assigned to one of eight priority levels.

The IPL<2:0> bits are concatenated with the IPL<3> bit (CORCON<3>) to form the CPU Interrupt Priority
Level. The value in parentheses indicates the IPL if IPL<3> = 1. User interrupts are disabled when
IPL<3> = 1.
The IPL<2:0> Status bits are read-only when NSTDIS (INTCON1<15>) = 1.

Interrupt Setup Procedures
7.4.1
7.4.3
INITIALIZATION
Complete the following steps to configure an interrupt
source at initialization:
1.
2.
Set the NSTDIS bit (INTCON1<15>) if nested
interrupts are not desired.
Select the user-assigned priority level for the
interrupt source by writing the control bits in the
appropriate IPCx register. The priority level will
depend on the specific application and type of
interrupt source. If multiple priority levels are not
desired, the IPCx register control bits for all
enabled interrupt sources can be programmed
to the same non-zero value.
Note:
3.
4.
At a device Reset, the IPCx registers are
initialized such that all user interrupt
sources are assigned to Priority Level 4.
Clear the interrupt flag status bit associated with
the peripheral in the associated IFSx register.
Enable the interrupt source by setting the
interrupt enable control bit associated with the
source in the appropriate IECx register.
7.4.2
TRAP SERVICE ROUTINE
A Trap Service Routine (TSR) is coded like an ISR,
except that the appropriate trap status flag in the
INTCON1 register must be cleared to avoid re-entry
into the TSR.
7.4.4
INTERRUPT DISABLE
The following steps outline the procedure to disable all
user interrupts:
1.
2.
Push the current SR value onto the software
stack using the PUSH instruction.
Force the CPU to Priority Level 7 by inclusive
ORing the value EOh with SRL.
To enable user interrupts, the POP instruction can be
used to restore the previous SR value.
Note:
Only user interrupts with a priority level of
7 or lower can be disabled. Trap sources
(Level 8-Level 15) cannot be disabled.
The DISI instruction provides a convenient way to
disable interrupts of Priority Levels 1-6 for a fixed
period of time. Level 7 interrupt sources are not
disabled by the DISI instruction.
INTERRUPT SERVICE ROUTINE
The method used to declare an ISR and initialize
IVT with the correct vector address depends on
programming language (C or assembler) and
language development toolsuite used to develop
application.
the
the
the
the
In general, the user application must clear the interrupt
flag in the appropriate IFSx register for the source of
interrupt that the ISR handles. Otherwise, program will
re-enter the ISR immediately after exiting the routine. If
the ISR is coded in assembly language, it must be
terminated using a RETFIE instruction to unstack the
saved PC value, SRL value and old CPU priority level.

DIRECT MEMORY ACCESS
(DMA)
Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610
family of devices. However, it is not
intended to be a comprehensive reference
source. To complement the information in
this data sheet, refer to Section 22.
“Direct Memory Access (DMA)”
(DS70182) in the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
TABLE 8-1:
Direct Memory Access (DMA) is a very efficient
mechanism of copying data between peripheral SFRs
(e.g., the UART Receive register and Input Capture 1
buffer) and buffers or variables stored in RAM, with
minimal CPU intervention. The DMA Controller
(DMAC) can automatically copy entire blocks of data
without requiring the user software to read or write the
peripheral Special Function Registers (SFRs) every
time a peripheral interrupt occurs. The DMA Controller
uses a dedicated bus for data transfers and, therefore,
does not steal cycles from the code execution flow of
the CPU. To exploit the DMA capability, the
corresponding user buffers or variables must be
located in DMA RAM.
Note:
The DMA module is not available on
dsIPC33FJ32GS406/606/608/610 and
dsPIC33FJ64GS406 devices.
The peripherals that can utilize DMA are listed in
Table 8-1 along with their associated Interrupt Request
(IRQ) numbers.

8.1
The DMA Controller features four identical data
transfer channels. Each channel has its own set of
control and status registers. Each DMA Channel can
be configured to copy data either from buffers stored in
dual port DMA RAM to peripheral SFRs or from
peripheral SFRs to buffers in DMA RAM.
DMAC Registers
Each DMAC Channel x (x = 0, 1, 2 or 3) contains the
following registers:
• A 16-Bit DMA Channel Control Register
(DMAxCON)
• A 16-Bit DMA Channel IRQ Select Register
(DMAxREQ)
• A 16-Bit DMA RAM Primary Start Address Offset
Register (DMAxSTA)
• A 16-Bit DMA RAM Secondary Start Address
Offset Register (DMAxSTB)
• A 16-Bit DMA Peripheral Address Register
(DMAxPAD)
• A 10-Bit DMA Transfer Count Register (DMAxCNT)
The DMA Controller supports the following features:
• Word or byte-sized data transfers.
• Transfers from peripheral to DMA RAM or DMA
RAM to peripheral
• Indirect Addressing of DMA RAM locations with or
without automatic post-increment
• Peripheral Indirect Addressing – In some
peripherals, the DMA RAM read/write addresses
may be partially derived from the peripheral
• One-Shot Block Transfers – Terminating DMA
transfer after one block transfer
• Continuous Block Transfers – Reloading DMA
RAM buffer start address after every block
transfer is complete
• Ping-Pong Mode – Switching between two DMA
RAM start addresses between successive block
transfers, thereby filling two buffers alternately
• Automatic or manual initiation of block transfers
An additional pair of status registers, DMACS0 and
DMACS1, are common to all DMAC channels.
For each DMA Channel, a DMA interrupt request is
generated when a block transfer is complete.
Alternatively, an interrupt can be generated when half of
the block has been filled.

CPU Clocking System
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices provide six
system clock options:
•
•
•
•
•
•
•
Fast RC (FRC) Oscillator
FRC Oscillator with PLL
Primary (XT, HS, or EC) Oscillator
Primary Oscillator with PLL
Low-Power RC (LPRC) Oscillator
FRC Oscillator with Postscaler
Secondary (LP) Oscillator
9.1.1
The FRC frequency depends on the FRC accuracy
(see Table 27-20) and the value of the FRC Oscillator
Tuning register (see Register 9-4).
9.1.2
SYSTEM CLOCK SOURCES
The Fast RC (FRC) internal oscillator runs at a nominal
frequency of 7.37 MHz. User software can tune the
FRC frequency. User software can optionally specify a
factor (ranging from 1:2 to 1:256) by which the FRC
clock frequency is divided. This factor is selected using
the FRCDIV<2:0> (CLKDIV<10:8>) bits.
The primary oscillator can use one of the following as
its clock source:
• XT (Crystal): Crystals and ceramic resonators in
the range of 3 MHz to 10 MHz. The crystal is
connected to the OSC1 and OSC2 pins
• HS (High-Speed Crystal): Crystals in the range of
10 MHz to 50 MHz. The crystal is connected to
the OSC1 and OSC2 pins
• EC (External Clock): The external clock signal is
directly applied to the OSC1 pin
SYSTEM CLOCK SELECTION
The oscillator source used at a device Power-on
Reset event is selected using Configuration bit
settings. The Oscillator Configuration bit settings are
located in the Configuration registers in the program
memory. (Refer to Section 24.1 “Configuration Bits”
for further details.) The Initial Oscillator Selection Configuration bits, FNOSC<2:0> (FOSCSEL<2:0>), and
the Primary Oscillator Mode Select Configuration bits,
POSCMD<1:0> (FOSC<1:0>), select the oscillator
source that is used at a Power-on Reset. The FRC
primary oscillator is the default (unprogrammed)
selection.
The Configuration bits allow users to choose among
12 different clock modes, shown in Table 9-1.
The output of the oscillator (or the output of the PLL if
a PLL mode has been selected), FOSC, is divided by 2
to generate the device instruction clock (FCY) and the
peripheral clock time base (FP). FCY defines the
operating speed of the device and speeds up to
50 MIPS are supported by the device architecture.
The secondary (LP) oscillator is designed for low power
and uses a 32.768 kHz crystal or ceramic resonator.
The LP oscillator uses the SOSCI and SOSCO pins.
The LPRC internal oscIllator runs at a nominal
frequency of 32.768 kHz. It is also used as a reference
clock by the Watchdog Timer (WDT) and Fail-Safe
Clock Monitor (FSCM).
TABLE 9-1:
The clock signals generated by the FRC and primary
oscillators can be optionally applied to an on-chip
Phase-Locked Loop (PLL) to provide a wide range of
output frequencies for device operation. PLL
configuration is described in Section 9.1.3 “PLL
Configuration”.
Instruction execution speed or device operating
frequency, FCY, is given by Equation 9-1.

