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.

The PIC24HJXXXGPX06/X08/X10 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).
© 2007 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 PIC24HJXXXGPX06/X08/X10 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
PIC24HJXXXGPX06/X08/X10 Central Processing Unit
(CPU) with extensive mathematical processing
capability. Flexible and deterministic interrupt handling,
coupled with a powerful array of peripherals, renders
the PIC24HJXXXGPX06/X08/X10 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
PIC24HJXXXGPX06/X08/X10 devices.
Figure 1-1 shows a general block diagram of the
various core and peripheral modules in the
PIC24HJXXXGPX06/X08/X10 family of devices, while
Table 1-1 lists the functions of the various pins shown
in the pinout diagrams.

CPU
This data sheet summarizes the features
of
this
group
of PIC24HJXXXGPX06/X08/X10 devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
“PIC24H Family Reference Manual”.
Refer to the Microchip web site
(www.microchip.com) for the latest
PIC24H Family Reference Manual
sections.
The PIC24HJXXXGPX06/X08/X10 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.
The PIC24HJXXXGPX06/X08/X10 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.
2.1
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.
2.2
Special MCU Features
The PIC24HJXXXGPX06/X08/X10 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 PIC24HJXXXGPX06/X08/X10 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 PIC24HJXXXGPX06/X08/X10 instruction set
includes many addressing modes and is designed for
optimum C compiler efficiency. For most instructions,
the PIC24HJXXXGPX06/X08/X10 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.
A block diagram of the CPU is shown in Figure 2-1,
and
the
programmer’s
model
for
the
PIC24HJXXXGPX06/X08/X10 is shown in Figure 2-2.

PIC24HJXXXGPX06/X08/X10
2.4
Arithmetic Logic Unit (ALU)
The PIC24HJXXXGPX06/X08/X10 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.
2.4.3
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.
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 “dsPIC30F/33F Programmer’s Reference
Manual” (DS70157) for information on the SR bits
affected by each instruction.
The PIC24HJXXXGPX06/X08/X10 CPU incorporates
hardware support for both multiplication and division.
This includes a dedicated hardware multiplier and support hardware for 16-bit divisor division.
2.4.1
MULTIPLIER
Using the high-speed 17-bit x 17-bit multiplier, the ALU
supports unsigned, signed or mixed-sign operation in
several multiplication modes:
1.
2.
3.
4.
5.
6.
7.
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
2.4.2
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:
1.
2.
3.
4.
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.

The PIC24HJXXXGPX06/X08/X10 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.

3.1
Program Address Space
The program address memory space of the
PIC24HJXXXGPX06/X08/X10 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 3.4 “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 PIC24HJXXXGPX06/X08/X10
family of devices are shown in Figure 3-1.

PROGRAM MEMORY
ORGANIZATION
3.1.2
All PIC24HJXXXGPX06/X08/X10 devices reserve the
addresses between 0x00000 and 0x000200 for hardcoded 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 3-2).
PIC24HJXXXGPX06/X08/X10 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 6.1 “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.

3.2
Data Address Space
The PIC24HJXXXGPX06/X08/X10 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 3-3 and Figure 3-4.
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 3.4.3 “Reading Data From
Program Memory Using Program Space Visibility”).
PIC24HJXXXGPX06/X08/X10 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.
3.2.1
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.
3.2.2
DATA MEMORY ORGANIZATION
AND ALIGNMENT
To maintain backward compatibility with PICmicro®
MCU devices and improve data space memory usage
efficiency, the PIC24HJXXXGPX06/X08/X10 instruction set supports both word and byte operations. As a
consequence of byte accessibility, all effective address
calculations are internally scaled to step through wordaligned 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.
DS70175F-page 26
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.
3.2.3
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
PIC24HJXXXGPX06/X08/X10 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 3-1
through Table 3-31.
Note:
3.2.4
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 PIC24HJXXXGPX06/X08/X10 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 transferred from
0xFFFE
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:
DS70175F-page 28
DMA RAM can be used for general
purpose data storage if the DMA function
is not required in an application.

