DIGITAL SIGNAL
CONTROLLERS
Note 1: This data sheet summarizes the features
of the dsPIC33FJ06GS001/101A/102A/
202A and dsPIC33FJ09GS302 family of
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”, 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.
2.1
Basic Connection Requirements
Getting started with the dsPIC33FJ06GS001/101A/
102A/202A and dsPIC33FJ09GS302 family of 16-bit
Digital Signal Controllers (DSCs) 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”)
 2011-2012 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.

As an option, instead of a hard-wired connection, an
inductor (L1) can be substituted between VDD and

impedance should be less than 1 and the inductor
capacity greater than 10 mA.

2.2.1
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 capacitor between 4.7 µF and
10 µF, 16V connected to ground. The type can be
ceramic or tantalum. Refer to Section 25.0 “Electrical
Characteristics” for additional information.

functions:

Regulator (VCAP)
The placement of this capacitor should be close to the

TANK CAPACITORS
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.
FIGURE 2-2:
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.

R  10 k is recommended. A suggested
starting value is 10 k. Ensure that the
MCLR pin VIH and VIL specifications are
met.
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.

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 Input Voltage High (VIH)
and Input Voltage Low (VIL) pin 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 MPLAB ICD 3 and REAL ICE
connection requirements, refer to the following
documents that are available on the Microchip web site
(www.microchip.com):
• “Using MPLAB® ICD 3” (poster) (DS51765)
• “Multi-Tool Design Advisory” (DS51764)
• “MPLAB® REAL ICE™ In-Circuit Emulator 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 8.0 “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 of this range, the
application must start up in the FRC mode first. The
default PLL settings after a POR, with an oscillator
frequency outside of 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 register.
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 register 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 register. 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 2-8.
The bits in the registers that correspond to the
Analog-to-Digital pins that are initialized by MPLAB
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.

3.1
Data Addressing Overview
Note 1: This data sheet summarizes the features
of the dsPIC33FJ06GS001/101A/102A/
202A and dsPIC33FJ09GS302 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).
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.
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.
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 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 dsPIC33FJ06GS001/101A/102A/202A and
dsPIC33FJ09GS302 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: 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 devices are 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.
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.
A block diagram of the CPU is shown in Figure 3-1,
and the programmer’s model is shown in Figure 3-2.

3.3
Special MCU Features
The 16/16 and 32/16 divide operations are supported,
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.
A 17-bit by 17-bit single-cycle multiplier 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 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 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:
•

•
•
•
•

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 dsPIC33FJ06GS001/101A/102A/202A and
dsPIC33FJ09GS302 devices feature 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)

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.
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.
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
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.
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.
• 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

DS75018C-page 33
dsPIC33FJ06GS001/101A/102A/202A and dsPIC33FJ09GS302
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 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:
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:
3.6.3.1
Round Logic
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.
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.‘
• 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).

3.6.3.2
Data Space Write Saturation
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.
If the SATDW bit in the CORCON register is set, data
(after rounding or truncation) is tested for overflow and
adjusted accordingly:
• 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
3.6.4
BARREL SHIFTER
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).
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 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
15 for left shifts.
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.

Program Address Space
The device 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 4.7
“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

PROGRAM MEMORY
ORGANIZATION
4.1.2
All 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 wordaddressable 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 devices also have two interrupt vector tables, 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 are 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 4.7.3 “Reading Data from
Program Memory Using Program Space Visibility”).
All devices implement up to 1 Kbyte 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 byteaddressable, 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 Post-Modified Register
Indirect Addressing mode [Ws++], which 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.
 2011-2012 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.

X AND Y DATA SPACES
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.
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).
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.
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).
All Effective Addresses 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.
DS75018C-page 42
All data memory writes, included 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.

SOFTWARE STACK
In addition to its use as a working register, the W15
register in the 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 postincrements for stack pushes, as shown in Figure 4-5.
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
0x1000 in RAM, initialize the SPLIM with the value
0x0FFE.
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 4-39 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.
4.4.1
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.
4.4.2
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 of the
addressing
modes shown above.
Individual instructions can support
different subsets of these addressing
modes.

FUNDAMENTAL ADDRESSING MODES SUPPORTED
Addressing Mode
File Register Direct
Description
The address of the File register is specified explicitly.
Register Direct
The contents of a register are accessed directly.
Register Indirect
The contents of Wn forms the Effective Address (EA).
Register Indirect Post-Modified
The contents of Wn forms the EA. Wn is post-modified (incremented or
decremented) by a constant value.
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
4.4.3
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)
Register Indirect with Literal Offset

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

4.4.4
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)
4.4.5
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.

4.5
Modulo Addressing
4.5.1
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).
4.5.2
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>.

4.5.3
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:
XB<14:0> is the Bit-Reversed Address 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:
• 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:
4.6
The modulo corrected Effective Address is
written back to the register only when PreModify 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.
4.6.1
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 PostIncrement 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; 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.
BIT-REVERSED ADDRESSING
IMPLEMENTATION
Bit-Reversed Addressing mode is enabled when all of
these conditions are met:
• BWMx bits (W register selection) in the MODCON
register are any value other than ‘15’ (the stack
cannot be accessed using Bit-Reversed
Addressing)
• BREN bit is set in the XBREV register
• 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.

4.7
Interfacing Program and Data
Memory Spaces
4.7.1
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 device 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 device architecture
provides two methods by which program space can be
accessed during operation:
• 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)
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.
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.