9.1.3
PLL CONFIGURATION
For a primary oscillator or FRC oscillator, output ‘FIN’,
the PLL output ‘FOSC’ is given by Equation 9-2.
The primary oscillator and internal FRC oscillator can
optionally use an on-chip PLL to obtain higher speeds
of operation. The PLL provides significant flexibility in
selecting the device operating speed. A block diagram
of the PLL is shown in Figure 9-2.
EQUATION 9-2:
FOSC = FIN *
The output of the primary oscillator or FRC, denoted as
‘FIN’, is divided down by a prescale factor (N1) of 2, 3,
... or 33 before being provided to the PLL’s Voltage
Controlled Oscillator (VCO). The input to the VCO must
be selected in the range of 0.8 MHz to 8 MHz. The
prescale factor ‘N1’ is selected using the
PLLPRE<4:0> bits (CLKDIV<4:0>).
( N1M* N2 )
For example, suppose a 10 MHz crystal is being used
with the selected oscillator mode of XT with PLL (see
Equation 9-3).
The PLL Feedback Divisor, selected using the
PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor, ‘M’,
by which the input to the VCO is multiplied. This factor
must be selected such that the resulting VCO output
frequency is in the range of 100 MHz to 200 MHz.
The VCO output is further divided by a postscale factor,
‘N2’. This factor is selected using the PLLPOST<1:0>
bits (CLKDIV<7:6>). ‘N2’ can be either 2, 4 or 8, and
must be selected such that the PLL output frequency
(FOSC) is in the range of 12.5 MHz to 100 MHz, which
generates device operating speeds of 6.25-50 MIPS.
FIGURE 9-2:
FOSC CALCULATION
• If PLLPRE<4:0> = 0000, then N1 = 2. This yields
a VCO input of 10/2 = 5 MHz, which is within the
acceptable range of 0.8-8 MHz.
• If PLLDIV<8:0> = 0x26, then M = 40. This yields a
VCO output of 5 x 40 = 200 MHz, which is within
the 100-200 MHz ranged needed.
• If PLLPOST<1:0> = 00, then N2 = 2. This provides a FOSC of 200/2 = 100 MHz. The resultant
device operating speed is 100/2 = 40 MIPS.

9.2
Auxiliary Clock Generation
The auxiliary clock generation is used for a peripherals
that need to operate at a frequency unrelated to the
system clock such as a PWM or ADC.
The primary oscillator and internal FRC oscillator
sources can be used with an auxiliary PLL to obtain the
auxiliary clock. The auxiliary PLL has a fixed 16x
multiplication factor.
9.3
Reference Clock Generation
The reference clock output logic provides the user with
the ability to output a clock signal based on the system
clock or the crystal oscillator on a device pin. The user
application can specify a wide range of clock scaling
prior to outputting the reference clock.
The auxiliary clock has the following configuration
restrictions:
• For proper PWM operation, auxiliary clock
generation must be configured for 120 MHz (see
Parameter OS56 in Table 27-18 in Section 27.0
“Electrical Characteristics”). If a slower frequency
is desired, the PWM Input Clock Prescaler (Divider)
Select bits (PCLKDIV<2:0>) should be used.
• To achieve 1.04 ns PWM resolution, the auxiliary
clock must use the 16x auxiliary PLL (APLL). All
other clock sources will have a minimum PWM
resolution of 8 ns.
• If the primary PLL is used as a source for the auxiliary clock, the primary PLL should be configured
up to a maximum operation of 30 MIPS or less.

Clock Switching Operation
Applications are free to switch among any of the four
clock sources (primary, LP, FRC and LPRC) under
software control at any time. To limit the possible side
effects of this flexibility, dsPIC33FJ32GS406/606/608/
610 and dsPIC33FJ64GS406/606/608/610 devices
have a safeguard lock built into the switch process.
Note:
9.5.1
Primary oscillator mode has three different
submodes (XT, HS and EC), which are
determined by the POSCMD<1:0> Configuration bits. While an application can
switch to and from primary oscillator
mode in software, it cannot switch among
the different primary submodes without
reprogramming the device.
2.
If a valid clock switch has been initiated, the LOCK
(OSCCON<5>) and the CF (OSCCON<3>) status
bits are cleared.
The new oscillator is turned on by the hardware if
it is not currently running. If a crystal oscillator
must be turned on, the hardware waits until the
Oscillator Start-up Timer (OST) expires. If the new
source is using the PLL, the hardware waits until a
PLL lock is detected (LOCK = 1).
The hardware waits for 10 clock cycles from the
new clock source and then performs the clock
switch.
The hardware clears the OSWEN bit to indicate a
successful clock transition. In addition, the NOSCx
bit values are transferred to the COSCx status bits.
The old clock source is turned off at this time, with
the exception of LPRC (if WDT or FSCM are
enabled) or LP (if LPOSCEN remains set).

ENABLING CLOCK SWITCHING
To enable clock switching, the FCKSM1 Configuration
bit in the Configuration register must be programmed to
‘0’. (Refer to Section 24.1 “Configuration Bits” for
further details.) If the FCKSM1 Configuration bit is
unprogrammed (‘1’), the clock switching function and
Fail-Safe Clock Monitor function are disabled. This is
the default setting.
Note 1: The processor continues to execute code
throughout the clock switching sequence.
Timing-sensitive code should not be
executed during this time.
2: Direct clock switches between any primary oscillator mode with PLL and
FRCPLL mode are not permitted. This
applies to clock switches in either direction. In these instances, the application
must switch to FRC mode as a transition
clock source between the two PLL modes.
3: Refer to Section 42. “Oscillator (Part IV)”
(DS70307) in the “dsPIC33F/PIC24H
Family Reference Manual” for details.
The NOSC control bits (OSCCON<10:8>) do not
control the clock selection when clock switching is
disabled. However, the COSC bits (OSCCON<14:12>)
reflect the clock source selected by the FNOSC
Configuration bits.
The OSWEN control bit (OSCCON<0>) has no effect
when clock switching is disabled. It is held at ‘0’ at all
times.
9.5.2
OSCILLATOR SWITCHING SEQUENCE
To perform a clock switch, the following basic sequence
is required:
1.
2.
3.
4.
5.
If desired, read the COSCx bits (OSCCON<14:12>)
to determine the current oscillator source.
Perform the unlock sequence to allow a write to
the OSCCON register high byte.
Write the appropriate value to the NOSCx control
bits (OSCCON<10:8>) for the new oscillator
source.
Perform the unlock sequence to allow a write to
the OSCCON register low byte.
Set the OSWEN bit (OSCCON<0>) to initiate the
oscillator switch.
Once the basic sequence is completed, the system
clock hardware responds automatically as follows:
1.
The clock switching hardware compares the
COSCx status bits with the new value of the
NOSCx control bits. If they are the same, the clock
switch is a redundant operation. In this case, the
OSWEN bit is cleared automatically and the clock
switch is aborted.

9.6
Fail-Safe Clock Monitor (FSCM)
The Fail-Safe Clock Monitor (FSCM) allows the device
to continue to operate even in the event of an oscillator
failure. The FSCM function is enabled by programming.
If the FSCM function is enabled, the LPRC internal
oscillator runs at all times (except during Sleep mode)
and is not subject to control by the Watchdog Timer.
In the event of an oscillator failure, the FSCM
generates a clock failure trap event and switches the
system clock over to the FRC oscillator. Then, the
application program can either attempt to restart the
oscillator or execute a controlled shutdown. The trap
can be treated as a Warm Reset by simply loading the
Reset address into the oscillator fail trap vector.
If the PLL multiplier is used to scale the system clock,
the internal FRC is also multiplied by the same factor
on clock failure. Essentially, the device switches to
FRC with PLL on a clock failure.

POWER-SAVING FEATURES
Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610
families of devices. It is not intended to be
a comprehensive reference source. To
complement the information in this data
sheet, refer to Section 9. “Watchdog
Timer and Power-Saving Modes”
(DS70196) in the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices provide
the ability to manage power consumption by selectively
managing clocking to the CPU and the peripherals. In
general, a lower clock frequency and a reduction in the
number of circuits being clocked constitutes lower
consumed power. Devices can manage power
consumption in four different ways:
•
•
•
•
Clock Frequency
Instruction-Based Sleep and Idle modes
Software Controlled Doze mode
Selective Peripheral Control in Software
Combinations of these methods can be used to
selectively tailor an application’s power consumption
while still maintaining critical application features, such
as timing-sensitive communications.
10.1
Clock Frequency and Clock
Switching
The devices allow a wide range of clock frequencies to
be selected under application control. If the system
clock configuration is not locked, users can choose
low-power or high-precision oscillators by simply
changing the NOSCx bits (OSCCON<10:8>). The
process of changing a system clock during operation,
as well as limitations to the process, are discussed in
more
detail
in
Section 9.0
“Oscillator
Configuration”.
EXAMPLE 10-1:
10.2
Instruction-Based Power-Saving
Modes
The devices have two special power-saving modes that
are entered through the execution of a special PWRSAV
instruction. Sleep mode stops clock operation and halts all
code execution. Idle mode halts the CPU and code
execution, but allows peripheral modules to continue
operation. The assembler syntax of the PWRSAV
instruction is shown in Example 10-1.
Note:
SLEEP_MODE and IDLE_MODE are
constants defined in the assembler
include file for the selected device.
Sleep and Idle modes can be exited as a result of an
enabled interrupt, WDT time-out or a device Reset. When
the device exits these modes, it is said to wake-up.
10.2.1
SLEEP MODE
The following occurs in Sleep mode:
• The system clock source is shut down. If an
on-chip oscillator is used, it is turned off.
• The device current consumption is reduced to a
minimum, provided that no I/O pin is sourcing
current.
• The Fail-Safe Clock Monitor does not operate,
since the system clock source is disabled.
• The LPRC clock continues to run in Sleep mode if
the WDT is enabled.
• The WDT, if enabled, is automatically cleared
prior to entering Sleep mode.
• Some device features or peripherals may continue
to operate. This includes the items such as the
input change notification on the I/O ports or
peripherals that use an external clock input.
• Any peripheral that requires the system clock
source for its operation is disabled.
The device will wake-up from Sleep mode on any of
these events:
• Any interrupt source that is individually enabled
• Any form of device Reset
• A WDT time-out
On wake-up from Sleep mode, the processor restarts
with the same clock source that was active when Sleep
mode was entered.

