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.

TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via Email at [email protected] or fax the Reader Response Form in the back of this data sheet to (480) 792-4150. We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000A is version A of document DS30000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current

The PIC24HJXXXGPX06A/X08A/X10A device family
includes devices with different pin counts (64 and 100
pins), different program memory sizes (64 Kbytes, 128
Kbytes and 256 Kbytes) and different RAM sizes (8
Kbytes and 16 Kbytes).
© 2011 Microchip Technology Inc.
This makes these families suitable for a wide variety of
high-performance digital signal control applications.
The devices are pin compatible with the dsPIC33F family of devices, and also share a very high degree of
compatibility with the dsPIC30F family devices. This
allows easy migration between device families as may
be necessitated by the specific functionality, computational resource and system cost requirements of the
application.
The PIC24HJXXXGPX06A/X08A/X10A device family
employs a powerful 16-bit architecture, ideal for
applications that rely on high-speed, repetitive
computations, as well as control.
The 17 x 17 multiplier, hardware support for division
operations, multi-bit data shifter, a large array of 16-bit
working registers and a wide variety of data addressing
modes,
together
provide
the
PIC24HJXXXGPX06A/X08A/X10A Central Processing
Unit (CPU) with extensive mathematical processing
capability. Flexible and deterministic interrupt handling,
coupled with a powerful array of peripherals, renders
the PIC24HJXXXGPX06A/X08A/X10A devices suitable for control applications. Further, Direct Memory
Access (DMA) enables overhead-free transfer of data
between several peripherals and a dedicated DMA
RAM. Reliable, field programmable Flash program
memory ensures scalability of applications that use
PIC24HJXXXGPX06A/X08A/X10A devices.

GUIDELINES FOR GETTING
STARTED WITH 16-BIT
MICROCONTROLLERS
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
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”. Please see
the
Microchip
web
site
(www.microchip.com) for the latest
dsPIC33F/PIC24H Family Reference
Manual sections.
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
PIC24HJXXXGPX06A/X08A/X10A family of 16-bit
Microcontrollers (MCUs) 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 “CPU Logic Filter Capacitor
Connection (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”)
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.
Additionally, the following pins may be required:
• VREF+/VREF- pins used when external voltage
reference for ADC module is implemented
Note:
The AVDD and AVSS pins must be
connected independent of the ADC
voltage reference source.

Master Clear (MCLR) Pin
The MCLR pin provides for two specific device
functions:
• Device Reset
• Device programming and debugging
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.

TANK CAPACITORS
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 MCUs 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.
2.3
CPU Logic Filter Capacitor
Connection (VCAP)
A low-ESR (< 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 24.0
“Electrical
Characteristics”
for
additional
information.

Note 1:
R ≤ 10 kΩ is recommended. A suggested
starting value is 10 kΩ. Ensure that the
MCLR pin VIH and VIL specifications are met.
2:
R1 ≤ 470Ω 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.
The placement of this capacitor should be close to the
VCAP. It is recommended that the trace length not
exceed one-quarter inch (6 mm). Refer to Section 21.2
“On-Chip Voltage Regulator” for details.

PIC24HJXXXGPX06A/X08A/X10A
2.5
ICSP Pins
The PGECx and PGEDx pins are used for In-Circuit
Serial Programming™ (ICSP™) and debugging purposes. It is recommended to keep the trace length
between the ICSP connector and the ICSP pins on the
device as short as possible. If the ICSP connector is
expected to experience an ESD event, a series resistor
is recommended, with the value in the range of a few
tens of Ohms, not to exceed 100 Ohms.
Pull-up resistors, series diodes, and capacitors on the
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger communications to the device. If such discrete components are
an application requirement, they should be removed
from the circuit during programming and debugging.
Alternatively, refer to the AC/DC characteristics and
timing requirements information in the respective
device Flash programming specification for information
on capacitive loading limits and pin input voltage high
(VIH) and input low (VIL) requirements.
Ensure that the “Communication Channel Select” (i.e.,
PGECx/PGEDx pins) programmed into the device
matches the physical connections for the ICSP to
MPLAB® ICD 2, MPLAB ICD 3 or MPLAB REAL ICE™.
For more information on ICD 2, ICD 3 and REAL ICE
connection requirements, refer to the following
documents that are available on the Microchip website.

Guide” DS51331

2.6
External Oscillator Pins
Many MCUs have options for at least two oscillators: a
high-frequency primary oscillator and a low-frequency
secondary oscillator (refer to Section 9.0 “Oscillator
Configuration” for details).
The oscillator circuit should be placed on the same
side of the board as the device. Also, place the
oscillator circuit close to the respective oscillator pins,
not exceeding one-half inch (12 mm) distance
between them. The load capacitors should be placed
next to the oscillator itself, on the same side of the
board. Use a grounded copper pour around the
oscillator circuit to isolate them from surrounding
circuits. The grounded copper pour should be routed
directly to the MCU ground. Do not run any signal
traces or power traces inside the ground pour. Also, if
using a two-sided board, avoid any traces on the
other side of the board where the crystal is placed. A
suggested layout is shown in Figure 2-3.

2.7
Oscillator Value Conditions on
Device Start-up
If the PLL of the target device is enabled and
configured for the device start-up oscillator, the
maximum oscillator source frequency must be limited
to ≤8 MHz for start-up with PLL enabled to comply with
device PLL start-up conditions. This means that if the
external oscillator frequency is outside this range, the
application must start-up in the FRC mode first. The
default PLL settings after a POR with an oscillator
frequency outside this range will violate the device
operating speed.
Once the device powers up, the application firmware
can initialize the PLL SFRs, CLKDIV and PLLDBF to a
suitable value, and then perform a clock switch to the
Oscillator + PLL clock source. Note that clock switching
must be enabled in the device Configuration word.
2.8
Configuration of Analog and
Digital Pins During ICSP
Operations
If MPLAB ICD 2, ICD 3 or REAL ICE is selected as a
debugger, it automatically initializes all of the A/D input
pins (ANx) as “digital” pins, by setting all bits in the
AD1PCFGL register.
The bits in this register that correspond to the A/D pins
that are initialized by MPLAB ICD 2, ICD 3, or REAL
ICE, must not be cleared by the user application
firmware; otherwise, communication errors will result
between the debugger and the device.
If your application needs to use certain A/D pins as
analog input pins during the debug session, the user
application must clear the corresponding bits in the
AD1PCFGL register during initialization of the ADC
module.
When MPLAB ICD 2, ICD 3 or REAL ICE is used as a
programmer, the user application firmware must
correctly configure the AD1PCFGL register. Automatic
initialization of this register is only done during
debugger operation. Failure to correctly configure the
register(s) will result in all A/D 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 the unused pins.

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 PIC24HJXXXGPX06A/X08A/X10A CPU module
has a 16-bit (data) modified Harvard architecture with an
enhanced instruction set and addressing modes. 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 by 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, single-cycle program loop constructs are
supported using the REPEAT instruction, which is
interruptible at any point.
3.1
Data Addressing Overview
The data space can be linearly addressed as 32K words
or 64 Kbytes using an Address Generation Unit (AGU).
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.
The data space also includes 2 Kbytes of DMA RAM,
which is primarily used for DMA data transfers, but may
be used as general purpose RAM.
3.2
Special MCU Features
The PIC24HJXXXGPX06A/X08A/X10A features a
17-bit by 17-bit, single-cycle multiplier. 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 makes mixed-sign
multiplication possible.
The PIC24HJXXXGPX06A/X08A/X10A supports 16/16
and 32/16 integer divide operations. 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 multi-bit data shifter is used to perform up to a 16-bit,
left or right shift in a single cycle.
The PIC24HJXXXGPX06A/X08A/X10A 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 16th working
register (W15) operates as a software Stack Pointer (SP)
for interrupts and calls.
The PIC24HJXXXGPX06A/X08A/X10A instruction set
includes many addressing modes and is designed for
optimum C compiler efficiency. For most instructions,
the PIC24HJXXXGPX06A/X08A/X10A is capable of
executing a data (or program data) memory read, a
working register (data) read, a data memory write and
a program (instruction) memory read per instruction
cycle. As a result, three parameter instructions can be
supported, allowing A + B = C operations to be
executed in a single cycle.

3.4
Arithmetic Logic Unit (ALU)
The PIC24HJXXXGPX06A/X08A/X10A 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 may 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
PIC24HJXXXGPX06A/X08A/X10A
CPU
incorporates hardware support for both multiplication
and division. This includes a dedicated hardware
multiplier and support hardware for 16-bit divisor
division.
3.4.1
MULTIPLIER
3.4.2
DIVIDER
The divide block supports 32-bit/16-bit and 16-bit/16-bit
signed and unsigned integer divide operations with the
following data sizes:
•
•
•
•
32-bit signed/16-bit signed divide
32-bit unsigned/16-bit unsigned divide
16-bit signed/16-bit signed divide
16-bit unsigned/16-bit unsigned divide
The quotient for all divide instructions ends up in W0
and the remainder in W1. Sixteen-bit signed and
unsigned DIV instructions can specify any W register
for both the 16-bit divisor (Wn) and any W register
(aligned) pair (W(m + 1):Wm) for the 32-bit dividend.
The divide algorithm takes one cycle per bit of divisor,
so both 32-bit/16-bit and 16-bit/16-bit instructions take
the same number of cycles to execute.
3.4.3
MULTI-BIT DATA SHIFTER
The multi-bit data shifter is capable of performing 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 a
working register or a memory location.
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.
Using the high-speed 17-bit x 17-bit multiplier, the ALU
supports unsigned, signed or mixed-sign operation in
several multiplication modes:
•
•
•
•
•
•
•
16-bit x 16-bit signed
16-bit x 16-bit unsigned
16-bit signed x 5-bit (literal) unsigned
16-bit unsigned x 16-bit unsigned
16-bit unsigned x 5-bit (literal) unsigned
16-bit unsigned x 16-bit signed
8-bit unsigned x 8-bit unsigned

4.1
This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, it is not
intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 3.
“Data Memory” (DS70237) of the
“dsPIC33F/PIC24H Family Reference
Manual”, which is available from the
Microchip website (www.microchip.com).
The PIC24HJXXXGPX06A/X08A/X10A architecture
features separate program and data memory spaces
and buses. This architecture also allows the direct
access of program memory from the data space during
code execution.
FIGURE 4-1:
The program address memory space of the
PIC24HJXXXGPX06A/X08A/X10A devices is 4M
instructions. The space is addressable by a 24-bit value
derived from either the 23-bit Program Counter (PC)
during program execution, or from table operation or
data space remapping as described in Section 4.4
“Interfacing Program and Data Memory Spaces”.
User access to the program memory space is restricted
to the lower half of the address range (0x000000 to
0x7FFFFF). The exception is the use of TBLRD/TBLWT
operations, which use TBLPAG<7> to permit access to
the Configuration bits and Device ID sections of the
configuration memory space.
Memory maps for the PIC24HJXXXGPX06A/X08A/

PROGRAM MEMORY
ORGANIZATION
4.1.2
All PIC24HJXXXGPX06A/X08A/X10A 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 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 (Figure 4-2).
PIC24HJXXXGPX06A/X08A/X10A devices also have
two interrupt vector tables, located from 0x000004 to
0x0000FF and 0x000100 to 0x0001FF. These vector
tables allow each of the many 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 code execution. This
arrangement also provides compatibility with data
memory space addressing and makes it possible to
access data in the program memory space.