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 4-9:
- 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 or TBLRDH).
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 0x8000 and higher
maps directly into a corresponding program memory
address (see Figure 4-10), only the lower 16 bits of the
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.

power (VDD), ground (VSS) and Master Clear (MCLR).
This allows customers to manufacture boards with
unprogrammed devices and then program the digital
signal controller 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 dsPIC33FJ06GS001/101A/

(DS70191) in the “dsPIC33F/PIC24H

RTSP is accomplished using TBLRD (table read) and
TBLWT (table write) instructions. With RTSP, the user
application can write a single program memory word at
a time, and erase program memory in blocks or ‘pages’
of 512 instructions (1536 bytes) at a time.
5.1
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.
These 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:
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.
• In-Circuit Serial Programming™ (ICSP™)

• Run-Time Self-Programming (RTSP)
ICSP allows a dsPIC33FJ06GS001/101A/102A/202A

programmed while in the end application circuit. This is

RTSP Operation
The dsPIC33FJ06GS001/101A/102A/202A and
dsPIC33FJ09GS302 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 25-12 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.
The programming time depends on the FRC accuracy
(see Table 25-19) and the value of the FRC Oscillator
Tuning register (see Register 8-4). 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 25-12).
EQUATION 5-1:
For example, if the device is operating at +125°C, the
FRC accuracy will be ±5%. If the TUN<5:0> bits (see
Register 8-4) are set to ‘b111111, the minimum row
write time is equal to Equation 5-2.

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.

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
(RCON<0> bit) 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
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 bits (COSC<2:0>) in the Oscillator
Control register (OSCCON<14:12>).
There are 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
FNOSC Configuration bits in the FOSC Configuration
register select the device clock source.
TABLE 6-1:
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 provided in Figure 6-2.

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.
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.
PWRT Timer: The programmable Power-up Timer 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.
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 8.0 “Oscillator Configuration” for more information.
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.
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.

applied, and the time SYSRST becomes
inactive, is long enough to get all

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 25.0 “Electrical Characteristics” for details.
The POR status (POR) bit in the Reset Control
(RCON<0>) register is set to indicate the Power-on
Reset.
6.4
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
VBOR threshold and the delay, TBOR, has elapsed. The
delay, TBOR, ensures the voltage regulator output
becomes stable.
The 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 a 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.
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.

6.5
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 25.0 “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.
6.5.1
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 the system is reset.
6.5.2
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.
6.6
Software RESET Instruction (SWR)
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 still remain. SYSRST is
released at the next instruction cycle and the Reset
vector fetch will commence.
The Software Reset (SWR) flag (instruction) in the
Reset Control register (RCON<6>) is set to indicate
the software Reset.
6.7
Watchdog Time-out Reset (WDTO)
Whenever a Watchdog Timer time-out 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.
6.8
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
register (RCON<15>) is set to indicate the Trap Conflict
Reset. Refer to Section 7.0 “Interrupt Controller” for
more information on Trap Conflict Resets.
6.9
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 register
(RCON<14>) is set to indicate the illegal condition
device Reset.
6.9.1
ILLEGAL OPCODE RESET
A device Reset is generated if the device attempts to
execute an illegal opcode value that is fetched from
program memory.
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 0x3F,
which is an illegal opcode value.
6.9.2
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.
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 22.4
“Watchdog Timer (WDT)” for more information on
Watchdog Reset.

(RCON) register after any device Reset to determine
the cause of the Reset.
Note:

INTERRUPT CONTROLLER
Note 1: This data sheet summarizes the features
of the dsPIC33FJ06GS001/101A/102A/
202A and dsPIC33FJ09GS302 families
of devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 41. “Interrupts
(Part IV)” (DS70300) in the “dsPIC33F/
PIC24H Family Reference Manual”,
which is available on 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 interrupt controller reduces the numerous peripheral
interrupt request signals to a single interrupt request
signal to the CPU. The controller 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 non-maskable 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).
 2011-2012 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 devices implement up to 28 unique interrupts and
four 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. A
device clears its registers in response to a Reset, which
forces the PC to zero. The digital signal controller 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 following registers are implemented 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 7-35.
The IPCx registers are used to set the Interrupt Priority
Level (IPL) for each source of interrupt. Each user
interrupt source can be assigned to one of eight priority
levels.

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, 0xE0 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
the interrupt that the ISR handles; otherwise, the 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 the old
CPU priority level.

OSCILLATOR CONFIGURATION
The oscillator system provides:
• External and internal oscillator options as clock
sources
• An on-chip Phase Lock Loop (PLL) to scale the
internal operating frequency to the required system
clock frequency
• An internal FRC oscillator that can also be used with
the PLL, thereby allowing full-speed operation
without any external clock generation hardware
• Clock switching between various clock sources
• Programmable clock postscaler for system power
savings
• A Fail-Safe Clock Monitor (FSCM) that detects clock
failure and takes fail-safe measures
• An Oscillator Control register (OSCCON)
• Nonvolatile Configuration bits for main oscillator
selection
• An auxiliary PLL for ADC and PWM
A simplified diagram of the oscillator system is shown
in Figure 8-1.

FRC Oscillator with PLL
Primary (XT, HS or EC) Oscillator
Primary Oscillator with PLL
Low-Power RC (LPRC) Oscillator
FRC Oscillator with Postscaler

The FRC frequency depends on the FRC accuracy
(see Table 25-20) and the value of the FRC Oscillator
Tuning register (see Register 8-4).
8.1.2
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:
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 22.1 “Configuration Bits” for further
details.) The initial Oscillator Selection 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.
• 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 32 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.
The Configuration bits allow users to choose among
12 different clock modes, shown in Table 8-1.
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).
Instruction execution speed or device operating
frequency, FCY, is given by Equation 8-1.
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
40 MHz are supported by the device architecture.
EQUATION 8-1:
The clock signals generated by the FRC and primary
oscillators can be optionally applied to an on-chip
Phase Lock Loop (PLL) to provide a wide range of

PLL CONFIGURATION
• If PLLPOST<1:0> = 00, then N2 = 2. This provides a FOSC of 160/2 = 80 MHz. The resultant
device operating speed is 80/2 = 40 MIPS.
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 8-2.