10.2.2
IDLE MODE
The following occur in Idle mode:
• The CPU stops executing instructions.
• The WDT is automatically cleared.
• The system clock source remains active. By
default, all peripheral modules continue to operate
normally from the system clock source, but can
also be selectively disabled (see Section 10.5
“Peripheral Module Disable”).
• If the WDT or FSCM is enabled, the LPRC also
remains active.
The device will wake-up from Idle mode on any of these
events:
• Any interrupt that is individually enabled
• Any device Reset
• A WDT time-out
On wake-up from Idle mode, the clock is reapplied to
the CPU and instruction execution will begin (2-4 clock
cycles later), starting with the instruction following the
PWRSAV instruction, or the first instruction in the ISR.
10.2.3
INTERRUPTS COINCIDENT WITH
POWER SAVE INSTRUCTIONS
Any interrupt that coincides with the execution of a
PWRSAV instruction is held off until entry into Sleep or
Idle mode has completed. The device then wakes up
from Sleep or Idle mode.
10.3
Doze Mode
The preferred strategies for reducing power
consumption are changing clock speed and invoking
one of the power-saving modes. In some circumstances,
this may not be practical. For example, it may be necessary for an application to maintain uninterrupted
synchronous communication, even while it is doing nothing else. Reducing system clock speed can introduce
communication errors, while using a power-saving mode
can stop communications completely.
Doze mode is a simple and effective alternative method
to reduce power consumption while the device is still
executing code. In this mode, the system clock
continues to operate from the same source and at the
same speed. Peripheral modules continue to be
clocked at the same speed, while the CPU clock speed
is reduced. Synchronization between the two clock
domains is maintained, allowing the peripherals to
access the SFRs while the CPU executes code at a
slower rate.
DS70591E-page 202
Doze mode is enabled by setting the DOZEN bit
(CLKDIV<11>). The ratio between peripheral and core
clock speed is determined by the DOZE<2:0> bits
(CLKDIV<14:12>). There are eight possible configurations, from 1:1 to 1:128, with 1:1 being the default
setting.
Programs can use Doze mode to selectively reduce
power consumption in event-driven applications. This
allows clock-sensitive functions, such as synchronous
communications, to continue without interruption while
the CPU idles, waiting for something to invoke an
interrupt routine. An automatic return to full-speed CPU
operation on interrupts can be enabled by setting the
ROI bit (CLKDIV<15>). By default, interrupt events
have no effect on Doze mode operation.
For example, suppose the device is operating at
20 MIPS and the CAN module has been configured for
500 kbps based on this device operating speed. If the
device is placed in Doze mode with a clock frequency
ratio of 1:4, the CAN module continues to communicate
at the required bit rate of 500 kbps, but the CPU now
starts executing instructions at a frequency of 5 MIPS.
10.4
PWM Power-Saving Features
Typically, many applications need either a highresolution duty cycle or phase offset (for fixed
frequency operation) or a high-resolution PWM period
for variable frequency modes of operation (such as
Resonant mode). Very few applications require both
high-resolution modes simultaneously.
The HRPDIS and the HRDDIS bits in the AUXCONx
registers permit the user to disable the circuitry associated with the high-resolution duty cycle and PWM
period to reduce the operating current of the device.
If the HRDDIS bit is set, the circuitry associated with
the high-resolution duty cycle, phase offset, and dead
time for the respective PWM generator is disabled. If
the HRPDIS bit is set, the circuitry associated with the
high-resolution PWM period for the respective PWM
generator is disabled.
When the HRPDIS bit is set, the smallest unit of
measure for the PWM period is 8.32 ns.
If the HRDDIS bit is set, the smallest unit of measure
for the PWM duty cycle, phase offset and dead time is
8.32 ns.

10.5
Peripheral Module Disable
The Peripheral Module Disable (PMD) registers
provide a method to disable a peripheral module by
stopping all clock sources supplied to that module.
When a peripheral is disabled using the appropriate
PMD control bit, the peripheral is in a minimum power
consumption state. The control and status registers
associated with the peripheral are also disabled, so
writes to those registers will have no effect and read
values will be invalid.
Note:
If a PMD bit is set, the corresponding
module is disabled after a delay of one
instruction cycle. Similarly, if a PMD bit is
cleared, the corresponding module is
enabled after a delay of one instruction
cycle (assuming the module control registers are already configured to enable
module operation).
A peripheral module is enabled only if both the
associated bit in the PMD register is cleared and the
peripheral is supported by the specific dsPIC® DSC
variant. If the peripheral is present in the device, it is
enabled in the PMD register by default.

I/O PORTS
Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610
families of devices. It is not intended to be
a comprehensive reference source. To
complement the information in this data
sheet, refer to Section 10. “I/O Ports”
(DS70193) in the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
All of the device pins (except VDD, VSS, MCLR and
OSC1/CLKI) are shared among the peripherals and the
parallel I/O ports. All I/O input ports feature Schmitt
Trigger inputs for improved noise immunity.
11.1
When a peripheral is enabled and the peripheral is
actively driving an associated pin, the use of the pin as
a general purpose output pin is disabled. The I/O pin
can be read, but the output driver for the parallel port bit
is disabled. If a peripheral is enabled, but the peripheral
is not actively driving a pin, that pin can be driven by a
port.
All port pins have three registers directly associated
with their operation as digital I/O. The Data Direction
register (TRISx) determines whether the pin is an input
or an output. If the data direction bit is ‘1’, then the pin
is an input. All port pins are defined as inputs after a
Reset. Reads from the latch (LATx) read the latch.
Writes to the latch write the latch. Reads from the port
(PORTx) read the port pins, while writes to the port pins
write the latch.
Any bit and its associated data and control registers
that are not valid for a particular device will be
disabled. That means the corresponding LATx and
TRISx registers and the port pin will read as zeros.
When a pin is shared with another peripheral or
function that is defined as an input only, it is
nevertheless regarded as a dedicated port because
there is no other competing source of outputs.
Parallel I/O (PIO) Ports
Generally a parallel I/O port that shares a pin with a
peripheral is subservient to the peripheral. The
peripheral’s output buffer data and control signals are
provided to a pair of multiplexers. The multiplexers
select whether the peripheral or the associated port
has ownership of the output data and control signals of
the I/O pin. The logic also prevents “loop through”, in
which a port’s digital output can drive the input of a
peripheral that shares the same pin. Figure 11-1 shows
how ports are shared with other peripherals and the
associated I/O pin to which they are connected.

11.2
Open-Drain Configuration
In addition to the PORT, LAT and TRIS registers for
data control, some digital-only port pins can also be
individually configured for either digital or open-drain
output. This is controlled by the Open-Drain Control
register, ODCx, associated with each port. Setting any
of the bits configures the corresponding pin to act as an
open-drain output.
The open-drain feature allows the generation of
outputs higher than VDD (for example, 5V) on any
desired 5V tolerant pins by using external pull-up
resistors. The maximum open-drain voltage allowed is
the same as the maximum VIH specification.
Refer to “Pin Diagrams” for the available pins and
their functionality.
11.3
Configuring Analog Port Pins
The ADPCFG and TRIS registers control the operation
of the analog-to-digital port pins. The port pins that are
to function as analog inputs must have their corresponding TRIS bit set (input). If the TRIS bit is cleared
(output), the digital output level (VOH or VOL) will be
converted.
The ADPCFG and ADPCFG2 registers have a default
value of 0x000; therefore, all pins that share ANx
functions are analog (not digital) by default.
When the PORT register is read, all pins configured as
analog input channels will read as cleared (a low level).
Pins configured as digital inputs will not convert an
analog input. Analog levels on any pin defined as a
digital input (including the ANx pins) can cause the
input buffer to consume current that exceeds the
device specifications.

11.4
I/O Port Write/Read Timing
One instruction cycle is required between a port direction
change or port write operation and a read operation of
the same port. Typically, this instruction would be a NOP.
An example is shown in Example 11-1.
11.5
Input Change Notification
The input change notification function of the I/O
ports allows the dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610 devices to generate interrupt requests to the processor in response to
a Change-of-State (COS) on selected input pins. This
feature can detect input Change-of-States even in
Sleep mode, when the clocks are disabled. Depending
on the device pin count, up to 30 external signals (CNx
pin) can be selected (enabled) for generating an
interrupt request on a Change-of-State.
Four control registers are associated with the CN
module. The CNEN1 and CNEN2 registers contain the
interrupt enable control bits for each of the CN input
pins. Setting any of these bits enables a CN interrupt
for the corresponding pins.
Each CN pin also has a weak pull-up connected to it.
The pull-ups act as a current source connected to the
pin, and eliminate the need for external resistors when
the push button or keypad devices are connected. The
pull-ups are enabled separately using the CNPU1 and
CNPU2 registers, which contain the control bits for
each of the CN pins. Setting any of the control bits
enables the weak pull-ups for the corresponding pins.
Note:
Pull-ups on change notification pins
should always be disabled when the port
pin is configured as a digital output.