3.2.6
SOFTWARE STACK
3.2.7
In addition to its use as a working register, the W15
register in the PIC24HJXXXGPX06/X08/X10 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 pre-decrements for stack pops and post-increments for stack
pushes, as shown in Figure 3-5. 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.

DATA RAM PROTECTION FEATURE
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 3-1 for an overview of the BSRAM and SSRAM
SFRs.
3.3
Instruction Addressing Modes
The addressing modes in Table 3-32 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.
3.3.1
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.
3.3.2
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:
•
•
•
•
•
Register Direct
Register Indirect
Register Indirect Post-Modified
Register Indirect Pre-Modified
5-bit or 10-bit Literal
Note:
Not all instructions support all the
addressing modes given above. Individual
instructions may support different subsets
of these addressing modes.
DS70175F-page 47
PIC24HJXXXGPX06/X08/X10
TABLE 3-32:
FUNDAMENTAL ADDRESSING MODES SUPPORTED
Addressing Mode
Description
File Register Direct
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
3.3.3
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:
3.3.4
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.
DS70175F-page 48
3.4
Interfacing Program and Data
Memory Spaces
The PIC24HJXXXGPX06/X08/X10 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
PIC24HJXXXGPX06/X08/X10 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.
3.4.1
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).
© 2007 Microchip Technology Inc.
PIC24HJXXXGPX06/X08/X10
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 3-33:
Table 3-33 and Figure 3-6 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 4.0 “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, 8000h and higher,
maps directly into a corresponding program memory
address (see Figure 3-8), only the lower 16 bits of the
FIGURE 3-8:
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.

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.
4.1
The PIC24HJXXXGPX06/X08/X10 devices contain
internal Flash program memory for storing and executing application code. The memory is readable, writable
and erasable during normal operation over the entire
VDD range.
Flash memory can be programmed in two ways:
1.
2.
In-Circuit Serial Programming™ (ICSP™)
programming capability
Run-Time Self-Programming (RTSP)
ICSP
programming
capability
allows
a
PIC24HJXXXGPX06/X08/X10 device to be serially
programmed while in the end application circuit. This is
simply done with two lines for programming clock and
programming data (one of the alternate programming
pin pairs: PGC1/PGD1, PGC2/PGD2 or PGC3/PGD3,
and three other lines for power (VDD), ground (VSS) and
Master Clear (MCLR). This allows customers to manufacture boards with unprogrammed devices and then
program the digital signal controller just before shipping
FIGURE 4-1:
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 4-1.
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 PIC24HJXXXGPX06/X08/X10 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 23-12: “DC Characteristics: Program
Memory” 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.
4.3
Control Registers
There are two SFRs used to read and write the
program Flash memory: NVMCON and NVMKEY.
The NVMCON register (Register 4-1) 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 55h and AAh to the
NVMKEY register. Refer to Section 4.4 “Programming
Operations” for further details.
4.4
Programming Operations
A complete programming sequence is necessary for
programming or erasing the internal Flash in RTSP
mode. A programming operation is nominally 4 ms in
duration and the processor stalls (waits) until the operation is finished. Setting the WR bit (NVMCON<15>)
starts the operation, and the WR bit is automatically
cleared when the operation is finished.
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.

4.4.1
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 4-1):
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 4-1:
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 4-3.

6.
Write the first 64 instructions from data RAM into
the program memory buffers (see Example 4-2).
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.

A program memory page erase operation
is set up by performing a dummy table

within the page. This methodology is different from the page erase operation on
dsPIC30F/33F devices in which the erase
page was selected using a dedicated pair
of registers (NVMADRU and NVMADR).

BOR: Brown-out Reset
MCLR: Master Clear Pin Reset

WDT: Watchdog Timer Reset
TRAPR: Trap Conflict Reset
IOPUWR: Illegal Opcode and Uninitialized W
Register Reset
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 5-1). 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.
A simplified block diagram of the Reset module is
shown in Figure 5-1.
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.