EXAMPLE
1
* 32
( 10000000
) = 40 MIPS
2*2
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>).
8.2
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 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.
• For proper PWM operation, auxiliary clock generation must be configured for 120 MHz (see
Parameter OS56 in Table 25-18 in Section 25.0
“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
FOSC CALCULATION
(N1 M* N2)
For example, suppose a 10 MHz crystal is being used
with the selected oscillator mode of XT with PLL (see
Equation 8-3).
8.3
• If PLLPRE<4:0> = 0, 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> = 0x1E, then M = 32. This yields a
VCO output of 5 x 32 = 160 MHz, which is within
the 100-200 MHz ranged needed.
FIGURE 8-2:
Auxiliary Clock Generation
The auxiliary clock has the following configuration
restrictions:
For a primary oscillator or FRC oscillator, output ‘FIN’,
the PLL output ‘FOSC’, is given by Equation 8-2.
FOSC = FIN *
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 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 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 80 MHz, which
generates device operating speeds of 6.25-40 MIPS.

8.5
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, devices have a safeguard lock
built into the switch process.
Note:
8.5.1
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.
Once the basic sequence is completed, the system
clock hardware responds automatically as follows:
1.
2.
3.
ENABLING CLOCK SWITCHING
To enable clock switching, the FCKSM1 Configuration bit
in the FOSC Configuration register must be programmed
to ‘0’. (Refer to Section 22.1 “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.
4.
The NOSC<2:0> control bits (OSCCON<10:8>) do not
control the clock selection when clock switching
is disabled. However, the COSC<2:0> bits
(OSCCON<14:12>) reflect the clock source selected
by the FNOSC Configuration bits.
6.
The OSWEN control bit (OSCCON<0>) has no effect
when clock switching is disabled. It is held at ‘0’ at all
times.
8.5.2
OSCILLATOR SWITCHING SEQUENCE
To perform a clock switch, the following basic sequence
is required:
1.
2.
3.
4.
5.
If desired, read the COSC<2:0> bits 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 NOSC<2:0>
control bits 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.
DS75018C-page 134
5.
The clock switching hardware compares the
COSC<2:0> status bits with the new value of the
NOSC<2:0> 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.
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
NOSC<2:0> bit values are transferred to the
COSC<2:0> status bits.
The old clock source is turned off at this time,
with the exception of LPRC (if WDT or FSCM is
enabled).
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.

8.6
Fail-Safe Clock Monitor (FSCM)
8.7
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.
The pseudo-random generator is implemented with a
15-bit Linear Feedback Shift Register (LFSR), which is
a shift register with a few exclusive OR gates. The shift
register is clocked by the PWM clock and is a read-only
register. The purpose of this feature is to provide the
ability to randomly change the period or the active
portion of the PWM.
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.
A firmware routine can be used to read “n” random bits
from the LFSR register and combine them, by either
summing or performing another logical operation with
the PWM period of the Duty Cycle registers. The result
will be a PWM signal whose nominal period (or duty
cycle) is the desired one, but whose effective value
changes randomly. This capability will help in reducing
the EMI/EMC emissions by spreading the power over a
wider frequency range.
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 dsPIC33FJ06GS001/101A/102A/
202A and dsPIC33FJ09GS302 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 (WDT) 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.
These 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.
9.1
Clock Frequency and Clock
Switching
These 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 NOSC<2:0> 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 8.0 “Oscillator
Configuration”.
EXAMPLE 9-1:
9.2
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 9-1.
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.
9.2.1
SLEEP MODE
The following occur 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 items, such as the Input
Change Notification (ICN) 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.

dsPIC33FJ06GS001/101A/102A/202A and dsPIC33FJ09GS302
9.2.2
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 9.4
“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.
9.2.3
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.
9.3
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 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.
9.4
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.
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.
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).
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.

I/O PORTS
Note 1: This data sheet summarizes the features
of the dsPIC33FJ06GS001/101A/102A/
202A and dsPIC33FJ09GS302 family 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 on 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.
10.1
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 10-1 shows
how ports are shared with other peripherals and the
associated I/O pin to which they are connected.

10.2
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 the “Pin Diagrams” section for the available
pins and their functionality.
10.3
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 register has a default value of 0x0000;
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.

0xFF00, W0
W0, TRISBB
PORTB, #13
10.4
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 10-1.
10.5
Input Change Notification
The Input Change Notification function of the I/O
ports allows 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 (COS), even in Sleep mode when
the clocks are disabled. Depending on the device pin
count, up to 16 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 register contains the interrupt
enable control bits for each of the CN input pins. Setting
any of these bits enables a CN interrupt for the
corresponding pin.
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 register, which contains 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.

10.6
Peripheral Pin Select (PPS)
Peripheral Pin Select configuration enables peripheral
set selection and placement on a wide range of I/O
pins. By increasing the pinout options available on a
particular device, programmers can better tailor the
microcontroller to their entire application, rather than
trimming the application to fit the device.
The Peripheral Pin Select configuration feature operates
over a fixed subset of digital I/O pins. Programmers can
independently map the input and/or output of most
digital peripherals to any one of these I/O pins.
Peripheral Pin Select is performed in software and generally does not require the device to be reprogrammed.
Hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping once
it has been established.
10.6.1
AVAILABLE PINS
The Peripheral Pin Select feature is used with a range
of up to 16 pins. The number of available pins depends
on the particular device and its pin count. Pins that
support the Peripheral Pin Select feature include the
designation, “RPn”, in their full pin designation, where
“RP” designates a remappable peripheral and “n” is the
remappable pin number.
10.6.2
10.6.2.1
The inputs of the Peripheral Pin Select options are
mapped on the basis of the peripheral. A control register
associated with a peripheral dictates the pin it will be
mapped to. The RPINRx registers are used to configure
peripheral input mapping (see Register 10-1 through
Register 10-15). Each register contains sets of 6-bit
fields, with each set associated with one of the
remappable peripherals. Programming a given
peripheral’s bit field with an appropriate 6-bit value maps
the RPn pin with that value to that peripheral. For any
given device, the valid range of values for any bit field
corresponds to the maximum number of Peripheral Pin
Selections supported by the device.
Figure 10-2 illustrates the remappable pin selection for
the U1RX input.
Note:
The association of a peripheral to a peripheral selectable pin is handled in two different ways, depending on
whether an input or output is being mapped.
For input mapping only, the Peripheral Pin
Select (PPS) functionality does not have
priority over the TRISx settings. Therefore, when configuring the RPx pin for
input, the corresponding bit in the TRISx
register must also be configured for input
(i.e., set to ‘1’).
FIGURE 10-2:
CONTROLLING PERIPHERAL PIN
SELECT
Peripheral Pin Select features are controlled through
two sets of Special Function Registers: one to map
peripheral inputs and one to map outputs. Because
they are separately controlled, a particular peripheral’s
input and output (if the peripheral has both) can be
placed on any selectable function pin without
constraint.