TIMER1
The unique features of Timer1 allow it to be used for
Real-Time Clock (RTC) applications. A block diagram
of Timer1 is shown in Figure 12-1.
Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610
families of devices. It is not intended to be
a comprehensive reference source. To
complement the information in this data
sheet, refer to Section 11. “Timers”
(DS70205) in the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com).
The Timer1 module can operate in one of the following
modes:
•
•
•
•
In Timer and Gated Timer modes, the input clock is
derived from the internal instruction cycle clock (FCY).
In Synchronous and Asynchronous Counter modes,
the input clock is derived from the external clock input
at the T1CK pin.
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The Timer modes are determined by the following bits:
• Timer Clock Source Control bit: TCS (T1CON<1>)
• Timer Synchronization Control bit: TSYNC
(T1CON<2>)
• Timer Gate Control bit: TGATE (T1CON<6>)
The Timer1 module is a 16-bit timer, which can serve
as a time counter for the Real-Time Clock (RTC), or
operate as a free-running interval timer/counter.
The timer control bit settings for different operating
modes are given in the Table 12-1.
The Timer1 module has the following unique features
over other timers:
TABLE 12-1:
• Can be operated from the low-power 32.767 kHz
crystal oscillator available on the device
• Can be operated in Asynchronous Counter mode
from an external clock source.
• The external clock input (T1CK) can optionally be
synchronized to the internal device clock and the
clock synchronization is performed after the
prescaler.

The Timer2/3/4/5 modules can operate in one of the
following modes:
• Timer mode
• Gated Timer mode
• Synchronous Counter mode
In Timer and Gated Timer modes, the input clock is
derived from the internal instruction cycle clock (FCY).
In Synchronous Counter mode, the input clock is
derived from the external clock input at the TxCK pin.
When configured for 32-bit operation, only the Type B
Timerx Control (TxCON) register bits are required for
setup and control while the Type C Timer Control
register bits are ignored (except the TSIDL bit).
For interrupt control, the combined 32-bit timer uses
the interrupt enable, interrupt flag and interrupt priority
control bits of the Type C timer. The interrupt control
and status bits for the Type B timer are ignored
during 32-bit timer operation.
The timer modes are determined by the following bits:
The timers that can be combined to form a 32-bit timer
are listed in Table 13-2.
• TCS (TxCON<1>): Timer Clock Source Control bit
• TGATE (TxCON<6>): Timer Gate Control bit

32-Bit Operation
A 32-bit timer module can be formed by combining a
Type B and a Type C 16-bit timer module. For 32-bit
timer operation, the T32 control bit in the Type B Timer
Control (TxCON<3>) register must be set. The Type C
timer holds the most significant word (msw) and the
Type B timer holds the least significant word (lsw)
for 32-bit operation.

and bit information.
The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices support up
to two input capture channels.
The input capture module captures the 16-bit value of
the selected Time Base register when an event occurs
at the ICx pin. The events that cause a capture event
are listed below in three categories:
FIGURE 14-1:
• Simple Capture Event modes:
- Capture timer value on every falling edge of
input at ICx pin
- Capture timer value on every rising edge of
input at ICx pin
• Capture Timer Value on Every Edge (rising and
falling)
• Prescaler Capture Event modes:
- Capture timer value on every 4th rising edge
of input at ICx pin
- Capture timer value on every 16th rising
edge of input at ICx pin
Each input capture channel can select one of the
two 16-bit timers (Timer2 or Timer3) for the time
base. The selected timer can use either an internal
or external clock.
Other operational features include:
• Device Wake-up from Capture Pin during CPU
Sleep and Idle modes
• Interrupt on Input Capture Event
• 4-Word FIFO Buffer for Capture Values
- Interrupt optionally generated after 1, 2, 3 or
4 buffer locations are filled
• Use of Input Capture to provide Additional
Sources of External Interrupts

OUTPUT COMPARE
The output compare module can select either Timer2 or
Timer3 for its time base. The module compares the
value of the timer with the value of one or two Compare
registers depending on the operating mode selected.
The state of the output pin changes when the timer
value matches the Compare register value. The output
compare module generates either a single output
pulse, or a sequence of output pulses, by changing the
state of the output pin on the compare match events.
The output compare module can also generate
interrupts on compare match events.

• Current Compensation
• Enhanced Leading-Edge Blanking (LEB) Functionality

Figure 16-1 conceptualizes the PWM module in a
simplified block diagram. Figure 16-2 illustrates how
the module hardware is partitioned for each PWM
output pair for the Complementary PWM mode.
The PWM module contains nine PWM generators. The
module has up to 18 PWM output pins: PWM1H/
PWM1L through PWM9H/PWM9L. For complementary
outputs, these 18 I/O pins are grouped into high/low
pairs.
16.2
Feature Description
The PWM module is designed for applications that
require:
• High-resolution at high PWM frequencies
• The ability to drive Standard, Edge-Aligned,
Center-Aligned Complementary mode, and
Push-Pull mode outputs
• The ability to create multiphase PWM outputs
For Center-Aligned mode, the duty cycle, period phase
and dead-time resolutions will be 8.32 ns.
Two common, medium power converter topologies are
push-pull and half-bridge. These designs require the
PWM output signal to be switched between alternate
pins, as provided by the Push-Pull PWM mode.
Phase-shifted PWM describes the situation where
each PWM generator provides outputs, but the phase
relationship between the generator outputs is
specifiable and changeable.
Multiphase PWM is often used to improve DC/DC Converter load transient response, and reduce the size of
output filter capacitors and inductors. Multiple DC/DC
Converters are often operated in parallel, but
phase-shifted in time. A single PWM output operating at
250 kHz has a period of 4 s, but an array of four PWM
channels, staggered by 1 s each, yields an effective
switching frequency of 1 MHz. Multiphase PWM
applications typically use a fixed-phase relationship.
Variable phase PWM is useful in Zero Voltage
Transition (ZVT) power converters. Here, the PWM
duty cycle is always 50%, and the power flow is
controlled by varying the relative phase shift between
the two PWM generators.

The smallest pulse width that can be generated on the PWM output corresponds to a value of 0x0008,
while the maximum pulse width generated corresponds to a value of Period – 0x0008.
As the duty cycle gets closer to 0% or 100% of the PWM period (0 to 40 ns, depending on the mode of
operation), the PWM duty cycle resolution will increase from 1 to 3 LSBs.

• The PHASEx/SPHASEx registers provide the phase shift with respect to the master time base;
therefore, the valid range is 0x0000 through period.
If PWMCONx<9> = 1, the following applies based on the mode of operation:
• Complementary, Redundant and Push-Pull Output mode (IOCONx<10:8> = 00, 01 or 10),
PHASEx<15:0> = Independent Time Base Period Value for PWMxH and PWMxL.
• True Independent Output mode (IOCONx<10:8> = 11). PHASEx<15:0> = Independent Time Base

QUADRATURE ENCODER
INTERFACE (QEI) MODULE
This chapter describes the Quadrature Encoder Interface (QEI) module and associated operational modes.
The QEI module provides the interface to incremental
encoders for obtaining mechanical position data.
Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610
families of devices. It is not intended to be
a comprehensive reference source. To
complement the information in this data
sheet, refer to Section 15. “Quadrature
Encoder Interface (QEI)” (DS70208) in
the “dsPIC33F/PIC24H Family Reference
Manual”, which is available from the
Microchip web site (www.microchip.com).
The operational features of the QEI include:
• Three Input Channels for Two Phase Signals and
Index Pulse
• 16-Bit Up/Down Position Counter
• Count Direction Status
• Position Measurement (x2 and x4) mode
• Programmable Digital Noise Filters on Inputs
• Alternate 16-Bit Timer/Counter mode
• Quadrature Encoder Interface Interrupts
These operating modes are determined by setting the
appropriate bits, QEIM<2:0> in (QEIxCON<10:8>).
Figure 17-1 depicts the Quadrature Encoder Interface
block diagram.
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.