Clock Source Selection at Reset
If clock switching is enabled, the system clock source at
device Reset is chosen, as shown in Table 5-2. 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 5-3. 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.
5.2.2
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.
DS70175F-page 64
5.2.2.1
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.
5.3
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.

Note:
INTERRUPT CONTROLLER
This data sheet summarizes the features
of this group of PIC24HJXXXGPX06/X08/
X10 devices. It is not intended to be a
comprehensive reference source. To complement the information in this data sheet,
refer to the “PIC24H Family Reference
Manual”. Refer to the Microchip web site
(www.microchip.com) for the latest
PIC24H Family Reference Manual
sections.
The PIC24HJXXXGPX06/X08/X10 interrupt controller
reduces the numerous peripheral interrupt request
signals to a single interrupt request signal to the
PIC24HJXXXGPX06/X08/X10 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
6.1
Interrupt Vector Table
The Interrupt Vector Table (IVT) is shown in Figure 6-1.
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).
6.1.1
ALTERNATE VECTOR TABLE
The Alternate Interrupt Vector Table (AIVT) is located
after the IVT, as shown in Figure 6-1. 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.
6.2
Reset Sequence
A device Reset is not a true exception because the
interrupt controller is not involved in the Reset process.
The PIC24HJXXXGPX06/X08/X10 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 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.
PIC24HJXXXGPX06/X08/X10 devices implement up
to 61 unique interrupts and 5 nonmaskable traps.
These are summarized in Table 6-1 and Table 6-2.

PIC24HJXXXGPX06/X08/X10
6.3
Interrupt Control and Status
Registers
PIC24HJXXXGPX06/X08/X10 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 6-1. 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 6-1,
SR: CPU STATUS Register(1) through Register 6-32,
IPC17: Interrupt Priority Control Register 17, in the
following pages.

Interrupt Setup Procedures
6.4.1
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.
6.4.2
6.4.3
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.
6.4.4
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)
This data sheet summarizes the features
of
this
group
of PIC24HJXXXGPX06/X08/X10 devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
“PIC24H Family Reference Manual”.
Refer to the Microchip web site
(www.microchip.com) for the latest
PIC24H Family Reference Manual
sections.
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 PIC24HJXXXGPX06/X08/X10 peripherals that
can utilize DMA are listed in Table 7-1 along with their
associated Interrupt Request (IRQ) numbers.
TABLE 7-1:
PERIPHERALS WITH DMA
SUPPORT
Peripheral
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.

CONFIGURATION
Note:
• An on-chip PLL to scale the internal operating
frequency to the required system clock frequency
• The internal FRC oscillator can also be used with
the PLL, thereby allowing full-speed operation
without any external clock generation hardware
• Clock switching between various clock sources
• Programmable clock postscaler for system power
savings
• A Fail-Safe Clock Monitor (FSCM) that detects
clock failure and takes fail-safe measures
• A Clock Control register (OSCCON)
• Nonvolatile Configuration bits for main oscillator
selection.

8.1.1
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.
The primary oscillator can use one of the following as
its clock source:
1.
2.
3.
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 in the
range of 0.8 MHz to 64 MHz. The 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 8.1.3 “PLL
Configuration”.
8.1.2
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 20.1 “Configuration Bits” for further details.)
The Initial Oscillator Selection Configuration bits,
FNOSC<2:0> (FOSCSEL<2:0>), and the Primary Oscillator Mode Select Configuration bits, POSCMD<1:0>
DS70175F-page 120
(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 8-1.
The output of the oscillator (or the output of the PLL if
a PLL mode has been selected) FOSC is divided by 2 to
generate the device instruction clock (FCY). FCY
defines the operating speed of the device, and speeds
up to
40
MHz
are
supported by
the
PIC24HJXXXGPX06/X08/X10 architecture.
Instruction execution speed or device operating
frequency, FCY, is given by:
EQUATION 8-1:
DEVICE OPERATING
FREQUENCY
FCY = FOSC/2
8.1.3
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 8-2.
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:

PIC24HJXXXGPX06/X08/X10
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.