4.2
Data Address Space
The PIC24HJXXXGPX06A/X08A/X10A 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. Data memory maps of devices with different RAM sizes are
shown in Figure 4-3 and Figure 4-4.
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 4.4.3 “Reading Data from
Program Memory Using Program Space Visibility”).
PIC24HJXXXGPX06A/X08A/X10A devices implement
up to 16 Kbytes of data memory. Should an EA point to
a location outside of this area, an all-zero word or byte
will be returned.
4.2.1
DATA SPACE WIDTH
The data memory space is organized in byte addressable, 16-bit wide blocks. Data is aligned in data
memory and registers as 16-bit words, but all data
space EAs resolve to bytes. The Least Significant
Bytes of each word have even addresses, while the
Most Significant Bytes 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 PIC24HJXXXGPX06A/X08A/X10A
instruction set supports both word and byte operations.
As a consequence of byte accessibility, all effective
address calculations are internally scaled to step
through word-aligned memory. For example, the core
recognizes that Post-Modified Register Indirect
Addressing mode [Ws++] will result 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 Least Significant bit (LSb)
of any EA to determine which byte to select. The
selected byte is placed onto the Least Significant Byte
(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 which matches the byte
address.
© 2011 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 it occurred on a
write, the instruction will be executed but the write does
not occur. In either case, a trap is then executed, allowing the system and/or user 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
(MSB) is not modified.
A sign-extend instruction (SE) is provided to allow
users to translate 8-bit signed data to 16-bit signed
values. Alternatively, for 16-bit unsigned data, users
can clear the Most Significant Byte 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
PIC24HJXXXGPX06A/X08A/X10A 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’. A complete listing of implemented
SFRs, including their addresses, is shown in Table 4-1
through Table 4-33.
Note:
4.2.4
The actual set of peripheral features and
interrupts varies by the device. Please
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.

DMA RAM
Every
PIC24HJXXXGPX06A/X08A/X10A
device
contains 2 Kbytes of dual ported DMA RAM located at
the end of data space. Memory locations in the DMA
RAM space are accessible simultaneously by the CPU
and the DMA controller module. DMA RAM is utilized by
the DMA controller to store data to be transferred to
various peripherals using DMA, as well as data
0xFFFE
transferred from various peripherals using DMA. The
DMA RAM can be accessed by the DMA controller
without having to steal cycles from the CPU.
When the CPU and the DMA controller attempt to
concurrently write to the same DMA RAM location, the
hardware ensures that the CPU is given precedence in
accessing the DMA RAM location. Therefore, the DMA
RAM provides a reliable means of transferring DMA
data without ever having to stall the CPU.
Note:
© 2011 Microchip Technology Inc.
DMA RAM can be used for general
purpose data storage if the DMA function
is not required in an application.

PIC24HJXXXGPX06A/X08A/X10A
4.2.6
4.2.7
SOFTWARE STACK
In addition to its use as a working register, the W15
register in the PIC24HJXXXGPX06A/X08A/X10A
devices is also used as a software Stack Pointer. The
Stack Pointer always points to the first available free
word and grows from lower to higher addresses. It predecrements for stack pops and post-increments for
stack pushes, as shown in Figure 4-5. For a PC push
during any CALL instruction, the MSB of the PC is zeroextended 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. Thus, for example, if it is
desirable to cause a stack error trap when the stack
grows beyond address 0x2000 in RAM, initialize the
SPLIM with the value 0x1FFE.
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.

The PIC24H product family supports Data RAM protection features that enable segments of RAM to be
protected when used in conjunction with Boot and
Secure Code Segment Security. BSRAM (Secure RAM
segment for BS) is accessible only from the Boot Segment Flash code, when enabled. SSRAM (Secure
RAM segment for RAM) is accessible only from the
Secure Segment Flash code, when enabled. See
Table 4-1 for an overview of the BSRAM and SSRAM
SFRs.
4.3
Instruction Addressing Modes
The addressing modes in Table 4-34 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 are
somewhat different from those in the other instruction
types.
4.3.1
FILE REGISTER INSTRUCTIONS
Most file register instructions use a 13-bit address field
(f) to directly address data present in the first 8192
bytes of data memory (Near Data Space). Most file
register instructions employ a working register, W0,
which is denoted as WREG in these instructions. The
destination is typically either the same file register or
WREG (with the exception of the MUL instruction),
which writes the result to a register or register pair. The
MOV instruction allows additional flexibility and can
access the entire data space.
4.3.2
MCU INSTRUCTIONS
The 3-operand MCU instructions are of the form:
Operand 3 = Operand 1 <function> Operand 2
where:
Operand 1 is always a working register (i.e., 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:
W15 (before CALL)
W15 (after CALL)
POP : [--W15]
PUSH : [W15++]
•
•
•
•
•
Register Direct
Register Indirect
Register Indirect Post-Modified
Register Indirect Pre-Modified
5-bit or 10-bit Literal
Note:
© 2011 Microchip Technology Inc.
DATA RAM PROTECTION FEATURE
Not all instructions support all the
addressing
modes
given
above.
Individual instructions may support
different subsets of these addressing
modes.
DS70592C-page 57
PIC24HJXXXGPX06A/X08A/X10A
TABLE 4-34:
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 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 Indirect with Literal Offset
4.3.3
The sum of Wn and a literal forms the EA.
MOVE INSTRUCTIONS
Move instructions provide a greater degree of addressing flexibility than other instructions. In addition to the
Addressing modes supported by most MCU instructions, move 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 between both source and
destination (but typically only used by
one).
In summary, the following Addressing modes are
supported by move instructions:
•
•
•
•
•
•
•
•
Register Direct
Register Indirect
Register Indirect Post-modified
Register Indirect Pre-modified
Register Indirect with Register Offset (Indexed)
Register Indirect with Literal Offset
8-bit Literal
16-bit Literal
Note:
4.3.4
Not all instructions support all the
Addressing
modes
given
above.
Individual instructions may support
different subsets of these Addressing
modes.
OTHER INSTRUCTIONS
Besides the various addressing modes outlined above,
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, the source of an operand or result is implied by the opcode itself. Certain
operations, such as NOP, do not have any operands.

The PIC24HJXXXGPX06A/X08A/X10A 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.
Aside
from
normal
execution,
the
PIC24HJXXXGPX06A/X08A/X10A 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)
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 from time to time. 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. It can only
access the least significant word of the program word.
4.4.1
ADDRESSING PROGRAM SPACE
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.
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).

PIC24HJXXXGPX06A/X08A/X10A
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 4-35:
Table 4-35 and Figure 4-6 show how the program EA is
created for table operations and remapping accesses
from the data EA. Here, P<23:0> refers to a program
space word, whereas D<15:0> refers to a data space
word.

DATA ACCESS FROM PROGRAM
MEMORY USING TABLE
INSTRUCTIONS
2.
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,
word wide address spaces, residing side by side, each
with the same address range. TBLRDL and TBLWTL
access the space which contains the least significant
data word and TBLRDH and TBLWTH access the space
which 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.
1.
TBLRDL (Table Read Low): In Word mode, it
maps the lower word of the program space
location (P<15:0>) to a data address (D<15:0>).
TBLRDH (Table Read High): In Word mode, it
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, it maps the upper or lower byte of
the program word to D<7:0> of the data
address, as above. Note that the data will
always be ‘0’ when the upper ‘phantom’ byte is
selected (Byte Select = 1).
In a similar fashion, 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.
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’.

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 of stored constant data from the data space without the need to use
special instructions (i.e., TBLRDL/H).
Program space access through the data space occurs
if the Most Significant bit of the data space EA is ‘1’ and
program space visibility is enabled by setting the PSV
bit in the Core Control register (CORCON<2>). The
location of the program memory space to be mapped
into the data space is determined by the Program
Space Visibility Page register (PSVPAG). This 8-bit
register defines any one of 256 possible pages of
16K words in program space. In effect, PSVPAG functions as the upper 8 bits of the program memory
address, with the 15 bits of the EA functioning as the
lower bits. Note that 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 an additional 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 4-8), only the lower 16 bits of the
FIGURE 4-8:
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, which are executed inside
a REPEAT loop, there will be some instances that
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 accessing data, using PSV, to execute in a
single cycle.

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

intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section
5. “Flash Programming” (DS70228) of
the “dsPIC33F/PIC24H Family Reference Manual”, which is available from the
Microchip website (www.microchip.com).
RTSP is accomplished using TBLRD (table read) and
TBLWT (table write) instructions. With RTSP, the user
can write program memory data either in blocks or
‘rows’ of 64 instructions (192 bytes) at a time, or single
instructions and erase program memory in blocks or
‘pages’ of 512 instructions (1536 bytes) at a time.
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
5.1
The PIC24HJXXXGPX06A/X08A/X10A 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.

FIGURE 5-1:
Table Instructions and Flash
Programming
Regardless of the method used, all programming of
Flash memory is done with the table read and table
write instructions. These allow direct read and write
access to the program memory space from the data
memory while the device is in normal operating mode.
The 24-bit target address in the program memory is
formed using bits<7:0> of the TBLPAG register and the
Effective Address (EA) from a W register specified in
the table instruction, as shown in Figure 5-1.
The TBLRDL and the TBLWTL instructions are used to
read or write to bits<15:0> of program memory.
TBLRDL and TBLWTL can access program memory in
both Word and Byte modes.
The TBLRDH and TBLWTH instructions are used to read
or write to bits<23:16> of program memory. TBLRDH
and TBLWTH can also access program memory in Word
or Byte mode.

RTSP Operation
The PIC24HJXXXGPX06A/X08A/X10A Flash program
memory array is organized into rows of 64 instructions
or 192 bytes. RTSP allows the user 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 24-12 displays 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 in sequential order. 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 24-19) and the value of the FRC Oscillator
Tuning register (see Register 9-4). Use the following
formula to calculate the minimum and maximum values
for the Row Write Time, Page Erase Time and Word
Write Cycle Time parameters (see Table 24-12).
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 9-4) are set to ‘b111111, the minimum row
write time is equal to Equation 5-2.
EQUATION 5-2:
MINIMUM ROW WRITE
TIME
11064 Cycles
T RW = ------------------------------------------------------------------------------------------------ = 1.435ms
7.37 MHz × ( 1 + 0.05 ) × ( 1 – 0.00375 )
The maximum row write time is equal to Equation 5-3.