FIGURE 18-1:
The Serial Peripheral Interface (SPI) module is a
synchronous serial interface useful for communicating
with other peripheral or microcontroller devices. These
peripheral devices can be serial EEPROMs, shift
registers, display drivers, Analog-to-Digital Converters
and so on. The SPI module is compatible with SPI and
SIOP from Motorola®.
The SPI module consists of a 16-bit shift register,
SPIxSR (where x = 1 or 2), used for shifting data in and
out, and a buffer register, SPIxBUF. A control register,
SPIxCON, configures the module. Additionally, a status
register, SPIxSTAT, indicates status conditions.
The serial interface consists of these four pins:
•
•
•
•
SDIx (Serial Data Input)
SDOx (Serial Data Output)
SCKx (Shift Clock Input Or Output)
SSx (Active-Low Slave Select)
In Master mode operation, SCK is a clock output; in
Slave mode, it is a clock input.

and bit information.
The Inter-Integrated Circuit (I2C) module provides
complete hardware support for both Slave and
Multi-Master modes of the I2C serial communication
standard with a 16-bit interface.
The I2C module has a 2-pin interface:
• The SCLx pin is clock.
• The SDAx pin is data.
The I2C module offers the following key features:
• I2C Interface Supporting Both Master and Slave
modes of Operation
• I2C Slave mode Supports 7-Bit and
10-Bit Addressing
• I2C Master mode Supports 7-Bit and
10-Bit Addressing
• I2C Port allows Bidirectional Transfers Between
Master and Slaves
• Serial Clock Synchronization for I2C Port can be
used as a Handshake Mechanism to Suspend
and Resume Serial Transfer (SCLREL control)
• I2C Supports Multi-Master Operation, Detects Bus
Collision and Arbitrates Accordingly

19.1
Operating Modes
The hardware fully implements all the master and slave
functions of the I2C Standard and Fast mode
specifications, as well as 7-bit and 10-bit addressing.
The I2C module can operate either as a slave or a
master on an I2C bus.
The following types of I2C operation are supported:
•
•
•
I2C slave operation with 7-bit addressing
I2C slave operation with 10-bit addressing
I2C master operation with 7-bit or 10-bit addressing
For details about the communication sequence in each
of these modes, refer to the “dsPIC33F/PIC24H Family
Reference Manual”. Please see the Microchip web site
(www.microchip.com) for the latest “dsPIC33F/PIC24H
Family Reference Manual” sections.
19.2
I2C Registers
I2CxCON and I2CxSTAT are control and status
registers, respectively. The I2CxCON register is
readable and writable. The lower six bits of I2CxSTAT
are read-only. The remaining bits of the I2CSTAT are
read/write:
• I2CxRSR is the shift register used for shifting data
internal to the module and the user application
has no access to it.
• I2CxRCV is the receive buffer and the register to
which data bytes are written or from which data
bytes are read.
• I2CxTRN is the transmit register to which bytes
are written during a transmit operation.
• The I2CxADD register holds the slave address.
• A status bit, ADD10, indicates 10-Bit Addressing
mode.
• The I2CxBRG acts as the Baud Rate Generator
(BRG) reload value.
In receive operations, I2CxRSR and I2CxRCV together
form a double-buffered receiver. When I2CxRSR
receives a complete byte, it is transferred to I2CxRCV
and an interrupt pulse is generated.

50 MIPS
• 4-Deep, First-In First-Out (FIFO) Transmit Data
Buffer
• 4-Deep FIFO Receive Data Buffer
• Parity, Framing and Buffer Overrun Error Detection
• Support for 9-Bit mode with Address Detect
(9th bit = 1)
• Transmit and Receive Interrupts
• A Separate Interrupt for all UART Error Conditions
• Loopback mode for Diagnostic Support
• Support for Sync and Break Characters
• Support for Automatic Baud Rate Detection
• IrDA Encoder and Decoder Logic

Overview
The Enhanced Controller Area Network (ECAN™)
module is a serial interface, useful for communicating with
other CAN modules or microcontroller devices. This interface/protocol was designed to allow communications
within noisy environments. The dsPIC33FJ32GS406/
606/608/610 and dsPIC33FJ64GS406/606/608/610
devices contain up to two ECAN modules.
The ECAN module is a communication controller implementing the CAN 2.0 A/B protocol, as defined in the
BOSCH CAN specification. The module supports
CAN 1.2, CAN 2.0A, CAN 2.0B Passive and CAN 2.0B

The CAN bus module consists of a protocol engine and
message buffering/control. The CAN protocol engine
handles all functions for receiving and transmitting
messages on the CAN bus. Messages are transmitted
by first loading the appropriate data registers. Status
and errors can be checked by reading the appropriate
registers. Any message detected on the CAN bus is
checked for errors and then matched against filters to
see if it should be received and stored in one of the
receive registers.
21.2
Frame Types
The ECAN module transmits various types of frames
which include data messages, or remote transmission
requests initiated by the user, as other frames that are
automatically generated for control purposes. The
following frame types are supported:
• Standard Data Frame: A standard data frame is
generated by a node when the node wishes to
transmit data. It includes an 11-bit Standard Identifier
(SID), but not an 18-bit Extended Identifier (EID).
• Extended Data Frame: An extended data frame is
similar to a standard data frame, but includes an
extended identifier as well.
• Remote Frame: It is possible for a destination
node to request the data from the source. For this
purpose, the destination node sends a remote
frame with an identifier that matches the identifier
of the required data frame. The appropriate data
source node sends a data frame as a response to
this remote request.
• Error Frame: An error frame is generated by any
node that detects a bus error. An error frame consists of two fields: an error flag field and an error
delimiter field.
• Overload Frame: An overload frame can be generated by a node as a result of two conditions.
First, the node detects a dominant bit during interframe space which is an illegal condition. Second,
due to internal conditions, the node is not yet able
to start reception of the next message. A node
can generate a maximum of 2 sequential overload
frames to delay the start of the next message.
• Interframe Space: Interframe space separates a
proceeding frame (of whatever type) from a
following data or remote frame.

21.3
Modes of Operation
The ECAN™ module can operate in one of several
operation modes selected by the user. These modes
include:
•
•
•
•
•
•
Initialization mode
Disable mode
Normal Operation mode
Listen Only mode
Listen All Messages mode
Loopback mode
Modes are requested by setting the REQOP<2:0> bits
(CxCTRL1<10:8>). Entry into a mode is Acknowledged
by monitoring the OPMODE<2:0> bits (CxCTRL1<7:5>).
The module does not change the mode and the
OPMODE bits until a change in mode is acceptable,
generally during bus Idle time, which is defined as at least
11 consecutive recessive bits.
21.3.1
INITIALIZATION MODE
In the Initialization mode, the module does not transmit
or receive. The error counters are cleared and the interrupt flags remain unchanged. The user application has
access to Configuration registers that are access
restricted in other modes. The module protects the user
from accidentally violating the CAN protocol through
programming errors. All registers which control the
configuration of the module cannot be modified while
the module is on-line. The ECAN module is not allowed
to enter the Configuration mode while a transmission is
taking place. The Configuration mode serves as a lock
to protect the following registers:
•
•
•
•
•
All Module Control Registers
Baud Rate and Interrupt Configuration Registers
Bus Timing Registers
Identifier Acceptance Filter Registers
Identifier Acceptance Mask Registers
21.3.2
DISABLE MODE
In Disable mode, the module does not transmit or
receive. The module has the ability to set the WAKIF bit
due to bus activity, however, any pending interrupts
remain and the error counters retains their value.
If the REQOP<2:0> bits (CxCTRL1<10:8>) = 001, the
module enters the Module Disable mode. If the module
is active, the module waits for 11 recessive bits on the
CAN bus, detects that condition as an Idle bus, then
accepts the module disable command. When the
OPMODE<2:0> bits (CxCTRL1<7:5>) = 001, that
indicates whether the module successfully went into
Module Disable mode. The I/O pins revert to normal
I/O function when the module is in the Module Disable
mode.
 2009-2012 Microchip Technology Inc.
The module can be programmed to apply a low-pass
filter function to the CxRX input line while the module or
the CPU is in Sleep mode. The WAKFIL bit
(CxCFG2<14>) enables or disables the filter.
Note:
21.3.3
Typically, if the ECAN module is allowed to
transmit in a particular mode of operation,
and a transmission is requested immediately after the ECAN module has been
placed in that mode of operation, the module waits for 11 consecutive recessive bits
on the bus before starting transmission. If
the user switches to Disable mode within
this 11-bit period, then this transmission is
aborted and the corresponding TXABTmn
bit is set and the TXREQmn bit is cleared.
NORMAL OPERATION MODE
Normal Operation mode is selected when
REQOP<2:0> = 000. In this mode, the module is
activated and the I/O pins assume the CAN bus
functions. The module transmits and receives CAN bus
messages via the CxTX and CxRX pins.
21.3.4
LISTEN ONLY MODE
If the Listen Only mode is activated, the module on the
CAN bus is passive. The transmitter buffers revert to
the port I/O function. The receive pins remain inputs.
For the receiver, no error flags or Acknowledge signals
are sent. The error counters are deactivated in this
state. The Listen Only mode can be used for detecting
the baud rate on the CAN bus. To use this, it is necessary that there are at least two further nodes that
communicate with each other.
21.3.5
LISTEN ALL MESSAGES MODE
The module can be set to ignore all errors and receive
any message. The Listen All Messages mode is activated by setting REQOP<2:0> = 111. In this mode, the
data, which is in the message assembly buffer until the
time an error occurred, is copied in the receive buffer
and can be read via the CPU interface.
21.3.6
LOOPBACK MODE
If the Loopback mode is activated, the module connects the internal transmit signal to the internal receive
signal at the module boundary. The transmit and
receive pins revert to their port I/O function.