PIC24HJXXXGPX06/X08/X10
8.2
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,
PIC24HJXXXGPX06/X08/X10 devices have a safeguard lock built into the switch process.
Note:
8.2.1
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.
ENABLING CLOCK SWITCHING
To enable clock switching, the FCKSM1 Configuration
bit in the Configuration register must be programmed to
‘0’. (Refer to Section 20.1 “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.
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.
8.2.2
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, then the
clock switch is a redundant operation. In this
case, the OSWEN bit is cleared automatically
and the clock switch is aborted.
If a valid clock switch has been initiated, the
LOCK
(OSCCON<5>)
and
the
CF
(OSCCON<3>) status bits are cleared.
The new oscillator is turned on by the hardware
if it is not currently running. If a crystal oscillator
must be turned on, the hardware waits until the
Oscillator Start-up Timer (OST) expires. If the
new source is using the PLL, the hardware waits
until a PLL lock is detected (LOCK = 1).
The hardware waits for 10 clock cycles from the
new clock source and then performs the clock
switch.
The hardware clears the OSWEN bit to indicate a
successful clock transition. In addition, the NOSC
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).
2.
3.
4.
5.
6.
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.
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.
8.3
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
This data sheet summarizes the features
of
this
group
of PIC24HJXXXGPX06/X08/X10 devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
“PIC24H Family Reference Manual”.
Refer to the Microchip web site
(www.microchip.com) for the latest
PIC24H Family Reference Manual
sections.
The PIC24HJXXXGPX06/X08/X10 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. PIC24HJXXXGPX06/X08/X10 devices
can manage power consumption in four different ways:
•
•
•
•
Clock frequency
Instruction-based Sleep and Idle modes
Software-controlled Doze mode
Selective peripheral control in software
Combinations of these methods can be used to selectively tailor an application’s power consumption while
still maintaining critical application features, such as
timing-sensitive communications.
9.1
Clock Frequency and Clock
Switching
PIC24HJXXXGPX06/X08/X10 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 8.0 “Oscillator
Configuration”.
9.2
Instruction-Based Power-Saving
Modes
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 9-1.
Note:
SLEEP_MODE and IDLE_MODE are
constants defined in the assembler
include file for the selected device.
Sleep and Idle modes can be exited as a result of an
enabled interrupt, WDT time-out or a device Reset. When
the device exits these modes, it is said to “wake-up”.
9.2.1
SLEEP MODE
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 the
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.
PIC24HJXXXGPX06/X08/X10 devices have two special power-saving modes that are entered through the
execution of a special PWRSAV instruction. Sleep mode

PIC24HJXXXGPX06/X08/X10
9.2.2
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 9.4
“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 begins immediately, starting
with the instruction following the PWRSAV instruction, or
the first instruction in the ISR.
9.2.3
INTERRUPTS COINCIDENT WITH
POWER SAVE INSTRUCTIONS
Any interrupt that coincides with the execution of a
PWRSAV instruction is held off until entry into Sleep or
Idle mode has completed. The device then wakes up
from Sleep or Idle mode.
9.3
Doze Mode
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.
DS70175F-page 128
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.
9.4
Peripheral Module Disable
The Peripheral Module Disable (PMD) registers
provide a method to disable a peripheral module by
stopping all clock sources supplied to that module.
When a peripheral is disabled 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
This data sheet summarizes the features
of
this
group
of PIC24HJXXXGPX06/X08/X10 devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
“PIC24H Family Reference Manual”.
Refer to the Microchip web site
(www.microchip.com) for the latest
PIC24H Family Reference Manual
sections.
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.
10.1
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
which a port’s digital output can drive the input of a
peripheral that shares the same pin. Figure 10-1 shows
how ports are shared with other peripherals and the
associated I/O pin to which they are connected.
FIGURE 10-1:
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’, then the pin
is an input. All port pins are defined as inputs after a
Reset. Reads from the latch (LATx), read the latch.
Writes to the latch, write the latch. Reads from the port
(PORTx), read the port pins, while writes to the port
pins, write the latch.
Any bit and its associated data and control registers
that are not valid for a particular device will be
disabled. That means the corresponding LATx and
TRISx registers and the port pins will read as zeros.
When a pin is shared with another peripheral or function that is defined as an input only, it is nevertheless
regarded as a dedicated port because there is no
other competing source of outputs. An example is the
INT4 pin.
Note:
The voltage on a digital input pin can be
between -0.3V to 5.6V.