11064 Cycles
T RW = ------------------------------------------------------------------------------------------------ = 1.586ms

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
The two SFRs that are used to read and write the
program Flash memory are:
• NVMCON
• 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 must consecutively write 0x55 and 0xAA to the
NVMKEY register. Refer to Section 5.3 “Programming
Operations” for further details.

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

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

dsPIC30F/33F devices in which the erase
page was selected using a dedicated pair
of registers (NVMADRU and NVMADR).

2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The Reset module combines all Reset sources and
controls the device Master Reset Signal, SYSRST. The
following is a list of device Reset sources:
•
•
•

BOR: Brown-out Reset
MCLR: Master Clear Pin Reset
SWR: RESET Instruction
WDT: Watchdog Timer Reset
TRAPR: Trap Conflict Reset

Register Reset
FIGURE 6-1:
Any active source of Reset will make the SYSRST signal active. Many registers associated with the CPU and
peripherals are forced to a known Reset state. Most
registers are unaffected by a Reset; their status is
unknown on POR and unchanged by all other Resets.
Note:
Refer to the specific peripheral or CPU
section of this manual for register Reset
states.
All types of device Reset will set a corresponding status
bit in the RCON register to indicate the type of Reset
(see Register 6-1). A POR will clear all bits, except for
the POR bit (RCON<0>), that are set. The user 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 will be meaningful.

SWDTEN bit setting.
For PIC24HJ256GPX06A/X08A/X10A devices, this bit is unimplemented and reads back programmed
value.

Clock Source Selection at Reset
If clock switching is enabled, the system clock source at
device Reset is chosen, as shown in Table 6-2. If clock
switching is disabled, the system clock source is always
selected according to the oscillator Configuration bits.

Device Reset Times
The Reset times for various types of device Reset are
summarized in Table 6-3. The system Reset signal is
released after the POR and PWRT delay times expire.
The time at which the device actually begins to execute
code also depends on the system oscillator delays,
which include the Oscillator Start-up Timer (OST) and
the PLL lock time. The OST and PLL lock times occur
in parallel with the applicable reset delay times.
The FSCM delay determines the time at which the
FSCM begins to monitor the system clock source after
the reset signal is released.

TPOR = Power-on Reset delay (10 μs nominal).
TSTARTUP = Conditional POR delay of 20 μs nominal (if on-chip regulator is enabled) or 64 ms nominal
Power-up Timer delay (if regulator is disabled). TSTARTUP is also applied to all returns from powered-down
states, including waking from Sleep mode, only if the regulator is enabled.
TRST = Internal state Reset time (20 μs nominal).
TOST = Oscillator Start-up Timer. A 10-bit counter counts 1024 oscillator periods before releasing the
oscillator clock to the system.
TLOCK = PLL lock time (20 μs nominal).
TFSCM = Fail-Safe Clock Monitor delay (100 μs nominal).
POR AND LONG OSCILLATOR
START-UP TIMES
The oscillator start-up circuitry and its associated delay
timers are not linked to the device Reset delays that
occur at power-up. Some crystal circuits (especially
low-frequency crystals) have a relatively long start-up
time. Therefore, one or more of the following conditions
is possible after the Reset signal is released:
• The oscillator circuit has not begun to oscillate
• The Oscillator Start-up Timer has not expired (if a
crystal oscillator is used)
• The PLL has not achieved a lock (if PLL is used)
The device will not begin to execute code until a valid
clock source has been released to the system. Therefore, the oscillator and PLL start-up delays must be
considered when the Reset delay time must be known.
6.2.2
FAIL-SAFE CLOCK MONITOR
(FSCM) AND DEVICE RESETS
If the FSCM is enabled, it begins to monitor the system
clock source when the Reset signal is released. If a
valid clock source is not available at this time, the
device automatically switches to the FRC oscillator and
the user can switch to the desired crystal oscillator in
the Trap Service Routine.
DS70592C-page 72
6.2.2.1
FSCM Delay for Crystal and PLL
Clock Sources
When the system clock source is provided by a crystal
oscillator and/or the PLL, a small delay, TFSCM, is automatically inserted after the POR and PWRT delay
times. The FSCM does not begin to monitor the system
clock source until this delay expires. The FSCM delay
time is nominally 500 μs and provides additional time
for the oscillator and/or PLL to stabilize. In most cases,
the FSCM delay prevents an oscillator failure trap at a
device Reset when the PWRT is disabled.
6.3
Special Function Register Reset
States
Most of the Special Function Registers (SFRs) associated with the CPU and peripherals are reset to a
particular value at a device Reset. The SFRs are
grouped by their peripheral or CPU function and their
Reset values are specified in each section of this
manual.
The Reset value for each SFR does not depend on the
type of Reset, with the exception of two registers. The
Reset value for the Reset Control register, RCON,
depends on the type of device Reset. The Reset value
for the Oscillator Control register, OSCCON, depends
on the type of Reset and the programmed values of the
oscillator Configuration bits in the FOSC Configuration
register.

INTERRUPT CONTROLLER
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, it is not
intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 6. “Interrupts” (DS70224) of
the
“dsPIC33F/PIC24H
Family
Reference Manual”, which is available
from
the
Microchip
website
(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 PIC24HJXXXGPX06A/X08A/X10A interrupt controller reduces the numerous peripheral interrupt
request signals to a single interrupt request signal to
the PIC24HJXXXGPX06A/X08A/X10A CPU. It has the
following features:
•
•
•
•
Up to 8 processor exceptions and software traps
7 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
7.1.1
ALTERNATE VECTOR TABLE
The Alternate Interrupt Vector Table (AIVT) is located
after the IVT, as shown in Figure 7-1. Access to the
AIVT is provided by the ALTIVT control bit
(INTCON2<15>). If the ALTIVT bit is set, all interrupt
and exception processes use the alternate vectors
instead of the default vectors. The alternate vectors are
organized in the same manner as the default vectors.
The AIVT supports debugging by providing a means to
switch between an application and a support environment without requiring the interrupt vectors to be
reprogrammed. This feature also enables switching
between applications for evaluation of different software algorithms at run time. If the AIVT is not needed,
the AIVT should be programmed with the same
addresses used in the IVT.
7.2
Reset Sequence
A device Reset is not a true exception because the
interrupt controller is not involved in the Reset process.
The PIC24HJXXXGPX06A/X08A/X10A 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. The user programs a GOTO instruction at the Reset address which
redirects 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 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
8 nonmaskable trap vectors plus up to 118 sources of
interrupt. In general, each interrupt source has its own
vector. Each interrupt vector contains a 24-bit wide
address. The value programmed into each interrupt
vector location is the starting address of the associated
Interrupt Service Routine (ISR).
Interrupt vectors are prioritized in terms of their natural
priority; this priority is linked to their position in the
vector table. All other things being equal, lower
addresses have a higher natural priority. For example,
the interrupt associated with vector 0 will take priority
over interrupts at any other vector address.
PIC24HJXXXGPX06A/X08A/X10A devices implement
up to 61 unique interrupts and 5 nonmaskable traps.
These are summarized in Table 7-1 and Table 7-2.

Interrupt Control and Status
Registers
PIC24HJXXXGPX06A/X08A/X10A devices implement
a total of 30 registers for the interrupt controller:
•
•
•
•
•
•
INTCON1
INTCON2
IFS0 through IFS4
IEC0 through IEC4
IPC0 through IPC17
INTTREG
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.
The IFS 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.
The IEC registers maintain all of the interrupt enable
bits. These control bits are used to individually enable
interrupts from the peripherals or external signals.
The IPC registers are used to set the interrupt priority
level for each source of interrupt. Each user interrupt
source can be assigned to one of eight priority levels.
The INTTREG register contains the associated interrupt vector number and the new CPU interrupt priority
level, which are latched into 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 in IEC0<0>, and the INT0IP
bits in the first position of IPC0 (IPC0<2:0>).
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>, also 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 7-32.

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

Interrupt Setup Procedures
7.4.1
INITIALIZATION
To configure an interrupt source:
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 may 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
7.4.3
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
All user interrupts can be disabled using the following
procedure:
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 0x0E with SRL.
To enable user interrupts, the POP instruction may be
used to restore the previous SR value.
Note that only user interrupts with a priority level of 7 or
less 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 that is used to declare an ISR and initialize
the IVT with the correct vector address will depend on
the programming language (i.e., C or assembler) and
the language development toolsuite that is used to
develop the application. In general, the user must clear
the interrupt flag in the appropriate IFSx register for the
source of interrupt that the ISR handles. Otherwise, the
ISR will be re-entered immediately after exiting the
routine. If the ISR is coded in assembly language, it
must be terminated using a RETFIE instruction to
unstack the saved PC value, SRL value and old CPU
priority level.

DIRECT MEMORY ACCESS
(DMA)
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, it is not
intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section
22. “Direct Memory Access (DMA)”
(DS70223) of the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip website
(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.
Direct Memory Access (DMA) is a very efficient
mechanism of copying data between peripheral SFRs
(e.g., UART Receive register, Input Capture 1 buffer),
and buffers or variables stored in RAM, with minimal
CPU intervention. The DMA controller can
automatically copy entire blocks of data without
requiring the user software to read or write the
peripheral Special Function Registers (SFRs) every
time a peripheral interrupt occurs. The DMA controller
uses a dedicated bus for data transfers and, therefore,
does not steal cycles from the code execution flow of
the CPU. To exploit the DMA capability, the
corresponding user buffers or variables must be
located in DMA RAM.
The PIC24HJXXXGPX06A/X08A/X10A peripherals
that can utilize DMA are listed in Table 8-1 along with
their associated Interrupt Request (IRQ) numbers.

The DMA controller features eight identical data
transfer channels.
Each channel has its own set of control and status
registers. Each DMA channel can be configured to
copy data either from buffers stored in dual port DMA
RAM to peripheral SFRs, or from peripheral SFRs to
buffers in DMA RAM.
The DMA controller supports the following features:
• Word or byte sized data transfers
• Transfers from peripheral to DMA RAM or DMA
RAM to peripheral
• Indirect Addressing of DMA RAM locations with or
without automatic post-increment
• Peripheral Indirect Addressing – In some
peripherals, the DMA RAM read/write addresses
may be partially derived from the peripheral
• One-Shot Block Transfers – Terminating DMA
transfer after one block transfer
• Continuous Block Transfers – Reloading DMA RAM
buffer start address after every block transfer is
complete
• Ping-Pong Mode – Switching between two DMA
RAM start addresses between successive block
transfers, thereby filling two buffers alternately
• Automatic or manual initiation of block transfers
• Each channel can select from 19 possible sources
of data sources or destinations
For each DMA channel, a DMA interrupt request is
generated when a block transfer is complete. Alternatively, an interrupt can be generated when half of the
block has been filled.