10.6.2.2
Output Mapping
FIGURE 10-3:
In contrast to inputs, the outputs of the Peripheral Pin
Select options are mapped on the basis of the pin. In
this case, a control register associated with a particular
pin dictates the peripheral output to be mapped. The
RPORx registers are used to control output mapping.
Like the RPINRx registers, each register contains sets
of 6-bit fields, with each set associated with one RPn
pin (see Register 10-16 through Register 10-25). The
value of the bit field corresponds to one of the
peripherals and that peripheral’s output is mapped to
the pin (see Table 10-2 and Figure 10-3).
The list of peripherals for output mapping also includes
a null value of ‘00000’ because of the mapping
technique. This permits any given pin to remain
unconnected from the output of any of the pin
selectable peripherals.

10.6.2.3
Virtual Pins
Four virtual RPn pins (RP32, RP33, RP34 and RP35)
are supported, which are identical in functionality to all
other RPn pins, with the exception of pinouts. These
four pins are internal to the devices and are not
connected to a physical device pin.
These pins provide a simple way for inter-peripheral
connection without utilizing a physical pin. For example,
the output of the analog comparator can be connected to
RP32 and the PWM Fault input can be configured for
RP32 as well. This configuration allows the analog
comparator to trigger PWM Faults without the use of an
actual physical pin on the device.
10.6.3
CONTROLLING CONFIGURATION
CHANGES
Because peripheral remapping can be changed during
run time, some restrictions on peripheral remapping
are needed to prevent accidental configuration
changes. dsPIC33F devices include three features to
prevent alterations to the peripheral map:
• Control register lock sequence
• Continuous state monitoring
• Configuration bit pin select lock
10.6.3.1
Control Register Lock
Under normal operation, writes to the RPINRx and
RPORx registers are not allowed. Attempted writes
appear to execute normally, but the contents of the
registers remain unchanged. To change these
registers, they must be unlocked in hardware. The
register lock is controlled by the IOLOCK bit
(OSCCON<6>). Setting IOLOCK prevents writes to the
control registers; clearing IOLOCK allows writes.
Unlike the similar sequence with the oscillator’s LOCK
bit, IOLOCK remains in one state until changed. This
allows all of the Peripheral Pin Selects to be configured
with a single unlock sequence, followed by an update
to all control registers, then locked with a second lock
sequence.
10.6.3.2
Continuous State Monitoring
In addition to being protected from direct writes, the
contents of the RPINRx and RPORx registers are
constantly monitored in hardware by shadow registers.
If an unexpected change in any of the registers occurs
(such as cell disturbances caused by ESD or other
external events), a Configuration Mismatch Reset will
be triggered.
10.6.3.3
Configuration Bit Pin Select Lock
As an additional level of safety, the device can be
configured to prevent more than one write session to
the RPINRx and RPORx registers. The IOL1WAY
(FOSC<5>) Configuration bit blocks the IOLOCK bit
from being cleared, after it has been set once. If
IOLOCK remains set, the register unlock procedure will
not execute and the Peripheral Pin Select Control
registers cannot be written to. The only way to clear the
bit and re-enable peripheral remapping is to perform a
device Reset.
In the default (unprogrammed) state, IOL1WAY is set,
restricting users to one write session. Programming
IOL1WAY allows user applications unlimited access
(with the proper use of the unlock sequence) to the
Peripheral Pin Select registers.
To set or clear IOLOCK, a specific command sequence
must be executed:
1.
2.
3.
Write 0x46 to OSCCON<7:0>.
Write 0x57 to OSCCON<7:0>.
Clear (or set) IOLOCK as a single operation.
Note:
MPLAB® C30 provides built-in C
language functions for unlocking the
OSCCON register:
__builtin_write_OSCCONL(value)
__builtin_write_OSCCONH(value)
See the MPLAB C30 Help files for more
information.

In some cases, certain pins, as defined in
Table 25-9 under “Injection Current”, have internal
protection diodes to VDD and VSS. The term,
“Injection Current”, is also referred to as “Clamp
Current”. On designated pins, with sufficient external current limiting precautions by the user, I/O pin
input voltages are allowed to be greater or less
than the data sheet absolute maximum ratings
with respect to the VSS and VDD supplies. Note
that when the user application forward biases
either of the high or low side internal input clamp
diodes, that the resulting current being injected
into the device that is clamped internally by the
VDD and VSS power rails, may affect the ADC
accuracy by four to six counts.
I/O pins that are shared with any analog input pin
(i.e., ANx) are always analog pins by default after
any Reset. Consequently, any pin(s) configured as
an analog input pin, automatically disables the digital input pin buffer. As such, any attempt to read a
digital input pin will always return a ‘0’, regardless
of the digital logic level on the pin if the analog pin
is configured. To use a pin as a digital I/O pin on a
shared ANx pin, the user application needs to configure the Analog Pin register in the ADC module
(i.e., ADPCFG) by setting the appropriate bit that
corresponds to that I/O port pin to a ‘1’. On devices
with more than one ADC, both analog pin configurations for both ADC modules must be configured
as a digital I/O pin for that pin to function as a
digital I/O pin.
Note:
3.
I/O Helpful Tips
Although it is not possible to use a digital
input pin when its analog function is
enabled, it is possible to use the digital I/O
output function, TRISx = 0x0, while the
analog function is also enabled. However,
this is not recommended, particularly if the
analog input is connected to an external
analog voltage source, which would
create signal contention between the
analog signal and the output pin driver.
Most I/O pins have multiple functions. Referring to
the device pin diagrams in the data sheet, the
priorities of the functions allocated to any pins are
indicated by reading the pin name from left-to-right.
The left most function name takes precedence over
any function to its right in the naming convention; for
example: AN2/CMP1C/CMP2A/RA2. This indicates that AN2 is the highest priority in this example
and will supersede all other functions to its right in
the list. Those other functions to its right, even if
enabled, would not work as long as any other function to its left was enabled. This rule applies to all of
the functions listed for a given pin.