10.2
Open-Drain Configuration
In addition to the PORT, LAT and TRIS registers for
data control, each port pin 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 digital only pins by using external pull-up resistors. (The
open-drain I/O feature is not supported on pins that
have analog functionality multiplexed on the pin.) The
maximum open-drain voltage allowed is the same as
the maximum VIH specification. The open-drain output
feature is supported for both port pin and peripheral
configurations.
10.3
Configuring Analog Port Pins
The use of the ADxPCFGH, ADxPCFGL and TRIS
registers control the operation of the A/D 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 A/D modules, if the
corresponding PCFG bit in either
AD1PCFGH(L) and AD2PCFGH(L) is
cleared, the pin is configured as an analog
input.
10.4
I/O Port Write/Read Timing
One instruction cycle is required between a port
direction change or port write operation and a read
operation of the same port. Typically, this instruction
would be a NOP.
10.5
Input Change Notification
The input change notification function of the I/O ports
allows the PIC24HJXXXGPX06/X08/X10 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.
When reading the PORT register, all pins configured as
analog input channels will read as cleared (a low level).
Pins configured as digital inputs will not convert an
analog input. Analog levels on any pin 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).

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.
Note:
To configure Timer2/3, Timer4/5, Timer6/7 or Timer8/9
for 32-bit operation:
1.
2.
3.
As a 32-bit timer, Timer2/3, Timer4/5, Timer6/7 and
Timer8/9 operate in three modes:
4.
• 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
5.
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 12-1. T3CON, T5CON,
T7CON and T9CON are shown in Register 12-2.
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.
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.
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.
To configure any of the timers for individual 16-bit
operation:
1.
2.
3.
4.
5.
6.
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.
A block diagram for a 32-bit timer pair (Timer4/5)
example is shown in Figure 12-1 and a timer (Timer4)
operating in 16-bit mode example is shown in
Figure 12-2.

This data sheet summarizes the features
of this group of PIC24HJXXXGPX06/X08/
X10 devices. It is not intended to be a
comprehensive reference source. To complement the information in this data sheet,

sections.
The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The PIC24HJXXXGPX06/X08/X10 devices support up
to eight input capture channels.
The input capture module captures the 16-bit value of
the selected Time Base register when an event occurs
at the ICx pin. The events that cause a capture event
are listed below in three categories:
1.
2.
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:
Simple Capture Event modes
-Capture timer value on every falling edge of
input at ICx pin
-Capture timer value on every rising edge of
input at ICx pin
Capture timer value on every edge (rising and
falling)
FIGURE 13-1:
Prescaler Capture Event modes
-Capture timer value on every 4th rising edge

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).