Module Description
This ADC module is designed for applications that
require low latency between the request for conversion
and the resultant output data. Typical applications
include:
• AC/DC Power Supplies
• DC/DC Converters
• Power Factor Correction (PFC)
This ADC works with the High-Speed PWM module in
power control applications that require high-frequency
control loops. This module can Sample-and-Convert
two analog inputs in a 0.5 microsecond when two SARs
are used. This small conversion delay reduces the
“phase lag” between measurement and control system
response.
Up to five inputs may be sampled at a time (four inputs
from the dedicated sample and hold circuits and one
from the shared sample and hold circuit). If multiple
inputs request conversion, the ADC will convert them in
a sequential manner, starting with the lowest order
input.
This ADC design provides each pair of analog inputs
(AN1, AN0), (AN3, AN2),..., the ability to specify its own
trigger source out of a maximum of sixteen different
trigger sources. This capability allows this ADC to Sample-and-Convert analog inputs that are associated with
PWM generators operating on independent time
bases.
The user application typically requires synchronization
between analog data sampling and PWM output to the
application circuit. The very high-speed operation of
this ADC module allows “data on demand”.
In addition, several hardware features have been
added to the peripheral interface to improve real-time
performance in a typical DSP-based application.

22.3
Module Functionality
The High-Speed, 10-Bit ADC is designed to support
power conversion applications when used with the
High-Speed PWM module. The ADC may have one or
two SAR modules, depending on the device variant. If
two SARs are present on a device, two conversions
can be processed at a time, yielding 4 Msps conversion
rate. If only one SAR is present on a device, only one
conversion can be processed at a time, yielding 2 Msps
conversion rate. The High-Speed, 10-Bit ADC produces
two 10-bit conversion results in a 0.5 microsecond.
The ADC module supports up to 24 external analog
inputs and two internal analog inputs. To monitor
reference voltage, two internal inputs, AN24 and AN25,
are connected to EXTREF and INTREF, respectively.
The analog reference voltage is defined as the device
supply voltage (AVDD/AVSS).
The ADC module uses the following control and status
registers:
•
•
•
•
•
•
•
•
•
•
•
•
ADCON: ADC Control Register
ADSTAT: ADC Status Register
ADBASE: ADC Base Register(1,2)
ADPCFG: ADC Port Configuration Register
ADPCFG2: ADC Port Configuration Register 2
ADCPC0: ADC Convert Pair Control Register 0
ADCPC1: ADC Convert Pair Control Register 1
ADCPC2: ADC Convert Pair Control Register 2
ADCPC3: ADC Convert Pair Control Register 3
ADCPC4: ADC Convert Pair Control Register 4
ADCPC5: ADC Convert Pair Control Register 5
ADCPC6: ADC Convert Pair Control Register 6(2)
The ADCON register controls the operation of the
ADC module. The ADSTAT register displays the
status of the conversion processes. The ADPCFG
registers configure the port pins as analog inputs or
as digital I/O. The ADCPCx registers control the
triggering of the ADC conversions. See Register 22-1
through Register 22-12 for detailed bit configurations.
Note:
DS70591E-page 310
A unique feature of the ADC module is its
ability to sample inputs in an asynchronous manner. Individual sample and hold
circuits can be triggered independently of
each other.

ADBASE<15:1>: ADC Base Address bits
This register contains the base address of the user’s ADC Interrupt Service Routine jump table. This
register, when read, contains the sum of the ADBASE register contents and the encoded value of the
PxRDY status bits.
The encoder logic provides the bit number of the highest priority PxRDY bits where P0RDY is the
highest priority and P6RDY is the lowest priority.
bit 0
Unimplemented: Read as ‘0’
Note 1:
2:
The encoding results are shifted left two bits so bits 1-0 of the result are always zero.
As an alternative to using the ADBASE register, the ADCP0-ADCP12 ADC pair conversion complete
interrupts can be used to invoke Analog-to-Digital conversion completion routines for individual ADC input
pairs.

and bit information.
23.2
Figure 23-1 shows a functional block diagram of one
analog comparator from the SMPS comparator
module. The analog comparator provides high-speed
operation with a typical delay of 20 ns. The comparator
has a typical offset voltage of ±5 mV. The negative
input of the comparator is always connected to the
DAC circuit. The positive input of the comparator is
connected to an analog multiplexer that selects the
desired source pin.
The dsPIC33F Switch Mode Power Supply (SMPS)
comparator module monitors current and/or voltage
transients that may be too fast for the CPU and ADC to
capture.
23.1
Features Overview
The analog comparator input pins are typically shared
with pins used by the Analog-to-Digital Converter
(ADC) module. Both the comparator and the ADC can
use the same pins at the same time. This capability
enables a user to measure an input voltage with the
ADC and detect voltage transients with the
comparator.
The SMPS comparator module offers the following
major features:
• 16 Selectable Comparator Inputs
• Up to Four Analog Comparators
• 10-Bit DAC for each Analog Comparator

Module Applications
23.5
Interaction with I/O Buffers
This module provides a means for the SMPS dsPIC®
DSC devices to monitor voltage and currents in a
power conversion application. The ability to detect
transient conditions and stimulate the dsPIC DSC
processor and/or peripherals, without requiring the
processor and ADC to constantly monitor voltages or
currents, frees the dsPIC DSC to perform other tasks.
If the comparator module is enabled and a pin has
been selected as the source for the comparator, then
the chosen I/O pad must disable the digital input buffer
associated with the pad to prevent excessive currents
in the digital buffer due to analog input voltages.
The comparator module has a high-speed comparator
and an associated 10-bit DAC that provides a programmable reference voltage to the inverting input of
the comparator. The polarity of the comparator output
is user-programmable. The output of the module can
be used in the following modes:
The CMPCONx register (see Register 23-1) provides
the control logic that configures the comparator
module. The digital logic provides a glitch filter for the
comparator output to mask transient signals in less
than two instruction cycles. In Sleep or Idle mode, the
glitch filter is bypassed to enable an asynchronous
path from the comparator to the interrupt controller.
This asynchronous path can be used to wake-up the
processor from Sleep or Idle mode.

•
Generate an Interrupt
Trigger an ADC Sample-and-Convert Process
Truncate the PWM Signal (current limit)
Truncate the PWM Period (current minimum)
Disable the PWM Outputs (Fault latch)
The output of the comparator module may be used in
multiple modes at the same time, such as: 1) generate
an interrupt, 2) have the ADC take a sample and convert it, and 3) truncate the PWM output in response to
a voltage being detected beyond its expected value.
The comparator module can also be used to wake-up
the system from Sleep or Idle mode when the analog
input voltage exceeds the programmed threshold
voltage.
23.4
DAC
The range of the DAC is controlled via an analog
multiplexer that selects either AVDD/2, an internal reference source, INTREF, or an external reference
source, EXTREF. The full range of the DAC (AVDD/2)
will typically be used when the chosen input source pin
is shared with the ADC. The reduced range option
(INTREF) will likely be used when monitoring current
levels using a current sense resistor. Usually, the
measured voltages in such applications are small
(<1.25V); therefore the option of using a reduced
reference range for the comparator extends the
available DAC resolution in these applications. The
use of an external reference enables the user to
connect to a reference that better suits their
application.
DACOUT, shown in Figure 23-1, can only be
associated with a single comparator at a given time.
Note:
It should be ensured in software that
multiple DACOE bits are not set. The
output on the DACOUT pin will be indeterminate if multiple comparators enable the
DAC output.
23.6
Digital Logic
The comparator can be disabled while in Idle mode if
the CMPSIDL bit is set. If a device has multiple
comparators, if any CMPSIDL bit is set, then the entire
group of comparators will be disabled while in Idle
mode. This behavior reduces complexity in the design
of the clock control logic for this module.
The digital logic also provides a one TCY width pulse
generator for triggering the ADC and generating
interrupt requests.
The CMPDACx (see Register 23-2) register provides
the digital input value to the reference DAC.
If the module is disabled, the DAC and comparator are
disabled to reduce power consumption.
23.7
Comparator Input Range
The comparator has a limitation for the input
Common-Mode Range (CMR) of (AVDD – 1.5V),
typical. This means that both inputs should not exceed
this range. As long as one of the inputs is within the
Common-Mode Range, the comparator output will be
correct. However, any input exceeding the CMR
limitation will cause the comparator input to be
saturated.
If both inputs exceed the CMR, the comparator output
will be indeterminate.
23.8
DAC Output Range
The DAC has a limitation for the maximum reference
voltage input of (AVDD – 1.6) volts. An external
reference voltage input should not exceed this value or
the reference DAC output will become indeterminate.
23.9
Comparator Registers
The comparator module is controlled by the following
registers:
• CMPCONx: Comparator Control x Register
• CMPDACx: Comparator DAC Control x Register

Manual” sections.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices provide
non-volatile memory implementations for device
Configuration bits. Refer to Section 25. “Device
Configuration” (DS70194) in the “dsPIC33F/PIC24H
Family Reference Manual” for more information on this
implementation.
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The individual Configuration bit descriptions for the
Configuration registers are shown in Table 24-2.
The Configuration bits can be programmed (read
as ‘0’), or left unprogrammed (read as ‘1’), to select
various device configurations. These bits are mapped
starting at program memory location 0xF80000.
Note that address, 0xF80000, is beyond the user program memory space. It belongs to the configuration
memory space (0x800000-0xFFFFFF), which can only
be accessed using Table Reads and Table Writes.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices include
several features intended to maximize application
flexibility and reliability, and minimize cost through
elimination of external components. These are:
•
•
•
•
•
•
•
Configuration Bits
To prevent inadvertent configuration changes during
code execution, all programmable Configuration bits
are write-once. After a bit is initially programmed during
a power cycle, it cannot be written again. Changing a
device configuration requires that power to the device
be cycled.