Each CN pin has a configurable internal weak
pull-up resistor. The pull-ups act as a current
source connected to the pin and eliminates the
need for external resistors in certain applications. The internal pull-up is to ~(VDD – 0.8), not
VDD. This is still above the minimum VIH of
CMOS and TTL devices.
When driving LEDs directly, the I/O pin can
source or sink more current than what is
specified in the VOH/IOH and VOL/IOL DC Characteristics specification. The respective IOH and
IOL current rating only applies to maintaining the
corresponding output at or above the VOH, and
at or below the VOL levels. However, for LEDs,
unlike digital inputs of an externally connected
device, they are not governed by the same minimum VIH/VIL levels. An I/O pin output can safely
sink or source any current less than that listed in
the “Absolute Maximum Ratings(1)” in
Section 25.0, Electrical Characteristics of this
data sheet. For example:
VOH = 2.4V @ IOL = -6 mA and VDD = 3.3V
The maximum output current sourced by any
4x I/O pin = 15 mA.
LED source current <15 mA is technically permitted.
Refer to the VOH/IOH graphs in Section 26.0 “DC
and AC Device Characteristics Graphs” for
additional information.

TIMER1
The unique features of Timer1 allow it to be used for
Real-Time Clock applications. A block diagram of
Timer1 is shown in Figure 11-1.
Note 1: This data sheet summarizes the features
of the dsPIC33FJ06GS001/101A/102A/
202A and dsPIC33FJ09GS302 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 Timer1 modes are determined by the following bits:
• Timer1 Clock Source Control bit: TCS (T1CON<1>)
• Timer1 Synchronization Control bit: TSYNC
(T1CON<2>)
• Timer1 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 Timer1 control bit settings for different operating
modes are given in the Table 11-1.
The Timer1 module has the following unique features
over other timers:
TABLE 11-1:
• Can be operated from the low-power 32 kHz
crystal oscillator available on the device
• Can be operated in Asynchronous Counter mode
from an external clock source
• The Timer1 External Clock Input (T1CK) can
optionally be synchronized to the internal device
clock and the clock synchronization is performed
after the prescaler

The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The input capture module captures the 16-bit value of
the selected Time Base register when an event occurs
at the IC1 pin. The events that cause a capture event
are listed below in three categories:
FIGURE 13-1:
• Simple Capture Event modes:
- Capture timer value on every falling edge of
input at IC1 pin
- Capture timer value on every rising edge of
input at IC1 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 IC1 pin
- Capture timer value on every 16th rising
edge of input at IC1 pin
The input capture module uses the Timer2 module
as its timer; however, it 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

The high-speed PWM module supports a wide variety
of PWM modes and output formats. This PWM module
is ideal for power conversion applications, such as:

•
•
•
•
•
•
AC/DC Converters
DC/DC Converters
Power Factor Correction (PFC)
Uninterruptible Power Supply (UPS)
Inverters

Features Overview
The high-speed PWM module incorporates the
following features:
• Two to three PWM generators with four to six
outputs
• Individual time base and duty cycle for each of the
six PWM outputs
• Dead time for rising and falling edges:
• Duty cycle resolution of 1.04 ns(1,2)
• Dead-time resolution of 1.04 ns(1,2)
• Phase-shift resolution of 1.04 ns(1,2)
• Frequency resolution of 1.04 ns(1,2)
Note 1: Resolution is 8.32 ns in Center-Aligned
PWM mode.
2: Resolution is 8.32 ns for
dsPIC33FJ06GS001 devices.
 2011-2012 Microchip Technology Inc.
• Supported PWM modes:
- Standard Edge-Aligned
- True Independent Output
- Complementary
- Center-Aligned
- Push-Pull
- Multiphase
- Variable Phase
- Fixed Off Time
- Current Reset
- Current Limit
• Independent Fault/Current-Limit inputs for each of
the six PWM outputs
• Output override control
• Special Event Trigger
• PWM capture feature
• Prescaler for input clock
• Dual trigger from PWM to ADC
• PWMxH, PWMxL output pin swapping
• Remappable PWM4H, PWM4L pins
• On-the-fly PWM frequency, duty cycle and
phase-shift changes
• Disabling of individual PWM generators to reduce
power consumption
• Leading-Edge Blanking (LEB) functionality
• PWM output chopping (see Note 1)
Note 1: The chopping function performs a logical
AND of the PWM outputs with a very
high-frequency clock signal. The chopping frequency is typically hundreds or
thousands of time higher in frequency, as
compared to the PWM frequency. Chopping a PWM signal constrains the use of
a pulse transformer to cross the isolation
barrier.
Figure 15-1 conceptualizes the PWM module in a
simplified block diagram. Figure 15-2 illustrates how
the module hardware is partitioned for each PWM output pair for the Complementary PWM mode. Each
functional unit of the PWM module is discussed in
subsequent sections.
The PWM module contains three PWM generators.
The module has up to six PWM output pins: PWM1H,
PWM1L, PWM2H, PWM2L, PWM4H and PWM4L. For
complementary outputs, these six I/O pins are grouped
into H/L pairs.

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.
A 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.
A 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.
A phase-shifted PWM describes the situation where
each PWM generator provides outputs, but the phase
relationship between the generator outputs is
specifiable and changeable.