DMAC Registers
Each DMAC Channel x (x = 0, 1, 2, 3, 4, 5, 6 or 7)
contains the following registers:
• A 16-bit DMA Channel Control register
(DMAxCON)
• A 16-bit DMA Channel IRQ Select register
(DMAxREQ)
• A 16-bit DMA RAM Primary Start Address Offset
register (DMAxSTA)
• A 16-bit DMA RAM Secondary Start Address
Offset register (DMAxSTB)
• A 16-bit DMA Peripheral Address register
(DMAxPAD)
• A 10-bit DMA Transfer Count register (DMAxCNT)
An additional pair of status registers, DMACS0 and
DMACS1 are common to all DMAC channels.

9.1.1
SYSTEM CLOCK SOURCES
The FRC (Fast RC) internal oscillator runs at a nominal
frequency of 7.37 MHz. The 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.
(FOSC<1:0>), select the oscillator source that is used at
a Power-on Reset. The FRC primary oscillator is the
default (unprogrammed) selection.
The Configuration bits allow users to choose between
twelve different clock modes, shown in Table 9-1.
The output of the oscillator (or the output of the PLL if
a PLL mode has been selected) FOSC is divided by 2 to
generate the device instruction clock (FCY) and the
peripheral clock time base (FP). FCY defines the
operating speed of the device, and speeds up to 40
MHz are supported by the PIC24HJXXXGPX06A/
X08A/X10A architecture.
Instruction execution speed or device operating
frequency, FCY, is calculated, as shown in
Equation 9-1:
EQUATION 9-1:
OSC
------------F CY = F

The primary oscillator can use one of the following as
its clock source:
• XT (Crystal): Crystals and ceramic resonators in
the range of 3 MHz to 10 MHz. The crystal is connected to the OSC1 and OSC2 pins.
• HS (High-Speed Crystal): Crystals in the range of
10 MHz to 40 MHz. The crystal is connected to
the OSC1 and OSC2 pins.
• EC (External Clock): External clock signal is
directly applied to the OSC1 pin.
The secondary (LP) oscillator is designed for low power
and uses a 32.768 kHz crystal or ceramic resonator.
The LP oscillator uses the SOSCI and SOSCO pins.
The LPRC (Low-Power RC) 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).
The clock signals generated by the FRC and primary
oscillators can be optionally applied to an on-chip
Phase Locked Loop (PLL) to provide a wide range of
output frequencies for device operation. PLL
configuration is described in Section 9.1.3 “PLL
Configuration”.
The FRC frequency depends on the FRC accuracy
(see Table 24-19) and the value of the FRC Oscillator
Tuning register (see Register 9-4).
9.1.2
SYSTEM CLOCK SELECTION
The oscillator source that is 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 21.1 “Configuration Bits” for further details.)

FREQUENCY
9.1.3
PLL CONFIGURATION
The primary oscillator and internal FRC oscillator can
optionally use an on-chip PLL to obtain higher speeds
of operation. The PLL provides a significant amount of
flexibility in selecting the device operating speed. A
block diagram of the PLL is shown in Figure 9-2.
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 to be in the range of 0.8 MHz to 8 MHz.
Since the minimum prescale factor is 2, this implies that
FIN must be chosen to be in the range of 1.6 MHz to 16
MHz. The prescale factor ‘N1’ is selected using the
PLLPRE<4:0> bits (CLKDIV<4:0>).
The PLL Feedback Divisor, selected using the
PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor ‘M’,
by which the input to the VCO is multiplied. This factor
must be selected such that the resulting VCO output
frequency is in the range of 100 MHz to 200 MHz.
The VCO output is further divided by a postscale factor
‘N2’. This factor is selected using the PLLPOST<1:0>
bits (CLKDIV<7:6>). ‘N2’ can be either 2, 4 or 8, and
must be selected such that the PLL output frequency
(FOSC) is in the range of 12.5 MHz to 80 MHz, which
generates device operating speeds of 6.25-40 MIPS.
For a primary oscillator or FRC oscillator, output ‘FIN’,
the PLL output ‘FOSC’ is given by:

EQUATION 9-3:
For example, suppose a 10 MHz crystal is being used,
with “XT with PLL” being the selected oscillator mode.
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.

If PLLPOST<1:0> = 0, then N2 = 2. This provides a
Fosc of 160/2 = 80 MHz. The resultant device operating
speed is 80/2 = 40 MIPS.

9.2
Clock Switching Operation
Applications are free to switch between any of the four
clock sources (Primary, LP, FRC and LPRC) under
software control at any time. To limit the possible side
effects that could result from this flexibility,
PIC24HJXXXGPX06A/X08A/X10A devices have a
safeguard lock built into the switch process.
Note:
9.2.1
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
between the different primary submodes
without reprogramming the device.
2.
If a valid clock switch has been initiated, the
LOCK
(OSCCON<5>)
and
the
CF
(OSCCON<3>) status bits are cleared.
The new oscillator is turned on by the hardware
if it is not currently running. If a crystal oscillator
must be turned on, the hardware waits until the
Oscillator Start-up Timer (OST) expires. If the
new source is using the PLL, the hardware waits
until a PLL lock is detected (LOCK = 1).
The hardware waits for 10 clock cycles from the
new clock source and then performs the clock
switch.
The hardware clears the OSWEN bit to indicate a
successful clock transition. In addition, the NOSC
bit values are transferred to the COSC status bits.
The old clock source is turned off at this time,
with the exception of LPRC (if WDT or FSCM
are enabled) or LP (if LPOSCEN remains set).
3.
4.
5.
6.
ENABLING CLOCK SWITCHING
To enable clock switching, the FCKSM1 Configuration
bit in the Configuration register must be programmed to
‘0’. (Refer to Section 21.1 “Configuration Bits” for
further details.) If the FCKSM1 Configuration bit is
unprogrammed (‘1’), the clock switching function and
Fail-Safe Clock Monitor function are disabled. This is
the default setting.
Note 1: The processor continues to execute code
throughout the clock switching sequence.
Timing sensitive code should not be
executed during this time.
2: Direct clock switches between any primary oscillator mode with PLL and
FRCPLL mode are not permitted. This
applies to clock switches in either direction. In these instances, the application
must switch to FRC mode as a transition
clock source between the two PLL modes.
3: Refer to Section 7. “Oscillator”
(DS70227) in the “dsPIC33F/PIC24H
Family Reference Manual” for details.
The NOSC control bits (OSCCON<10:8>) do not
control the clock selection when clock switching is
disabled. However, the COSC bits (OSCCON<14:12>)
reflect the clock source selected by the FNOSC
Configuration bits.
The OSWEN control bit (OSCCON<0>) has no effect
when clock switching is disabled. It is held at ‘0’ at all
times.
9.2.2
OSCILLATOR SWITCHING SEQUENCE
At a minimum, performing a clock switch requires this
basic sequence:
1.
2.
3.
4.
5.
If
desired,
read
the
COSC
bits
(OSCCON<14:12>) to determine the current
oscillator source.
Perform the unlock sequence to allow a write to
the OSCCON register high byte.
Write the appropriate value to the NOSC control
bits (OSCCON<10:8>) for the new oscillator
source.
Perform the unlock sequence to allow a write to
the OSCCON register low byte.
Set the OSWEN bit to initiate the oscillator
switch.
Once the basic sequence is completed, the system
clock hardware responds automatically as follows:
1.
The clock switching hardware compares the
COSC status bits with the new value of the
NOSC control bits. If they are the same, the
clock switch is a redundant operation. In this
case, the OSWEN bit is cleared automatically
and the clock switch is aborted.

9.3
Fail-Safe Clock Monitor (FSCM)
The Fail-Safe Clock Monitor (FSCM) allows the device
to continue to operate even in the event of an oscillator
failure. The FSCM function is enabled by programming.
If the FSCM function is enabled, the LPRC internal
oscillator runs at all times (except during Sleep mode)
and is not subject to control by the Watchdog Timer.
If an oscillator failure occurs, the FSCM generates a
clock failure trap event and switches the system clock
over to the FRC oscillator. Then the application
program can either attempt to restart the oscillator or
execute a controlled shutdown. The trap can be treated
as a warm Reset by simply loading the Reset address
into the oscillator fail trap vector.
If the PLL multiplier is used to scale the system clock,
the internal FRC is also multiplied by the same factor
on clock failure. Essentially, the device switches to
FRC with PLL on a clock failure.

POWER-SAVING FEATURES
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, it is not
intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 9. “Watchdog Timer and
Power-Saving Modes” (DS70236) of
the
“dsPIC33F/PIC24H
Family
Reference Manual”, which is available
from
the
Microchip
website
(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
PIC24HJXXXGPX06A/X08A/X10A
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.
PIC24HJXXXGPX06A/X08A/X10A
devices
can
manage power consumption in four different ways:
•
•
•
•
Clock frequency
Instruction-based Sleep and Idle modes
Software-controlled Doze mode
Selective peripheral control in software
Combinations of these methods can be used to selectively tailor an application’s power consumption while
still maintaining critical application features, such as
timing-sensitive communications.
10.1
Clock Frequency and Clock
Switching
PIC24HJXXXGPX06A/X08A/X10A 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 bits
(OSCCON<10:8>). The process of changing a system
clock during operation, as well as limitations to the process, are discussed in more detail in Section 9.0
“Oscillator Configuration”.
EXAMPLE 10-1:
10.2
Instruction-Based Power-Saving
Modes
PIC24HJXXXGPX06A/X08A/X10A 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
assembly syntax of the PWRSAV instruction is shown in
Example 10-1.
Note:
SLEEP_MODE and IDLE_MODE are
constants defined in the assembler
include file for the selected device.
Sleep and Idle modes can be exited as a result of an
enabled interrupt, WDT time-out or a device Reset. When
the device exits these modes, it is said to “wake-up”.
10.2.1
SLEEP MODE
Sleep mode has these features:
• 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
during Sleep mode 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 in Sleep mode. This includes items such
as the input change notification on the I/O ports, or
peripherals that use an external clock input. Any
peripheral that requires the system clock source for
its operation is disabled in Sleep mode.
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, the processor restarts with the
same clock source that was active when Sleep mode
was entered.