Brown-out Reset (BOR)
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices power
their core digital logic at a nominal 2.5V. This can create
a conflict for designs that are required to operate at a
higher typical voltage, such as 3.3V. To simplify system
design, all devices in the dsPIC33FJ32GS406/606/608/
610 and dsPIC33FJ64GS406/606/608/610 families
incorporate an on-chip regulator that allows the device to
run its core logic from VDD.
The Brown-out Reset (BOR) module is based on an
internal voltage reference circuit. The main purpose of
the BOR module is to generate a device Reset when a
brown-out condition occurs. Brown-out conditions are
generally caused by glitches on the AC mains (for
example, missing portions of the AC cycle waveform
due to bad power transmission lines, or voltage sags
due to excessive current draw when a large inductive
load is turned on).
The regulator provides power to the core from the other
VDD pins. When the regulator is enabled, a low-ESR
(less than 5 ohms) capacitor (such as tantalum or
ceramic) must be connected to the VCAP pin
(Figure 24-1). This helps to maintain the stability of the
regulator. The recommended value for the filter
capacitor is provided in Table 27-13, located in
Section 27.1 “DC Characteristics”.
A BOR generates a Reset pulse, which resets the
device. The BOR selects the clock source based on the
device Configuration bit values (FNOSC<2:0> and
POSCMD<1:0>).
Note:
It is important for the low-ESR capacitor to
be placed as close as possible to the VCAP
pin.
On a POR, it takes approximately 20 s for the on-chip
voltage regulator to generate an output voltage. During
this time, designated as TSTARTUP, code execution is
disabled. TSTARTUP is applied every time the device
resumes operation after any power-down.

If an oscillator mode is selected, the BOR activates the
Oscillator Start-up Timer (OST). The system clock is
held until OST expires. If the PLL is used, the clock is
held until the LOCK bit (OSCCON<5>) is ‘1’.
Concurrently, the Power-up Timer (PWRT) Time-out
(TPWRT) is applied before the internal Reset is
released. If TPWRT = 0 and a crystal oscillator is being
used, then a nominal delay of TFSCM = 100 is applied.
The total delay in this case is TFSCM.
The BOR status bit (RCON<1>) is set to indicate that a
BOR has occurred. The BOR circuit continues to
operate while in Sleep or Idle modes and resets the
device should VDD fall below the BOR threshold
voltage.

For

24.4.1
PRESCALER/POSTSCALER
The nominal WDT clock source from LPRC is
32.767 kHz. This feeds a prescaler that can be configured for either 5-bit (divide-by-32) or 7-bit (divide-by-128)
operation. The prescaler is set by the WDTPRE Configuration bit. With a 32.767 kHz input, the prescaler yields
a nominal WDT Time-out (TWDT) period of 1 ms in 5-bit
mode or 4 ms in 7-bit mode.
A variable postscaler divides down the WDT prescaler
output and allows for a wide range of time-out periods.
The postscaler is controlled by the WDTPOST<3:0>
Configuration bits (FWDT<3:0>), which allow the
selection of 16 settings, from 1:1 to 1:32,768. Using the
prescaler and postscaler, time-out periods, ranging
from 1 ms to 131 seconds, can be achieved.
DS70591E-page 349
dsPIC33FJ32GS406/606/608/610 and dsPIC33FJ64GS406/606/608/610
The WDT, prescaler and postscaler are reset:
24.4.3
• On any device Reset
• On the completion of a clock switch, whether
invoked by software (i.e., setting the OSWEN bit
after changing the NOSC bits) or by hardware
(i.e., Fail-Safe Clock Monitor)
• When a PWRSAV instruction is executed
(i.e., Sleep or Idle mode is entered)
• When the device exits Sleep or Idle mode to
resume normal operation
• By a CLRWDT instruction during normal execution
The WDT is enabled or disabled by the FWDTEN
Configuration bit in the FWDT Configuration register.
When the FWDTEN Configuration bit is set, the WDT is
always enabled.
Note:
24.4.2
The CLRWDT and PWRSAV instructions
clear the prescaler and postscaler counts
when executed.
The WDT can be optionally controlled in software when
the FWDTEN Configuration bit has been programmed
to ‘0’. The WDT is enabled in software by setting the
SWDTEN control bit (RCON<5>). The SWDTEN
control bit is cleared on any device Reset. The software
WDT option allows the user application to enable the
WDT for critical code segments and disable the WDT
during non-critical segments for maximum power
savings.
Note:
SLEEP AND IDLE MODES
If the WDT is enabled, it will continue to run during
Sleep or Idle modes. When the WDT time-out occurs,
the WDT will wake the device and code execution will
continue from where the PWRSAV instruction was
executed. The corresponding SLEEP or IDLE bits
(RCON<3:2>) will need to be cleared in software after
the device wakes up.
FIGURE 24-2:
ENABLING WDT
If the WINDIS bit (FWDT<6>) is cleared,
the CLRWDT instruction should be executed
by the application software only during the
last 1/4 of the WDT period. This CLRWDT
window can be determined by using a timer.
If a CLRWDT instruction is executed before
this window, a WDT Reset occurs.
The WDT flag bit, WDTO (RCON<4>), is not automatically
cleared following a WDT time-out. To detect subsequent
WDT events, the flag must be cleared in software.

When MPLAB ICD 3 is selected as a debugger, the incircuit debugging functionality is enabled. This function
allows simple debugging functions when used with
MPLAB® IDE. Debugging functionality is controlled
through the EMUCx (Emulation/Debug Clock) and
EMUDx (Emulation/Debug Data) pin functions.

Digital Signal Controller just before shipping the
product. Serial programming also allows the most
recent firmware or a custom firmware to be
programmed. Refer to the “dsPIC33F/PIC24H Flash

To use the in-circuit debugger function of the device,
the design must implement ICSP connections to
MCLR, VDD, VSS, PGECx, PGEDx and the EMUDx/
EMUCx pin pair. In addition, when the feature is
enabled, some of the resources are not available for
general use. These resources include the first 80 bytes

The code protection features are controlled by the
Configuration registers: FBS and FGS.
The
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices offer the
intermediate implementation of CodeGuard™ Security.
CodeGuard Security enables multiple parties to securely
share resources (memory, interrupts and peripherals) on
a single chip. This feature helps protect individual
Intellectual Property in collaborative system designs.
Secure segment and RAM protection is not implemented in dsPIC33FJ32GS406/606/608/610 and
dsPIC33FJ64GS406/606/608/610 devices.
Note:
When coupled with software encryption libraries,
CodeGuard Security can be used to securely update
Flash even when multiple IPs reside on a single chip.

INSTRUCTION SET SUMMARY
This data sheet summarizes the features
of the dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the “dsPIC33F/PIC24H
Family Reference Manual”. Please
see
the
Microchip
web
site
(www.microchip.com) for the latest
“dsPIC33F/PIC24H Family Reference
Manual” sections.
The dsPIC33F instruction set is identical to that of the
dsPIC30F.
Most instructions are a single program memory word
(24 bits). Only three instructions require two program
memory locations.
Each single-word instruction is a 24-bit word, divided
into an 8-bit opcode, which specifies the instruction
type and one or more operands, which further specify
the operation of the instruction.
The instruction set is highly orthogonal and is grouped
into five basic categories:
•
•
•
•
•
Word or byte-oriented operations
Bit-oriented operations
Literal operations
DSP operations
Control operations
Table 25-1 shows the general symbols used in
describing the instructions.
The dsPIC33F instruction set summary in Table 25-2
lists all the instructions, along with the status flags
affected by each instruction.
Most word or byte-oriented W register instructions
(including barrel shift instructions) have three
operands:
• The first source operand, which is typically a
register ‘Wb’ without any address modifier
• The second source operand, which is typically a
register ‘Ws’ with or without an address modifier
• The destination of the result, which is typically a
register ‘Wd’ with or without an address modifier
However, word or byte-oriented file register instructions
have two operands:
Most bit-oriented instructions (including
rotate/shift instructions) have two operands:
simple
• The W register (with or without an address
modifier) or file register (specified by the value of
‘Ws’ or ‘f’)
• The bit in the W register or file register
(specified by a literal value or indirectly by the
contents of register ‘Wb’)
The literal instructions that involve data movement can
use some of the following operands:
• A literal value to be loaded into a W register or file
register (specified by ‘k’)
• The W register or file register where the literal
value is to be loaded (specified by ‘Wb’ or ‘f’)
However, literal instructions that involve arithmetic or
logical operations use some of the following operands:
• The first source operand, which is a register ‘Wb’
without any address modifier
• The second source operand, which is a literal
value
• The destination of the result (only if not the same
as the first source operand), which is typically a
register ‘Wd’ with or without an address modifier
The MAC class of DSP instructions can use some of the
following operands:
• The accumulator (A or B) to be used (required
operand)
• The W registers to be used as the two operands
• The X and Y address space prefetch operations
• The X and Y address space prefetch destinations
• The accumulator write-back destination
The other DSP instructions do not involve any
multiplication and can include:
• The accumulator to be used (required)
• The source or destination operand (designated as
Wso or Wdo, respectively) with or without an
address modifier
• The amount of shift specified by a W register,
‘Wn’, or a literal value
The control instructions can use some of the following
operands:
• A program memory address
• The mode of the Table Read and Table Write
instructions
• The file register specified by the value, ‘f’
• The destination, which could be either the file
register, ‘f’, or the W0 register, which is denoted
as ‘WREG’