The smallest pulse width that can be generated on the PWM output corresponds to a value of 0x0009,
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 ns-40 ns, depending on the mode of
operation), the PWM duty cycle resolution will degrade from 1 LSb to 3 LSbs.

SERIAL PERIPHERAL
INTERFACE (SPI)
Note 1: This data sheet summarizes the features
of the dsPIC33FJ06GS001/101A/102A/
202A and dsPIC33FJ09GS302 family of
devices. It is not intended to be a comprehensive reference source. To complement
the information in this data sheet, refer to
Section 18. “Serial Peripheral Interface
(SPI)” (DS70206) of 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.
FIGURE 16-1:
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,
etc. The SPI module is compatible with Motorola® SPI
and SIOP.
Each 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 4 pins:
•
•
•
•
SDIx (serial data input)
SDOx (serial data output)
SCKx (shift clock input or output)
SSx (active-low slave select)
In Master mode operation, SCKx is a clock output; in
Slave mode, it is a clock input.

16.1
1.
In Frame mode, if there is a possibility that the
master may not be initialized before the slave:
a) If FRMPOL (SPIxCON2<13>) = 1, use a
pull-down resistor on SSx.
b) If FRMPOL = 0, use a pull-up resistor on
SSx.
Note:
2.
This will insure that during power-up and
initialization the master/slave will not lose
Sync due to an errant SCK transition that
would cause the slave to accumulate data
shift errors for both transmit and receive
appearing as corrupted data.
To avoid invalid slave read data to the master, the
user’s master software must ensure enough time for
slave software to fill its write buffer before the user
application initiates a master write/read cycle. It is
always advisable to preload the SPIxBUF Transmit
register in advance of the next master transaction
cycle. SPIxBUF is transferred to the SPI Shift register
and is empty once the data transmission begins.
16.2
SPI Resources
Many useful resources related to SPI are provided on
the Microchip web site (www.microchip.com).
16.2.1
KEY RESOURCES
• Section 18. “Serial Peripheral Interface (SPI)”
(DS70206)
• Code Samples
• Application Notes
• Software Libraries
• Webinars
• All related “dsPIC33F/PIC24H Family Reference
Manual” Sections
• Development Tools
FRMEN (SPIxCON2<15>) = 1 and SSEN
(SPIxCON1<7>) = 1 are exclusive and invalid.
In Frame mode, SCKx is continuous and the
Frame Sync pulse is active on the SSx pin,
which indicates the start of a data frame.
Note:
4.
This insures that the first frame
transmission after initialization is not
shifted or corrupted.
In Non-Framed 3-Wire mode, (i.e., not using
SSx from a master):
a) If CKP (SPIxCON1<6>) = 1, always place a
pull-up resistor on SSx.
b) If CKP = 0, always place a pull-down
resistor on SSx.
Note:
3.
SPI Helpful Tips
Not all third-party devices support Frame
mode timing. Refer to the SPI electrical
characteristics for details.
In Master mode only, set the SMP bit
(SPIxCON1<9>) to a ‘1’ for the fastest SPI data
rate possible. The SMP bit can only be set at the
same time or after the MSTEN bit
(SPIxCON1<5>) is set.

17.1
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, please see the Microchip web site
(www.microchip.com) for the latest “dsPIC33F/PIC24H
Family Reference Manual” sections.
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 SCL1 pin is the clock
• The SDA1 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

I2C Registers
• I2C1TRN is the transmit register to which bytes
are written during a transmit operation
• The I2C1ADD register holds the slave address
• A status bit, ADD10, indicates 10-Bit Address
mode
• The I2C1BRG acts as the Baud Rate Generator
(BRG) reload value
I2C1CON and I2C1STAT are control and status
registers, respectively. The I2C1CON register is
readable and writable. The lower six bits of I2C1STAT
are read-only. The remaining bits of the I2CSTAT are
read/write:
• I2C1RSR is the shift register used for shifting data
internal to the module and the user application
has no access to it
• I2C1RCV is the receive buffer and the register to
which data bytes are written, or from which data
bytes are read
REGISTER 17-1:
In receive operations, I2C1RSR and I2C1RCV
together form a double-buffered receiver. When
I2C1RSR receives a complete byte, it is transferred to
I2C1RCV, and an interrupt pulse is generated.

RECEIVER TRANSMITTER
(UART)
Note 1: This data sheet summarizes the features
of the dsPIC33FJ06GS001/101A/102A/
202A and dsPIC33FJ09GS302 family of
devices. It is not intended to be a

The Universal Asynchronous Receiver Transmitter
(UART) module is a serial I/O module. The UART is a
full-duplex, asynchronous system that can communicate
with peripheral devices, such as personal computers,
LIN/J2602, RS-232 and RS-485 interfaces. The module
also supports a hardware flow control option with the
U1CTS and U1RTS pins, and also includes an IrDA®
encoder and decoder.
Note:
The dsPIC33FJ06GS001 device does not
have a UART module.
FIGURE 18-1:
The primary features of the UART module are:
• Full-duplex, 8-bit or 9-bit data transmission
through the U1TX and U1RX pins
• Even, Odd or No Parity options (for 8-bit data)
• One or two Stop bits
• Hardware flow control option with U1CTS and
U1RTS pins
• Fully integrated Baud Rate Generator (BRG) with
16-bit prescaler
• Baud rates ranging from 10 Mbps to 38 bps at
40 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
• 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
• 16x baud clock output for IrDA® support
A simplified block diagram of the UART module is
shown in Figure 18-1. The UART module consists of
these key hardware elements:
• BRG
• Asynchronous transmitter
• Asynchronous receiver

UART Helpful Tips
In multinode, direct-connect UART networks,
UART receive inputs react to the complementary logic level defined by the URXINV bit
(U1MODE<4>), which defines the Idle state, the
default of which is logic high, (i.e., URXINV = 0).
Because remote devices do not initialize at the
same time, it is likely that one of the devices,
because the RX line is floating, will trigger a
Start bit detection and will cause the first byte
received after the device has been initialized to
be invalid. To avoid this situation, the user
should use a pull-up or pull-down resistor on the
RX pin, depending on the value of the URXINV
bit.
a) If URXINV = 0, use a pull-up resistor on the
RX pin.
b) If URXINV = 1, use a pull-down resistor on
the RX pin.
The first character received on a wake-up from
Sleep mode, caused by activity on the UxRX pin
of the UART module, will be invalid. In Sleep
mode, peripheral clocks are disabled. By the time
the oscillator system has restarted and stabilized
from Sleep mode, the baud rate bit sampling
clock, relative to the incoming UxRX bit timing, is
no longer synchronized. This results in the first
character being invalid; this is to be expected.