DS70592C-page 137
PIC24HJXXXGPX06A/X08A/X10A
10.2.2
IDLE MODE
Idle mode has these features:
• The CPU stops executing instructions.
• The WDT is automatically cleared.
• The system clock source remains active. By
default, all peripheral modules continue to operate
normally from the system clock source, but can
also be selectively disabled (see Section 10.4
“Peripheral Module Disable”).
• If the WDT or FSCM is enabled, the LPRC also
remains active.
The device will wake 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, the clock is reapplied to the CPU
and instruction execution will begin (2-4 clock cycles
later), starting with the instruction following the PWRSAV
instruction, or the first instruction in the ISR.
10.2.3
INTERRUPTS COINCIDENT WITH
POWER SAVE INSTRUCTIONS
Any interrupt that coincides with the execution of a
PWRSAV instruction is held off until entry into Sleep or
Idle mode has completed. The device then wakes up
from Sleep or Idle mode.
10.3
Doze Mode
Generally, changing clock speed and invoking one of the
power-saving modes are the preferred strategies for
reducing power consumption. There may be circumstances, however, where this is not 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 may introduce communication errors, while using
a power-saving mode may stop communications
completely.
Doze mode is a simple and effective alternative method
to reduce power consumption while the device is still
executing code. In this mode, the system clock continues to operate from the same source and at the same
speed. Peripheral modules continue to be clocked at
the same speed, while the CPU clock speed is
reduced. Synchronization between the two clock
domains is maintained, allowing the peripherals to
access the SFRs while the CPU executes code at a
slower rate.
DS70592C-page 138
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.
It is also possible to 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. Enabling the automatic
return to full-speed CPU operation on interrupts is
enabled by setting the ROI bit (CLKDIV<15>). By
default, interrupt events have no effect on Doze mode
operation.
For example, suppose the device is operating at
20 MIPS and the CAN module has been configured for
500 kbps based on this device operating speed. If the
device is now placed in Doze mode with a clock
frequency ratio of 1:4, the CAN module continues to
communicate at the required bit rate of 500 kbps, but
the CPU now starts executing instructions at a
frequency of 5 MIPS.
10.4
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 via 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 only enabled 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 1
instruction cycle. Similarly, if a PMD bit is
cleared, the corresponding module is
enabled after a delay of 1 instruction cycle
(assuming the module control registers
are already configured to enable module
operation).

I/O PORTS
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, it is not
intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 10. “I/O Ports” (DS70230) of
the
“dsPIC33F/PIC24H
Family
Reference Manual”, which is available
from
the
Microchip
website
(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.
which a port’s digital output can drive the input of a
peripheral that shares the same pin. Figure 11-1 shows
how ports are shared with other peripherals and the
associated I/O pin to which they are connected.
When a peripheral is enabled and actively driving an
associated pin, the use of the pin as a general purpose
output pin is disabled. The I/O pin may be read, but the
output driver for the parallel port bit will be disabled. If
a peripheral is enabled, but the peripheral is not
actively driving a pin, that pin may 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 a ‘1’, the pin is
then 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.
All of the device pins (except VDD, VSS, MCLR and
OSC1/CLKIN) are shared between the peripherals and
the parallel I/O ports. All I/O input ports feature Schmitt
Trigger inputs for improved noise immunity.
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 pins will read as zeros.
11.1
When a pin is shared with another peripheral or function that is defined as an input only, it is nonetheless
regarded as a dedicated port because there is no other
competing source of outputs. An example is the INT4
pin.
Parallel I/O (PIO) Ports
A parallel I/O port that shares a pin with a peripheral is,
in general, 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
FIGURE 11-1:
Note:
The voltage on a digital input pin can be
between -0.3V to 5.6V.

11.2
Open-Drain Configuration
11.4
In addition to the PORT, LAT and TRIS registers for
data control, some 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 (e.g., 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.
See the “Pin Diagrams” section for the available pins
and their functionality.
11.3
Configuring Analog Port Pins
The use of the ADxPCFGH, ADxPCFGL and TRIS
registers control the operation of the Analog-to-Digital
port pins. The port pins that are desired 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) is converted.
Clearing any bit in the ADxPCFGH or ADxPCFGL register configures the corresponding bit to be an analog
pin. This is also the Reset state of any I/O pin that has
an analog (ANx) function associated with it.
Note:
In devices with two ADC modules, if the
corresponding PCFG bit in either
AD1PCFGH(L) and AD2PCFGH(L) is
cleared, the pin is configured as an analog
input.
When reading the PORT register, all pins configured as
analog input channels will read as cleared (a low level).
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.
11.5
Input Change Notification
The input change notification function of the I/O ports
allows the PIC24HJXXXGPX06A/X08A/X10A devices
to generate interrupt requests to the processor in
response to a change-of-state on selected input pins.
This feature is capable of detecting input
change-of-states even in Sleep mode, when the clocks
are disabled. Depending on the device pin count, there
are up to 24 external signals (CN0 through CN23) that
can be selected (enabled) for generating an interrupt
request on a change-of-state.
There are four control registers associated with the CN
module. The CNEN1 and CNEN2 registers contain the
CN interrupt enable (CNxIE) control bits for each of the
CN input pins. Setting any of these bits enables a CN
interrupt for the corresponding pins.
Each CN pin also has a weak pull-up connected to it.
The pull-ups act as a current source that is connected
to the pin and eliminate the need for external resistors
when push button or keypad devices are connected.
The pull-ups are enabled separately using the CNPU1
and CNPU2 registers, which contain the weak pull-up
enable (CNxPUE) 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 whenever the
port pin is configured as a digital output.
Pins configured as digital inputs will not convert an
analog input. Analog levels on any pin that is defined as
a digital input (including the ANx pins) can cause the
input buffer to consume current that exceeds the
device specifications.
Note:
The voltage on an analog input pin can be
between -0.3V to (VDD + 0.3 V).

TIMER2/3, TIMER4/5, TIMER6/7
AND TIMER8/9
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, it is not
intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section
11. “Timers” (DS70244) of the
“dsPIC33F/PIC24H Family Reference
Manual”, which is available from the
Microchip website (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 Timer2/3, Timer4/5, Timer6/7 and Timer8/9
modules are 32-bit timers, which can also be configured as four independent 16-bit timers with selectable
operating modes.
As a 32-bit timer, Timer2/3, Timer4/5, Timer6/7 and
Timer8/9 operate in three modes:
• Two Independent 16-bit Timers (e.g., Timer2 and
Timer3) with all 16-bit operating modes (except
Asynchronous Counter mode)
• Single 32-bit Timer
• Single 32-bit Synchronous Counter
They also support these features:
•
•
•
•
•
Timer Gate Operation
Selectable Prescaler Settings
Timer Operation during Idle and Sleep modes
Interrupt on a 32-bit Period Register Match
Time Base for Input Capture and Output Compare
Modules (Timer2 and Timer3 only)
• ADC1 Event Trigger (Timer2/3 only)
• ADC2 Event Trigger (Timer4/5 only)
Individually, all eight of the 16-bit timers can function as
synchronous timers or counters. They also offer the
features listed above, except for the event trigger; this
is implemented only with Timer2/3. The operating
modes and enabled features are determined by setting
the appropriate bit(s) in the T2CON, T3CON, T4CON,
T5CON, T6CON, T7CON, T8CON and T9CON registers. T2CON, T4CON, T6CON and T8CON are shown
in generic form in Register 13-1. T3CON, T5CON,
T7CON and T9CON are shown in Register 13-2.
For 32-bit timer/counter operation, Timer2, Timer4,
Timer6 or Timer8 is the least significant word; Timer3,
Timer5, Timer7 or Timer9 is the most significant word
of the 32-bit timers.
Note:
To configure Timer2/3, Timer4/5, Timer6/7 or Timer8/9
for 32-bit operation:
1.
2.
3.
4.
5.
6.
Set the corresponding T32 control bit.
Select the prescaler ratio for Timer2, Timer4,
Timer6 or Timer8 using the TCKPS<1:0> bits.
Set the Clock and Gating modes using the
corresponding TCS and TGATE bits.
Load the timer period value. PR3, PR5, PR7 or
PR9 contains the most significant word of the
value, while PR2, PR4, PR6 or PR8 contains the
least significant word.
If interrupts are required, set the interrupt enable
bit, T3IE, T5IE, T7IE or T9IE. Use the priority
bits, T3IP<2:0>, T5IP<2:0>, T7IP<2:0> or
T9IP<2:0>, to set the interrupt priority. While
Timer2, Timer4, Timer6 or Timer8 control the
timer, the interrupt appears as a Timer3, Timer5,
Timer7 or Timer9 interrupt.
Set the corresponding TON bit.
The timer value at any point is stored in the register
pair, TMR3:TMR2, TMR5:TMR4, TMR7:TMR6 or
TMR9:TMR8. TMR3, TMR5, TMR7 or TMR9 always
contains the most significant word of the count, while
TMR2, TMR4, TMR6 or TMR8 contains the least
significant word.

For 32-bit operation, T3CON, T5CON,
T7CON and T9CON control bits are
ignored. Only T2CON, T4CON, T6CON
and T8CON control bits are used for setup
and control. Timer2, Timer4, Timer6 and
Timer8 clock and gate inputs are utilized
for the 32-bit timer modules, but an interrupt is generated with the Timer3, Timer5,
Ttimer7 and Timer9 interrupt flags.
Clear the T32 bit corresponding to that timer.
Select the timer prescaler ratio using the
TCKPS<1:0> bits.
Set the Clock and Gating modes using the TCS
and TGATE bits.
Load the timer period value into the PRx
register.
If interrupts are required, set the interrupt enable
bit, TxIE. Use the priority bits, TxIP<2:0>, to set
the interrupt priority.
Set the TON bit.

functions are set through T2CON.
When 32-bit timer operation is enabled (T32 = 1) in the Timer Control register (TxCON<3>), the TSIDL bit
must be cleared to operate the 32-bit timer in Idle mode.
The TyCK pin is not available on all timers. Refer to the “Pin Diagrams” section for the available pins.

INPUT CAPTURE
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, 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”, Section 12. “Input Capture”
(DS70248), which is available from the
Microchip website (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 input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The
PIC24HJXXXGPX06A/X08A/X10A
devices
support up to eight input capture channels.
• Capture timer value on every edge (rising and
falling)
• Prescaler Capture Event modes:
- Capture timer value on every 4th rising
edge of input at ICx pin
- Capture timer value on every 16th rising
edge of input at ICx pin
Each input capture channel can select between one of
two 16-bit timers (Timer2 or Timer3) for the time base.
The selected timer can use either an internal or
external clock.
Other operational features include:
• Device wake-up from capture pin during CPU
Sleep and Idle modes
• Interrupt on input capture event
• 4-word FIFO buffer for capture values
- Interrupt optionally generated after 1, 2, 3 or
4 buffer locations are filled
• Input capture can also be used to provide
additional sources of external interrupts.
Note:
The input capture module captures the 16-bit value of
the selected Time Base register when an event occurs
at the ICx pin. The events that cause a capture event
are listed below in three categories:
Only IC1 and IC2 can trigger a DMA data
transfer. If DMA data transfers are
required, the FIFO buffer size must be set
to 1 (ICI<1:0> = 00).
• Simple Capture Event modes:
- Capture timer value on every falling edge of
input at ICx pin
- Capture timer value on every rising edge of
input at ICx pin

OUTPUT COMPARE
The state of the output pin changes when the timer
value matches the Compare register value. The output
compare module generates either a single output
pulse, or a sequence of output pulses, by changing the
state of the output pin on the compare match events.
The output compare module can also generate
interrupts on compare match events.