dsPIC33FJ32GS406/606/608/610 and dsPIC33FJ64GS406/606/608/610
Most instructions are a single word. Certain
double-word instructions are designed to provide all the
required information in these 48 bits. In the second
word, the 8 MSbs are ‘0’s. If this second word is
executed as an instruction (by itself), it will execute as
a NOP.
The double-word instructions execute in two instruction
cycles.
Most single-word instructions are executed in a single
instruction cycle, unless a conditional test is true, or the
Program Counter is changed as a result of the
instruction. In these cases, the execution takes two
instruction cycles with the additional instruction cycle(s)
executed as a NOP. Notable exceptions are the BRA
TABLE 25-1:
(unconditional/computed branch), indirect CALL/GOTO,
all Table Reads and Writes, and RETURN/RETFIE
instructions, which are single-word instructions but take
two or three cycles. Certain instructions that involve
skipping over the subsequent instruction require either
two or three cycles if the skip is performed, depending
on whether the instruction being skipped is a single-word
or two-word instruction. Moreover, double-word moves
require two cycles.

26.5
MPLINK Object Linker/
MPLIB Object Librarian
The MPLINK Object Linker combines relocatable
objects created by the MPASM Assembler and the
MPLAB C18 C Compiler. It can link relocatable objects
from precompiled libraries, using directives from a
linker script.
The MPLIB Object Librarian manages the creation and
modification of library files of precompiled code. When
a routine from a library is called from a source file, only
the modules that contain that routine will be linked in
with the application. This allows large libraries to be
used efficiently in many different applications.
The object linker/library features include:
• Efficient linking of single libraries instead of many
smaller files
• Enhanced code maintainability by grouping
related modules together
• Flexible creation of libraries with easy module
listing, replacement, deletion and extraction

Data in “Typical” column is at 3.3V, +25°C unless otherwise stated.
Base Idle current (IIDLE) is measured as follows:
• CPU core is off, oscillator is configured in EC mode and external clock is active, OSC1 is driven with
external square wave from rail-to-rail (EC clock overshoot/undershoot < 250 mV required)
• CLKO is configured as an I/O input pin in the Configuration Word
• All I/O pins are configured as inputs and pulled to VSS
• MCLR = VDD, WDT and FSCM are disabled
• No peripheral modules are operating; however, every peripheral is being clocked (all PMDx bits are
all ‘0’s)
• JTAG is disabled
These parameters are characterized but not tested in manufacturing.

IPD (Sleep) current is measured as follows:
• CPU core is off, oscillator is configured in EC mode and external clock is active, OSC1 is driven with
external square wave from rail-to-rail (EC clock overshoot/undershoot < 250 mV required)
• CLKO is configured as an I/O input pin in the Configuration Word

• MCLR = VDD, WDT and FSCM are disabled
• All peripheral modules are disabled (all PMDx bits are all ‘1’s)
• The VREGS bit (RCON<8>) = 0 (i.e., core regulator is set to standby while the device is in Sleep
mode)
• JTAG disabled
The  current is the additional current consumed when the WDT module is enabled. This current should
be added to the base IPD current.
These currents are measured on the device containing the most memory in this family.

IDOZE is primarily a function of the operating voltage and frequency. Other factors, such as I/O pin loading
and switching rate, oscillator type, internal code execution pattern and temperature, also have an impact
on the current consumption. The test conditions for all IDOZE measurements are as follows:
• Oscillator is configured in EC mode and external clock is active, OSC1 is driven with external square
wave from rail-to-rail (EC clock overshoot/undershoot < 250 mV required)
• CLKO is configured as an I/O input pin in the Configuration Word
• All I/O pins are configured as inputs and pulled to VSS
• MCLR = VDD, WDT and FSCM are disabled
• CPU, SRAM, program memory and data memory are operational
• No peripheral modules are operating; however, every peripheral is being clocked (all PMDx bits are
all ‘0’s)
• CPU executing while(1) statement
• JTAG disabled

VDD = 3.3V,

Data in “Typ” column is at 3.3V, +25°C unless otherwise stated.
Instruction cycle period (TCY) equals two times the input oscillator time base period. All specified values
are based on characterization data for that particular oscillator type, under standard operating conditions,
with the device executing code. Exceeding these specified limits may result in an unstable oscillator
operation and/or higher than expected current consumption. All devices are tested to operate at “min.”
values with an external clock applied to the OSC1/CLKI pin. When an external clock input is used, the
“max.” cycle time limit is “DC” (no clock) for all devices.
Measurements are taken in EC mode. The CLKO signal is measured on the OSC2 pin.

IDD is primarily a function of the operating voltage and frequency. Other factors, such as I/O pin loading
and switching rate, oscillator type, internal code execution pattern and temperature, also have an impact
on the current consumption. The test conditions for all IDD measurements are as follows:
• Oscillator is configured in EC mode with PLL, OSC1 is driven with external square wave from
rail-to-rail (EC clock overshoot/undershoot < 250 mV required)
• CLKO is configured as an I/O input pin in the Configuration Word
• All I/O pins are configured as inputs and pulled to VSS
• MCLR = VDD, WDT and FSCM are disabled
• CPU, SRAM, program memory and data memory are operational
• No peripheral modules are operating; however, every peripheral is being clocked (all PMDx bits are
zeroed)
• CPU executing while(1) statement
• JTAG is disabled

APPENDIX A:
MIGRATING FROM dsPIC33FJ06GS101/X02 AND
dsPIC33FJ16GSX02/X04 TO dsPIC33FJ32GS406/606/608/610 AND
dsPIC33FJ64GS406/606/608/610 DEVICES
This appendix provides an overview of considerations
for migrating from the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 family of devices to the
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 family of devices.
The code developed for the dsPIC33FJ06GS101/X02
and dsPIC33FJ16GSX02/X04 devices can be ported
to
the
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610
devices
after
making the appropriate changes outlined below.
A.1
Device Pins and Peripheral Pin
Select (PPS)
On
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 devices, some peripherals
such as the Timer, Input Capture, Output Compare,
UART, SPI, External Interrupts, Analog Comparator
Output, as well as the PWM4 pin pair, were mapped to
physical pins via Peripheral Pin Select (PPS)
functionality. On dsPIC33FJ32GS406/606/608/610
and dsPIC33FJ64GS406/606/608/610 devices, these
peripherals are hard-coded to dedicated pins. Because
of this, as well as pinout differences between the two
devices families, software must be updated to utilize
peripherals on the desired pin locations.
A.2
A.2.1
High-Speed PWM
FAULT AND CURRENT-LIMIT
CONTROL SIGNAL SOURCE
SELECTION
Fault and Current-Limit Control Signal Source selection has changed between the two families of devices.
On
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 devices, Fault1 through
Fault8 were assigned to Fault and Current-Limit
Controls with the following values:
•
•
•
•
•
•
•
•
00000 = Fault 1
00001 = Fault 2
00010 = Fault 3
00011 = Fault 4
00100 = Fault 5
00101 = Fault 6
00110 = Fault 7
00111 = Fault 8

A.2.2
ANALOG COMPARATORS
CONNECTION
Connection of analog comparators to the PWM Fault
and Current-Limit Control Signal Sources on
dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices is performed by assigning a comparator to
one of the Fault sources via the virtual PPS pins, and
then selecting the desired Fault as the source for Fault
and Current-Limit Control. On dsPIC33FJ32GS406/
606/608/610 and dsPIC33FJ64GS406/606/608/610
devices, analog comparators have a direct connection
to Fault and Current-Limit Control, and can be selected
with the following values for the CLSRC or FLTSRC
bits:
•
•
•
•
00000 = Analog Comparator 1
00001 = Analog Comparator 2
00010 = Analog Comparator 3
00011 = Analog Comparator 4
A.2.3
LEADING-EDGE BLANKING (LEB)
The Leading-Edge Blanking Delay (LEB) bits have
been moved from the LEBCOx register on
dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices to the LEBDLYx register on
dsPIC33FJ32GS406/606/608/610
and
dsPIC33FJ64GS406/606/608/610 devices.

NOTES:
DS70591E-page 454
 2009-2012 Microchip Technology Inc.
Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
MICROCHIP MAKES NO REPRESENTATIONS OR
WARRANTIES OF ANY KIND WHETHER EXPRESS OR
IMPLIED, WRITTEN OR ORAL, STATUTORY OR
OTHERWISE, RELATED TO THE INFORMATION,
INCLUDING BUT NOT LIMITED TO ITS CONDITION,
QUALITY, PERFORMANCE, MERCHANTABILITY OR