19.2
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:
Up to three inputs may be sampled at a time (two 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:
•
•
•
•
Result alignment options
Automated sampling
External conversion start control
Two internal inputs to monitor INTREF and
EXTREF input signals (not available in
dsPIC33FJ06GS101A/102A devices)
Block diagrams of the ADC module are shown in
Figure 19-1 through Figure 19-5.
19.3
Module Functionality
The high-speed, 10-bit ADC module is designed to
support power conversion applications when used with
the high-speed PWM module. The ADC has one SAR
and only one conversion can be processed at a time,
yielding a conversion rate of 2 Msps or the equivalent of
one 10-bit conversion, in half a microsecond (0.5 µs).
The ADC module supports up to eight external analog
inputs and two internal analog inputs. To monitor
reference voltage, two internal inputs, AN12 and AN13,
are connected to the EXTREF and INTREF voltages,
respectively.
Note:
The dsPIC33FJ06GS101A/102A devices
do not have the internal connection to
EXTREF.
The analog reference voltage is defined as the device
supply voltage (AVDD/AVSS).
• 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 small conversion delay reduces the
“phase lag” between measurement and control system
response.

The ADC module uses the following control and status
registers:
•
•
•
•
•
•
•
ADCON: ADC Control Register
ADSTAT: ADC Status Register
ADBASE: ADC Base Register(1)
ADPCFG: ADC Port Configuration Register
ADCPC0: ADC Convert Pair Control Register 0
ADCPC1: ADC Convert Pair Control Register 1
ADCPC3: ADC Convert Pair Control Register 3(1)
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.
The ADCON register controls the operation of the
ADC module. The ADSTAT register displays the
status of the conversion processes. The ADPCFG
register configures the port pins as analog inputs or
as digital I/Os. The ADCPCx registers control the
triggering of the ADC conversions. See Register 19-1
through Register 19-7 for detailed bit configurations.

As an alternative to using the ADBASE register, the ADCP0-6 ADC Pair Conversion Complete Interrupts
can be used to invoke A to D conversion completion routines for individual ADC input pairs.
The encoding results are shifted left two bits, so bits 1-0 of the result are always zero.

20.2
Figure 20-1 shows a functional block diagram of one
analog comparator from the high-speed analog
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 high-speed analog comparator module monitors
current and/or voltage transients that may be too fast
for the CPU and ADC to capture.
20.1
Features Overview
The SMPS comparator module offers the following
major features:
•
•
•
•
•
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.
Eight selectable comparator inputs
Up to two analog comparators
10-bit DAC for each analog comparator
Programmable output polarity
Interrupt generation capability

20.3
Module Applications
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.
The comparator module has a high-speed comparator,
an associated 10-bit DAC and a DAC output amplifier
that provide 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:
•
•
•
•
•
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.
20.4
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 20-1, 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.
DS75018C-page 244
20.5
DAC Buffer Gain
The output of the DAC is buffered/amplified via the
DAC buffer. The block functions as a 1x gain amplifier
or as a 1.8x gain amplifier. The gain selection is controlled via the HGAIN bit in the CMPCONx register.
Using the 1.8x gain option will raise the reference
voltage to the analog comparator to a maximum of
2.8V. Using a higher reference voltage for the analog
comparator can improve the signal-to-noise ratio in an
application.
20.6
Comparator Input Range
The comparator has an input voltage range from -0.2V
to AVDD + 0.2V, making it a rail-to-rail input.
20.7
Digital Logic
The CMPCONx register (see Register 20-1) provides
the control logic that configures the High-Speed Analog
Comparator module. The digital logic provides a pulse
stretcher. The analog comparator can respond to very
fast transient signals. After the comparator output is
given the desired polarity, the signal is passed to this
pulse stretching circuit. The pulse stretching circuit has
an asynchronous set function and a delay circuit that
insure the minimum pulse width is three system clock
cycles wide so that the attached circuitry can properly
respond.
The stretch circuit is followed by a digital filter. The
digital filter is enabled via the FLTREN bit in the
CMPCONx register. The digital filter operates with the
clock specified via the FCLKSEL bit in the CMPCONx
register. The comparator signal must be stable in a high
or low state for at least three of the selected clock
cycles for it to pass through the digital filter.
During Sleep mode, the clock signal inputs to the
module are disabled. However, the module’s analog
components may continue to function in a reduced
power manner to allow the user to wake-up the device
when a signal is applied to a comparator input.
In Sleep mode, the clocks are stopped; however, the
analog comparator signal has an asynchronous connection across the filter that allows interrupts to be
generated regardless of the stopped clocks.
The comparator can be disabled while in Idle mode if
the CMPSIDL bit is set. If a device has multiple comparators, and any CMPSIDL bit is set, the entire group of
comparators will be disabled while in Idle mode. The
advantage is reduced power consumption. Moreover,
this behavior reduces complexity in the design of the
clock control logic for this module.