SERIAL PERIPHERAL
INTERFACE (SPI)
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, 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“, Section 18. “Serial Peripheral
Interface (SPI)” (DS70243), which is
available from the Microchip website
(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 Serial Peripheral Interface (SPI) module is a synchronous serial interface useful for communicating with
other peripheral or microcontroller devices. These
peripheral devices may be serial EEPROMs, shift registers, display drivers, Analog-to-Digital converters, etc.
The SPI module is compatible with SPI and SIOP from
Motorola®.
Note:
In this section, the SPI modules are
referred to together as SPIx, or separately as SPI1 and SPI2. Special Function
Registers will follow a similar notation.
For example, SPIxCON refers to the control register for the SPI1 or SPI2 module.
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 various status conditions.
The serial interface consists of 4 pins: SDIx (serial data
input), SDOx (serial data output), SCKx (shift clock
input or output), and SSx (active-low slave select).
In Master mode operation, SCK is a clock output but in
Slave mode, it is a clock input.

The Inter-Integrated Circuit (I2C) module provides
complete hardware support for both Slave and MultiMaster modes of the I2C serial communication
standard, with a 16-bit interface.
The PIC24HJXXXGPX06A/X08A/X10A devices have
up to two I2C interface modules, denoted as I2C1 and
I2C2. Each I2C module has a 2-pin interface: the SCLx
pin is clock and the SDAx pin is data.
Each I2C module ‘x’ (x = 1 or 2) offers the following key
features:
• I2C interface supporting both master and slave
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 will arbitrate accordingly

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 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 refer to the “dsPIC33F/PIC24H
Family Reference Manual”.
17.2
I2C Registers
I2CxCON and I2CxSTAT are control and status
registers, respectively. The I2CxCON register is
readable and writable. The lower six bits of I2CxSTAT
are read-only. The remaining bits of the I2CSTAT are
read/write.
I2CxRSR is the shift register used for shifting data,
whereas I2CxRCV is the buffer register to which data
bytes are written, or from which data bytes are read.
I2CxRCV is the receive buffer. I2CxTRN is the transmit
register to which bytes are written during a transmit
operation.
The I2CxADD register holds the slave address. A
status bit, ADD10, indicates 10-bit Address mode. The
I2CxBRG acts as the Baud Rate Generator (BRG)
reload value.
In receive operations, I2CxRSR and I2CxRCV together
form a double-buffered receiver. When I2CxRSR
receives a complete byte, it is transferred to I2CxRCV
and an interrupt pulse is generated.

RECEIVER TRANSMITTER
(UART)
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, it is not
intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section
17. “UART” (DS70232) of the
“dsPIC33F/PIC24H Family Reference
Manual”, which is available from the
Microchip website (www.microchip.com).

and bit information.
The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules available in the PIC24HJXXXGPX06A/X08A/X10A device
family. The UART is a full-duplex asynchronous system
that can communicate with peripheral devices, such as
personal computers, LIN, RS-232 and RS-485 interfaces. The module also supports a hardware flow control option with the UxCTS and UxRTS pins and also
includes an IrDA® encoder and decoder.
The primary features of the UART module are:
FIGURE 18-1:
• Full-Duplex, 8 or 9-bit Data Transmission through
the UxTX and UxRX pins
• Even, Odd or No Parity Options (for 8-bit data)
• One or Two Stop bits
• Hardware Flow Control Option with UxCTS and
UxRTS pins
• Fully Integrated Baud Rate Generator 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
• A Separate Interrupt for all UART Error Conditions
• Loopback mode for Diagnostic Support
• Support for Sync and Break Characters
• Supports Automatic Baud Rate Detection
• IrDA® Encoder and Decoder Logic
• 16x Baud Clock Output for IrDA® Support
A simplified block diagram of the UART is shown in
Figure 18-1. The UART module consists of the key
important hardware elements:
• Baud Rate Generator
• Asynchronous Transmitter
• Asynchronous Receiver

Note 1: Both UART1 and UART2 can trigger a DMA data transfer. If U1TX, U1RX, U2TX or U2RX is selected as
a DMA IRQ source, a DMA transfer occurs when the U1TXIF, U1RXIF, U2TXIF or U2RXIF bit gets set as
a result of a UART1 or UART2 transmission or reception.
2: If DMA transfers are required, the UART TX/RX FIFO buffer must be set to a size of 1 byte/word
(i.e., UTXISEL<1:0> = 00 and URXISEL<1:0> = 00).

available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
19.1
Overview
The Enhanced Controller Area Network (ECAN™)
module is a serial interface, useful for communicating
with other CAN modules or microcontroller devices.
This interface/protocol was designed to allow communications
within
noisy
environments.
The
PIC24HJXXXGPX06A/X08A/X10A devices contain up
to two ECAN modules.
The CAN module is a communication controller implementing the CAN 2.0 A/B protocol, as defined in the
BOSCH specification. The module will support CAN 1.2,
CAN 2.0A, CAN 2.0B Passive and CAN 2.0B Active
versions of the protocol. The module implementation is
a full CAN system. The CAN specification is not covered
within this data sheet. The reader may refer to the
BOSCH CAN specification for further details.
The module features are as follows:
• Implementation of the CAN protocol, CAN 1.2,
CAN 2.0A and CAN 2.0B
• Standard and extended data frames
• 0-8 bytes data length
• Programmable bit rate up to 1 Mbit/sec
• Automatic response to remote transmission
requests
• Up to 8 transmit buffers with application specified
prioritization and abort capability (each buffer may
contain up to 8 bytes of data)
• Up to 32 receive buffers (each buffer may contain
up to 8 bytes of data)
• Up to 16 full (standard/extended identifier)
acceptance filters
• 3 full acceptance filter masks
• DeviceNet™ addressing support
• Programmable wake-up functionality with
integrated low-pass filter
• Programmable Loopback mode supports self-test
operation

• Signaling via interrupt capabilities for all CAN
receiver and transmitter error states
• Programmable clock source
• Programmable link to input capture module (IC2
for both CAN1 and CAN2) for time-stamping and
network synchronization
• Low-power Sleep and Idle mode
The CAN bus module consists of a protocol engine and
message buffering/control. The CAN protocol engine
handles all functions for receiving and transmitting
messages on the CAN bus. Messages are transmitted
by first loading the appropriate data registers. Status
and errors can be checked by reading the appropriate
registers. Any message detected on the CAN bus is
checked for errors and then matched against filters to
see if it should be received and stored in one of the
receive registers.
19.2
Frame Types
The CAN module transmits various types of frames
which include data messages, remote transmission
requests and as other frames that are automatically
generated for control purposes. The following frame
types are supported:
• Standard Data Frame:
A standard data frame is generated by a node when
the node wishes to transmit data. It includes an 11-bit
standard identifier (SID) but not an 18-bit extended
identifier (EID).
• Extended Data Frame:
An extended data frame is similar to a standard data
frame but includes an extended identifier as well.
• Remote Frame:
It is possible for a destination node to request the
data from the source. For this purpose, the
destination node sends a remote frame with an identifier that matches the identifier of the required data
frame. The appropriate data source node will then
send a data frame as a response to this remote
request.
• Error Frame:
An error frame is generated by any node that detects
a bus error. An error frame consists of two fields: an
error flag field and an error delimiter field.
• Overload Frame:
An overload frame can be generated by a node as a
result of two conditions. First, the node detects a
dominant bit during interframe space which is an illegal condition. Second, due to internal conditions, the
node is not yet able to start reception of the next
message. A node may generate a maximum of 2
sequential overload frames to delay the start of the
next message.
• Interframe Space:
Interframe space separates a proceeding frame (of
whatever type) from a following data or remote
frame.

19.3
Modes of Operation
The CAN module can operate in one of several operation
modes selected by the user. These modes include:
•
•
•
•
•
•
Initialization Mode
Disable Mode
Normal Operation Mode
Listen Only Mode
Listen All Messages Mode
Loopback Mode
Modes are requested by setting the REQOP<2:0> bits
(CiCTRL1<10:8>). Entry into a mode is Acknowledged
by
monitoring
the
OPMODE<2:0>
bits
(CiCTRL1<7:5>). The module will not change the mode
and the OPMODE bits until a change in mode is
acceptable, generally during bus Idle time, which is
defined as at least 11 consecutive recessive bits.
19.3.1
INITIALIZATION MODE
In the Initialization mode, the module will not transmit or
receive. The error counters are cleared and the interrupt flags remain unchanged. The programmer will
have access to Configuration registers that are access
restricted in other modes. The module will protect the
user from accidentally violating the CAN protocol
through programming errors. All registers which control
the configuration of the module can not be modified
while the module is on-line. The CAN module will not
be allowed to enter the Configuration mode while a
transmission is taking place. The Configuration mode
serves as a lock to protect the following registers.
•
•
•
•
•
All Module Control Registers
Baud Rate and Interrupt Configuration Registers
Bus Timing Registers
Identifier Acceptance Filter Registers
Identifier Acceptance Mask Registers
19.3.2
DISABLE MODE
In Disable mode, the module will not transmit or
receive. The module has the ability to set the WAKIF bit
due to bus activity, however, any pending interrupts will
remain and the error counters will retain their value.
If the REQOP<2:0> bits (CiCTRL1<10:8>) = 001, the
module will enter the Module Disable mode. If the module
is active, the module will wait for 11 recessive bits on the
CAN bus, detect that condition as an Idle bus, then
accept the module disable command. When the
OPMODE<2:0> bits (CiCTRL1<7:5>) = 001, that indicates whether the module successfully went into Module
Disable mode. The I/O pins will revert to normal I/O
function when the module is in the Module Disable mode.
© 2011 Microchip Technology Inc.
The module can be programmed to apply a low-pass
filter function to the CiRX input line while the module or
the CPU is in Sleep mode. The WAKFIL bit
(CiCFG2<14>) enables or disables the filter.
Note:
19.3.3
Typically, if the CAN module is allowed to
transmit in a particular mode of operation
and a transmission is requested
immediately after the CAN module has
been placed in that mode of operation, the
module waits for 11 consecutive recessive
bits on the bus before starting
transmission. If the user application
switches to Disable mode within this 11-bit
period, the transmission is then aborted
and the corresponding TXABT bit is set
and the TXREQ bit is cleared.
NORMAL OPERATION MODE
Normal Operation mode is selected when
REQOP<2:0> = 000. In this mode, the module is
activated and the I/O pins will assume the CAN bus
functions. The module will transmit and receive CAN
bus messages via the CiTX and CiRX pins.
19.3.4
LISTEN ONLY MODE
If the Listen Only mode is activated, the module on the
CAN bus is passive. The transmitter buffers revert to
the port I/O function. The receive pins remain inputs.
For the receiver, no error flags or Acknowledge signals
are sent. The error counters are deactivated in this
state. The Listen Only mode can be used for detecting
the baud rate on the CAN bus. To use this, it is necessary that there are at least two further nodes that
communicate with each other.
19.3.5
LISTEN ALL MESSAGES MODE
The module can be set to ignore all errors and receive
any message. The Listen All Messages mode is activated by setting REQOP<2:0> = ‘111’. In this mode,
the data which is in the message assembly buffer, until
the time an error occurred, is copied in the receive buffer and can be read via the CPU interface.
19.3.6
LOOPBACK MODE
If the Loopback mode is activated, the module will connect the internal transmit signal to the internal receive
signal at the module boundary. The transmit and
receive pins revert to their port I/O function.