OUTPUT COMPARE
This data sheet summarizes the features
of this group of PIC24HJXXXGPX06/X08/
X10 devices. It is not intended to be a
comprehensive reference source. To complement the information in this data sheet,
refer to the “PIC24H Family Reference
Manual”. Refer to the Microchip web site

Setup for Single Output Pulse
Generation
When the OCM control bits (OCxCON<2:0>) are set to
‘100’, the selected output compare channel initializes
the OCx pin to the low state and generates a single
output pulse.
To generate a single output pulse, the following steps
are required (these steps assume timer source is
initially turned off but this is not a requirement for the
module operation):
1. Determine the instruction clock cycle time. Take
into account the frequency of the external clock to
the timer source (if one is used) and the timer
prescaler settings.
2. Calculate time to the rising edge of the output pulse
relative to the TMRy start value (0000h).
3. Calculate the time to the falling edge of the pulse
based on the desired pulse width and the time to the
rising edge of the pulse.
4. Write the values computed in steps 2 and 3 above
into the Output Compare register, OCxR, and the
Output Compare Secondary register, OCxRS,
respectively.
5. Set Timer Period register, PRy, to value equal to or
greater than value in OCxRS, the Output Compare
Secondary register.
6. Set the OCM bits to ‘100’ and the OCTSEL
(OCxCON<3>) bit to the desired timer source. The
OCx pin state will now be driven low.
7. Set the TON (TyCON<15>) bit to ‘1’, which enables
the compare time base to count.
8. Upon the first match between TMRy and OCxR, the
OCx pin will be driven high.
9. When the incrementing timer, TMRy, matches the
Output Compare Secondary register, OCxRS, the
second and trailing edge (high-to-low) of the pulse
is driven onto the OCx pin. No additional pulses are
driven onto the OCx pin and it remains at low. As a
result of the second compare match event, the
OCxIF interrupt flag bit is set, which will result in an
interrupt if it is enabled, by setting the OCxIE bit. For
further information on peripheral interrupts, refer to
Section 6.0 “Interrupt Controller”.
10. To initiate another single pulse output, change the
Timer and Compare register settings, if needed,
and then issue a write to set the OCM bits to ‘100’.
Disabling and re-enabling of the timer, and clear-

ing the TMRy register, are not required but may be
advantageous for defining a pulse from a known
event time boundary.
The output compare module does not have to be disabled after the falling edge of the output pulse. Another
pulse can be initiated by rewriting the value of the
OCxCON register.
14.2
Setup for Continuous Output
Pulse Generation
When the OCM control bits (OCxCON<2:0>) are set to
‘101’, the selected output compare channel initializes
the OCx pin to the low state and generates output
pulses on each and every compare match event.
For the user to configure the module for the generation
of a continuous stream of output pulses, the following
steps are required (these steps assume timer source is
initially turned off but this is not a requirement for the
module operation):
1. Determine the instruction clock cycle time. Take
into account the frequency of the external clock to
the timer source (if one is used) and the timer
prescaler settings.
2. Calculate time to the rising edge of the output pulse
relative to the TMRy start value (0000h).
3. Calculate the time to the falling edge of the pulse,
based on the desired pulse width and the time to the
rising edge of the pulse.
4. Write the values computed in step 2 and 3 above
into the Output Compare register, OCxR, and the
Output Compare Secondary register, OCxRS,
respectively.
5. Set Timer Period register, PRy, to value equal to or
greater than value in OCxRS, the Output Compare
Secondary register.
6. Set the OCM bits to ‘101’ and the OCTSEL bit to the
desired timer source. The OCx pin state will now be
driven low.
7. Enable the compare time base by setting the TON
(TyCON<15>) bit to ‘1’.
8. Upon the first match between TMRy and OCxR, the
OCx pin will be driven high.
9. When the compare time base, TMRy, matches the
Output Compare Secondary register, OCxRS, the
second and trailing edge (high-to-low) of the pulse
is driven onto the OCx pin.
10. As a result of the second compare match event, the
OCxIF interrupt flag bit set.
11. When the compare time base and the value in its
respective Timer Period register match, the TMRy
register resets to 0x0000 and resumes counting.
12. Steps 8 through 11 are repeated and a continuous
stream of pulses is generated, indefinitely. The
OCxIF flag is set on each OCxRS-TMRy compare
match event.