20.8
Hysteresis
20.9
An additional feature of the module is hysteresis control. Hysteresis can be enabled or disabled and its
amplitude can be controlled by the HYSSEL<1:0> bits
in the CMPCONx register. Three different values are
available: 15 mV, 30 mV and 45 mV. It is also possible
to select the edge (rising or falling) to which hysteresis
is to be applied.
Hysteresis control prevents the comparator output from
continuously changing state because of small
perturbations (noise) at the input (see Figure 20-2).
FIGURE 20-2:
HYSTERESIS CONTROL
Interaction with I/O Buffers
If the 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.
20.10 DAC Output Range
The DAC has a limitation for the maximum reference
voltage input of (AVDD – 1.5) volts. An external
reference voltage input should not exceed this value or
the reference DAC output will become indeterminate.

SPECIAL FEATURES
Configuration Bits
Note 1: This data sheet summarizes the features
of the dsPIC33FJ06GS001/101A/102A/
202A and dsPIC33FJ09GS302 devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 24. “Programming and Diagnostics” (DS70207) and Section 25.
“Device Configuration” (DS70194)
in the “dsPIC33F/PIC24H Family
Reference Manual”, which are available from the Microchip web site
(www.microchip.com).
The configuration bytes are implemented as volatile
memory. This means that configuration data must be
programmed each time the device is powered up. Configuration data is stored in the words at the top of the
on-chip program memory space, known as the Flash
Configuration Words. Their specific locations are
shown in Table 22-1 and Table 22-2. The configuration
data is automatically loaded from the Flash Configuration Words to the proper Configuration registers during
device Resets.
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.
When creating applications for these devices, users
should always specifically allocate the location of the
Flash Configuration byte for configuration data. This is
to make certain that program code is not stored in this
address when the code is compiled.
The dsPIC33FJ06GS001/101A/102A/202A and
dsPIC33FJ09GS302 family of devices includes several
features that are included to maximize application
flexibility and reliability, and minimize cost through
elimination of external components. These features are:
•
•
•
•
•
•
•
22.1
Flexible Configuration
Watchdog Timer (WDT)
Code Protection
JTAG Boundary Scan Interface
In-Circuit Serial Programming™ (ICSP™)
In-Circuit Emulation
Brown-out Reset (BOR)
Note:
Configuration data is reloaded on all types
of device Resets.
The upper 2 bytes of all Flash Configuration Words in
program memory should always be ‘1111 1111 1111
1111’. This makes them appear to be NOP instructions
in the remote event that their locations are ever executed by accident. Since Configuration bits are not
implemented in the corresponding locations, writing
‘1’s to these locations has no effect on device
operation.
Note:
Performing a page erase operation on the
last page of program memory, clears the
Flash Configuration Words, enabling code
protection as a result. Therefore, users
should avoid performing page erase
operations on the last page of program
memory
The Configuration Flash Byte maps are shown in
Table 22-1 and Table 22-2.
The Constant Current Source Calibration register is
shown in Register 22-1.

22.2
On-Chip Voltage Regulator
The 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 incorporate
an on-chip regulator that allows the device to run its core
logic from VDD.
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 22-1). This helps to maintain the stability of the
regulator. The recommended value for the filter
capacitor is provided in Table 25-13, located in
Section 25.1 “DC Characteristics”.
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.

22.3
Brown-out Reset (BOR)
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).
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>).
If an oscillator mode is selected, the BOR activates the
Oscillator Start-up Timer (OST). The system clock is
held until the OST expires. If the PLL is used, the clock
is held until the LOCK bit (OSCCON<5>) is ‘1’.
Concurrently, the 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.

22.4
Watchdog Timer (WDT)
22.4.2
The Watchdog Timer (WDT) is driven by the LPRC
oscillator. When the WDT is enabled, the clock source is
also enabled.
22.4.1
PRESCALER/POSTSCALER
The nominal WDT clock source from LPRC is 32 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
(FWDT<4>). With a 32 kHz input, the prescaler yields
a nominal WDT time-out period (TWDT) 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.
The WDT, prescaler and postscaler are reset:
• 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<2:0> 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
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 device will wake the device and code execution will
continue from where the PWRSAV instruction was
executed. The corresponding SLEEP bit (RCON<3>)
or IDLE bit (RCON<2>) will need to be cleared in
software after the device wakes up.
22.4.3
ENABLING WDT
The WDT is enabled or disabled by the FWDTEN
Configuration bit in the FWDT Configuration register
(FWDT<7>). When the FWDTEN Configuration bit is
set, the WDT is always enabled.
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.
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.
The CLRWDT and PWRSAV instructions
clear the prescaler and postscaler counts
when executed.

can be serially programmed while in the end
application circuit. This is done with two lines for clock
and data, and three other lines for power, ground and
the programming sequence. Serial programming
allows customers to manufacture boards with
unprogrammed devices and then program the 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

(DS70152) for details about In-Circuit Serial
Programming (ICSP™).
• PGEC1 and PGED1
• PGEC2 and PGED2
• PGEC3 and PGED3
To use the in-circuit debugger function of the device,
the design must implement ICSP connections to

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 instruction set for this family of dsPIC33F devices
is identical to the instruction set for dsPIC30F devices.
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 23-1 shows the general symbols used in
describing the instructions.
The dsPIC33F instruction set summary in Table 23-2
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 simple rotate/
shift instructions) have two operands:
• 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’

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 23-1:
(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.
Note:
For more details on the instruction set,
refer to the “16-Bit MCU and DSC
Programmer’s
Reference
Manual”
(DS70157).

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

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, OSC1 is driven with external square wave from rail-to-rail
• 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 (PMDx bits are
all zeroed)
• CPU is executing while(1) statement
These parameters are characterized but not tested in manufacturing.

rail-to-rail
• 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

• All peripheral modules are disabled (PMDx bits are all ‘1’s)
• VREGS bit (RCON<8>) = 1 (i.e., core regulator is set to standby while the device is in Sleep mode)
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.

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.
Data for this parameter is Preliminary. This parameter is characterized, but not tested in manufacturing.

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.

IMPLIED, WRITTEN OR ORAL, STATUTORY OR
OTHERWISE, RELATED TO THE INFORMATION,
INCLUDING BUT NOT LIMITED TO ITS CONDITION,