10-BIT/12-BIT
ANALOG-TO-DIGITAL
CONVERTER (ADC)
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
family of devices. However, 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”, Section 16. “Analog-to-Digital
Converter (ADC)” (DS70225), which is
available from the Microchip website
(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.
Depending on the particular device pinout, the Analog-to-Digital Converter can have up to 32 analog input
pins, designated AN0 through AN31. In addition, there
are two analog input pins for external voltage reference
connections. These voltage reference inputs may be
shared with other analog input pins. The actual number
of analog input pins and external voltage reference
input configuration will depend on the specific device.
Refer to the device data sheet for further details.
A block diagram of the Analog-to-Digital Converter is
shown in Figure 20-1.
20.2
1.
The PIC24HJXXXGPX06A/X08A/X10A devices have
up to 32 Analog-to-Digital input channels. These
devices also have up to 2 Analog-to-Digital converter
modules (ADCx, where ‘x’ = 1 or 2), each with its own
set of Special Function Registers.
The AD12B bit (ADxCON1<10>) allows each of the
ADC modules to be configured by the user as either a
10-bit, 4-sample/hold ADC (default configuration) or a
12-bit, 1-sample/hold ADC.
Note:
20.1
The ADC module needs to be disabled
before modifying the AD12B bit.
Key Features
The 10-bit ADC configuration has the following key
features:
•
•
•
•
•
•
•
•
•
•
Successive Approximation (SAR) conversion
Conversion speeds of up to 1.1 Msps
Up to 32 analog input pins
External voltage reference input pins
Simultaneous sampling of up to four analog input
pins
Automatic Channel Scan mode
Selectable conversion trigger source
Selectable Buffer Fill modes
Two result alignment options (signed/unsigned)
Operation during CPU Sleep and Idle modes
The 12-bit ADC configuration supports all the above
features, except:
• In the 12-bit configuration, conversion speeds of
up to 500 ksps are supported
• There is only 1 sample/hold amplifier in the 12-bit
configuration, so simultaneous sampling of
multiple channels is not supported.
© 2011 Microchip Technology Inc.
Analog-to-Digital Initialization
The following configuration steps should be performed.
2.
Configure the ADC module:
a) Select port pins as analog inputs
(ADxPCFGH<15:0> or ADxPCFGL<15:0>)
b) Select voltage reference source to match
expected range on analog inputs
(ADxCON2<15:13>)
c) Select the analog conversion clock to
match desired data rate with processor
clock (ADxCON3<7:0>)
d) Determine how many S/H channels will
be
used
(ADxCON2<9:8>
and
ADxPCFGH<15:0> or ADxPCFGL<15:0>)
e) Select the appropriate sample/conversion
sequence
(ADxCON1<7:5>
and
ADxCON3<12:8>)
f) Select how conversion results are
presented in the buffer (ADxCON1<9:8>)
g) Turn on the ADC module (ADxCON1<15>)
Configure ADC interrupt (if required):
a) Clear the ADxIF bit
b) Select ADC interrupt priority
20.3
ADC and DMA
If more than one conversion result needs to be buffered
before triggering an interrupt, DMA data transfers can
be used. Both ADC1 and ADC2 can trigger a DMA data
transfer. If ADC1 or ADC2 is selected as the DMA IRQ
source, a DMA transfer occurs when the AD1IF or
AD2IF bit gets set as a result of an ADC1 or ADC2
sample conversion sequence.
The SMPI<3:0> bits (ADxCON2<5:2>) are used to
select how often the DMA RAM buffer pointer is
incremented.
The ADDMABM bit (ADxCON1<12>) determines how
the conversion results are filled in the DMA RAM buffer
area being used for ADC. If this bit is set, DMA buffers
are written in the order of conversion. The module will
provide an address to the DMA channel that is the
same as the address used for the non-DMA
stand-alone buffer. If the ADDMABM bit is cleared, the
DMA buffers are written in Scatter/Gather mode. The
module will provide a scatter/gather address to the
DMA channel, based on the index of the analog input
and the size of the DMA buffer.

SPECIAL FEATURES
21.1
Configuration Bits
PIC24HJXXXGPX06A/X08A/X10A devices provide
nonvolatile memory implementation for device
configuration bits. Refer to Section 25. “Device Configuration” (DS70194) of the “dsPIC33F/PIC24H
Family Reference Manual”, for more information on this
implementation.
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
families of devices. However, it is not
intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section
23.
“CodeGuard™
Security”
(DS70239), Section 24. “Programming
and Diagnostics” (DS70246), and Section 25. “Device Configuration”
(DS70231) in the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com).
The Configuration bits can be programmed (read as
‘0’), or left unprogrammed (read as ‘1’), to select various device configurations. These bits are mapped
starting at program memory location 0xF80000.
The device Configuration register map is shown in
Table 21-1.
The individual Configuration bit descriptions for the
Configuration registers are shown in Table 21-2.
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.
Note that address 0xF80000 is beyond the user program
memory space. In fact, it belongs to the configuration
memory space (0x800000-0xFFFFFF), which can only
be accessed using table reads and table writes.
PIC24HJXXXGPX06A/X08A/X10A devices include
several features intended to maximize application flexibility and reliability, and minimize cost through elimination of external components. These are:
•
•
•
•
•
Flexible Configuration
Watchdog Timer (WDT)
Code Protection and CodeGuard™ Security
JTAG Boundary Scan Interface
In-Circuit Serial Programming™ (ICSP™)
programming capability
• In-Circuit Emulation

operate at a higher typical voltage, such as 3.3V. To
simplify system design, all devices in the
PIC24HJXXXGPX06A/X08A/X10A family 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. The regulator requires that a low-ESR (less
than 5 ohms) capacitor (such as tantalum or ceramic)
be connected to the VCAP pin (Figure 21-1). This helps
to maintain the stability of the regulator. The
recommended value for the filter capacitor is provided
in Table 24-13 of Section 24.1 “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 μs 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.

Brown-out Reset (BOR)
The BOR (Brown-out Reset) module is based on an
internal voltage reference circuit that monitors the regulated voltage VCAP. 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 (i.e.,
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 will generate a Reset pulse which will reset the
device. The BOR will select the clock source, based on
the device Configuration bit values (FNOSC<2:0> and
POSCMD<1:0>). Furthermore, if an oscillator mode is
selected, the BOR will activate the Oscillator Start-up
Timer (OST). The system clock is held until OST
expires. If the PLL is used, the clock will be held until
the LOCK bit (OSCCON<5>) is ‘1’.
Concurrently, the PWRT time-out (TPWRT) will be
applied before the internal Reset is released. If
TPWRT = 0 and a crystal oscillator is being used, a
nominal delay of TFSCM = 100 is applied. The total
delay in this case is TFSCM.
The BOR Status bit (RCON<1>) will be set to indicate
that a BOR has occurred. The BOR circuit continues to
operate while in Sleep or Idle modes and will reset the
device should VDD fall below the BOR threshold
voltage.

Watchdog Timer (WDT)
For PIC24HJXXXGPX06A/X08A/X10A devices, the
WDT is driven by the LPRC oscillator. When the WDT
is enabled, the clock source is also enabled.
The nominal WDT clock source from LPRC is 32 kHz.
This feeds a prescaler than can be configured for either
5-bit (divide-by-32) or 7-bit (divide-by-128) operation.
The prescaler is set by the WDTPRE Configuration bit.
With a 32 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 a total 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 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
FIGURE 21-2:
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 or IDLE bits
(RCON<3,2>) will need to be cleared in software after
the device wakes up.
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.
Note:
The CLRWDT and PWRSAV instructions
clear the prescaler and postscaler counts
when executed.
The WDT is enabled or disabled by the FWDTEN
Configuration bit in the FWDT Configuration register.
When the FWDTEN Configuration bit is set, the WDT is
always enabled.
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 to enable the WDT for critical code segments and disable the WDT during
non-critical segments for maximum power savings.
Note:
If the WINDIS bit (FWDT<6>) is cleared,
the CLRWDT instruction should be executed
by the application software only during the
last 1/4 of the WDT period. This CLRWDT
window can be determined by using a timer.
If a CLRWDT instruction is executed before
this window, a WDT Reset occurs.

JTAG Interface
PIC24HJXXXGPX06A/X08A/X10A devices implement
a JTAG interface, which supports boundary scan
device testing, as well as in-circuit programming.
Detailed information on the interface will be provided in
future revisions of the document.
Note:
21.6
For further information, refer to the
dsPIC33F/PIC24H Family Reference
Manual“, Section 24. “Programming

available from the Microchip website
(www.microchip.com).
Code Protection and
CodeGuard™ Security
The PIC24H product families offer advanced implementation of CodeGuard™ Security. CodeGuard
Security enables multiple parties to securely share
resources (memory, interrupts and peripherals) on a
single chip. This feature helps protect individual
Intellectual Property in collaborative system designs.
When coupled with software encryption libraries,
CodeGuard Security can be used to securely update
Flash even when multiple IP are resident on the single
chip. The code protection features vary depending on
the actual PIC24H implemented. The following
sections provide an overview these features.
The code protection features are controlled by the
Configuration registers: FBS, FSS and FGS.
Note:
For further information, refer to the
“dsPIC33F/PIC24H Family Reference
Manual”, Section 23. “CodeGuard™
Security” (DS70239), which is available

In-Circuit Serial Programming
Programming Capability
PIC24HJXXXGPX06A/X08A/X10A family digital signal
controllers can be serially programmed while in the end
application circuit. This is simply done with two lines for
clock and data and three other lines for power, ground
and the programming sequence. 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. Please refer to the “dsPIC33F/PIC24H
Flash
Programming
Specification”
(DS70152)
document for details about ICSP programming
capability.
Any one out of three pairs of programming clock/data
pins may be used:
• PGEC1 and PGED1
• PGEC2 and PGED2
• PGEC3 and PGED3
21.8
In-Circuit Debugger
When MPLAB® ICD 2 is selected as a debugger, the
in-circuit debugging functionality is enabled. This function allows simple debugging functions when used with
MPLAB IDE. Debugging functionality is controlled
through the PGECx (Emulation/Debug Clock) and
PGEDx (Emulation/Debug Data) pin functions.
Any one out of three pairs of debugging clock/data pins
may be used:
• PGEC1 and PGED1
• PGEC2 and PGED2
• PGEC3 and PGED3
To use the in-circuit debugger function of the device,
the design must implement ICSP programming capability connections to MCLR, VDD, VSS and the PGEDx/
PGECx pin pair. In addition, when the feature is
enabled, some of the resources are not available for
general use. These resources include the first 80 bytes
of data RAM and two I/O pins.

INSTRUCTION SET SUMMARY
This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
families of devices. However, it is not
intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
related section in the “dsPIC33F/PIC24H
Family Reference Manual”, which is
available from the Microchip website
(www.microchip.com).
The PIC24H instruction set is identical to that of the
PIC24F, and is a subset of the dsPIC30F/33F
instruction set.
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 22-1 shows the general symbols used in
describing the instructions.
The PIC24H instruction set summary in Table 22-2 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:
• The file register specified by the value ‘f’
• The destination, which could either be the file
register ‘f’ or the W0 register, which is denoted as
‘WREG’
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 may
use some of the following operands:
• A literal value to be loaded into a W register or file
register (specified by the value of ‘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 control instructions may use some of the following
operands:
• A program memory address
• The mode of the table read and table write
instructions
All instructions are a single word, except for certain
double word instructions, which were made double
word instructions so that all the required information is
available 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.
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 (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 double word
instruction. Moreover, double word moves require two
cycles. The double word instructions execute in two
instruction cycles.

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

a comprehensive stimulus controller. Registers can be
logged to files for further run-time analysis. The trace
buffer and logic analyzer display extend the power of
the simulator to record and track program execution,
actions on I/O, most peripherals and internal registers.
The MPLAB SIM Software Simulator fully supports
symbolic debugging using the MPLAB C Compilers,
and the MPASM and MPLAB Assemblers. The software simulator offers the flexibility to develop and
debug code outside of the hardware laboratory environment, making it an excellent, economical software
development tool.

ELECTRICAL CHARACTERISTICS
This section provides an overview of PIC24HJXXXGPX06A/X08A/X10A electrical characteristics. Additional
information is provided in future revisions of this document as it becomes available.
Absolute maximum ratings for the PIC24HJXXXGPX06A/X08A/X10A family are listed below. Exposure to these maximum rating conditions for extended periods can affect device reliability. Functional operation of the device at these or
any other conditions above the parameters indicated in the operation listings of this specification is not implied.
Absolute Maximum Ratings(1)
Ambient temperature under bias.............................................................................................................-40°C to +125°C
Storage temperature .............................................................................................................................. -65°C to +160°C
Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +4.0V
Voltage on any pin that is not 5V tolerant with respect to VSS(4) .................................................... -0.3V to (VDD + 0.3V)
Voltage on any 5V tolerant pin with respect to VSS when VDD ≥ 3.0V(4) .................................................. -0.3V to +5.6V
Voltage on any 5V tolerant pin with respect to VSS when VDD < 3.0V(4) ..................................................... -0.3V to 3.6V
Voltage on VCAP with respect to VSS ...................................................................................................... 2.25V to 2.75V
Maximum current out of VSS pin ...........................................................................................................................300 mA
Maximum current into VDD pin(2) ...........................................................................................................................250 mA
Maximum output current sunk by any I/O pin(3) ........................................................................................................4 mA
Maximum output current sourced by any I/O pin(3) ...................................................................................................4 mA
Maximum current sunk by all ports .......................................................................................................................200 mA
Maximum current sourced by all ports(2) ...............................................................................................................200 mA
Note 1: Stresses above those listed under “Absolute Maximum Ratings” can cause permanent damage to the
device. This is a stress rating only, and functional operation of the device at those or any other conditions
above those indicated in the operation listings of this specification is not implied. Exposure to maximum
rating conditions for extended periods can affect device reliability.
2: Maximum allowable current is a function of device maximum power dissipation (see Table 24-2).
3: Exceptions are CLKOUT, which is able to sink/source 25 mA, and the VREF+, VREF-, SCLx, SDAx, PGECx
and PGEDx pins, which are able to sink/source 12 mA.
4: See the “Pin Diagrams” section for 5V tolerant pins.

Data in “Typical” column is at 3.3V, 25°C unless otherwise stated.
The supply current is mainly 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: OSC1
driven with external square wave from rail to rail. 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 (PMD bits
are all zeroed).

Data in “Typ” column is at 3.3V, 25°C unless otherwise stated.
The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified
levels represent normal operating conditions. Higher leakage current may be measured at different input
voltages.
Negative current is defined as current sourced by the pin.
See “Pin Diagrams” for a list of 5V tolerant pins.
VIL source < (VSS – 0.3). Characterized but not tested.
Non-5V tolerant pins VIH source > (VDD + 0.3), 5V tolerant pins VIH source > 5.5V. Characterized but not

Digital 5V tolerant pins cannot tolerate any “positive” input injection current from input sources > 5.5V.
Injection currents > | 0 | can affect the ADC results by approximately 4-6 counts.
Any number and/or combination of I/O pins not excluded under IICL or IICH conditions are permitted provided the mathematical “absolute instantaneous” sum of the input injection currents from all pins do not
exceed the specified limit. Characterized but not tested.

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.

Data in “Typ” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only
and are not tested.
These parameters are characterized by similarity but are not tested in manufacturing. This specification is
based on clock cycle by clock cycle measurements. To calculate the effective jitter for individual time base
or communication clocks used by peripherals use the formula:
2:
Peripheral Clock Jitter = DCLK / √(FOSC/Peripheral bit rate clock)
Example Only: Fosc = 80 MHz, DCLK = 3%, SPI bit rate clock, (i.e. SCK), is 5 MHz
SPI SCK Jitter = [ DCLK / √(80 MHz/5 MHz)] = [3%/ √16] = [3% / 4] = 0.75%

HIGH TEMPERATURE ELECTRICAL CHARACTERISTICS
This section provides an overview of PIC24HJXXXGPX06A/X08A/X10A electrical characteristics for devices operating
in an ambient temperature range of -40°C to +150°C.
Note:
Programming of the Flash memory is not allowed above 125°C.
The specifications between -40°C to +150°C are identical to those shown in Section 24.0 “Electrical Characteristics”
for operation between -40°C to +125°C, with the exception of the parameters listed in this section.
Parameters in this section begin with an H, which denotes High temperature. For example, parameter DC10 in
Section 24.0 “Electrical Characteristics” is the Industrial and Extended temperature equivalent of HDC10.
Absolute maximum ratings for the PIC24HJXXXGPX06A/X08A/X10A high temperature devices are listed below.
Exposure to these maximum rating conditions for extended periods can affect device reliability. Functional operation of
the device at these or any other conditions above the parameters indicated in the operation listings of this specification
is not implied.
Absolute Maximum Ratings(1)
Ambient temperature under bias(4) .........................................................................................................-40°C to +150°C
Storage temperature .............................................................................................................................. -65°C to +160°C
Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +4.0V
Voltage on any pin that is not 5V tolerant with respect to VSS(5) .................................................... -0.3V to (VDD + 0.3V)
Voltage on any 5V tolerant pin with respect to VSS when VDD < 3.0V(5) ....................................... -0.3V to (VDD + 0.3V)
Voltage on any 5V tolerant pin with respect to VSS when VDD ≥ 3.0V(5) .................................................... -0.3V to 5.6V
Voltage on VCAP with respect to VSS ...................................................................................................... 2.25V to 2.75V
Maximum current out of VSS pin .............................................................................................................................60 mA
Maximum current into VDD pin(2) .............................................................................................................................60 mA
Maximum junction temperature............................................................................................................................. +155°C
Maximum output current sunk by any I/O pin(3) ........................................................................................................1 mA
Maximum output current sourced by any I/O pin(3) ...................................................................................................1 mA
Maximum current sunk by all ports combined ........................................................................................................10 mA
Maximum current sourced by all ports combined(2) ................................................................................................10 mA
Note 1: Stresses above those listed under “Absolute Maximum Ratings” can cause permanent damage to the
device. This is a stress rating only, and functional operation of the device at those or any other conditions
above those indicated in the operation listings of this specification is not implied. Exposure to maximum
rating conditions for extended periods can affect device reliability.
2: Maximum allowable current is a function of device maximum power dissipation (see Table 25-2).
3: Unlike devices at 125°C and below, the specifications in this section also apply to the CLKOUT, VREF+,

Base IPD is measured with all peripherals and clocks shut down. All I/Os are configured as inputs and
pulled to VSS. WDT, etc., are all switched off, and VREGS (RCON<8>) = 1.
The Δ current is the additional current consumed when the 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.
These parameters are characterized, but are not tested in manufacturing.

APPENDIX A:
MIGRATING FROM
PIC24HJXXXGPX06/
X08/X10 DEVICES TO
PIC24HJXXXGPX06A/
X08A/X10A DEVICES
PIC24HJXXXGPX06A/X08A/X10A
devices
were
designed to enhance the PIC24HJXXXGPX06/X08/
X10 families of devices.
In general, the PIC24HJXXXGPX06A/X08A/X10A
devices
are
backward-compatible
with
PIC24HJXXXGPX06/X08/X10 devices; however, manufacturing
differences
may
cause
PIC24HJXXXGPX06A/X08A/X10A devices to behave
differently from PIC24HJXXXGPX06/X08/X10 devices.
Therefore, complete system test and characterization
is recommended if PIC24HJXXXGPX06A/X08A/X10A
devices are used to replace PIC24HJXXXGPX06/X08/
X10 devices.
The following enhancements were introduced:
• Extended temperature support of up to +125ºC
• Enhanced Flash module with higher endurance
and retention
• New PLL Lock Enable configuration bit
• Added Timer5 trigger for ADC1 and Timer3
trigger for ADC2