Pulse-Width Modulation Mode
EQUATION 14-1:
The following steps should be taken when configuring
the output compare module for PWM operation:
1.
Set the PWM period by writing to the selected
Timer Period register (PRy).
Set the PWM duty cycle by writing to the OCxRS
register.
Write the OxCR register with the initial duty cycle.
Enable interrupts, if required, for the timer and
output compare modules. The output compare
interrupt is required for PWM Fault pin utilization.
Configure the output compare module for one of
two PWM operation modes by writing to the Output
Compare
Mode
bits,
OCM<2:0>
(OCxCON<2:0>).
Set the TMRy prescale value and enable the
time base by setting TON = 1 (TxCON<15>).
2.
3.
4.
5.
6.
Note:
14.3.1
The OCxR register should be initialized
before the output compare module is first
enabled. The OCxR register becomes a
read-only duty cycle register when the
module is operated in the PWM modes.
The value held in OCxR will become the
PWM duty cycle for the first PWM period.
The contents of the Output Compare
Secondary register, OCxRS, will not be
transferred into OCxR until a time base
period match occurs.
PWM PERIOD
The PWM period is specified by writing to PRy, the
Timer Period register. The PWM period can be
calculated using Equation 14-1:
EQUATION 14-2:
PWM Period = [(PRy) + 1] • TCY • (Timer Prescale Value)
where:
PWM Frequency = 1/[PWM Period]
Note:
14.3.2
2.
PWM DUTY CYCLE
Some important boundary parameters of the PWM duty
cycle include:
• If the Output Compare register, OCxR, is loaded
with 0000h, the OCx pin will remain low (0% duty
cycle).
• If OCxR is greater than PRy (Timer Period register),
the pin will remain high (100% duty cycle).
• If OCxR is equal to PRy, the OCx pin will be low
for one time base count value and high for all
other count values.
See Example 14-1 for PWM mode timing details.
Table 14-1 shows example PWM frequencies and
resolutions for a device operating at 10 MIPS.
CALCULATION FOR MAXIMUM PWM RESOLUTION
Maximum PWM Resolution (bits) =
1.
A PRy value of N will produce a PWM
period of N + 1 time base count cycles. For
example, a value of 7 written into the PRy
register will yield a period consisting of
eight time base cycles.
The PWM duty cycle is specified by writing to the OCxRS
register. The OCxRS register can be written to at any time,
but the duty cycle value is not latched into OCxR until a
match between PRy and TMRy occurs (i.e., the period is
complete). This provides a double buffer for the PWM duty
cycle and is essential for glitchless PWM operation. In the
PWM mode, OCxR is a read-only register.

PWM PERIOD AND DUTY CYCLE CALCULATIONS
Find the Timer Period register value for a desired PWM frequency that is 52.08 kHz, where FCY = 16 MHz and a Timer2
prescaler setting of 1:1.
TCY
= 62.5 ns
PWM Period = 1/PWM Frequency = 1/52.08 kHz = 19.2 μs
PWM Period = (PR2 + 1) • TCY • (Timer2 Prescale Value)
19.2 μs
= (PR2 + 1) • 62.5 ns • 1
PR2

Find the maximum resolution of the duty cycle that can be used with a 52.08 kHz frequency and a 32 MHz device clock rate:
PWM Resolution = log10 (FCY/FPWM)/log102) bits
= (log10 (16 MHz/52.08 kHz)/log102) bits

SERIAL PERIPHERAL
INTERFACE (SPI)
This data sheet summarizes the features
of this group of PIC24HJXXXGPX06/X08/
X10 devices. It is not intended to be a
comprehensive reference source. To complement the information in this data sheet,
refer to the “PIC24H Family Reference
Manual”. Refer to the Microchip web site
(www.microchip.com) for the latest
PIC24H Family Reference Manual
sections.
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, A/D converters, etc. The SPI module
is compatible with SPI and SIOP from Motorola®.
Note:
15.1
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.
Operating Function Description
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.
A series of eight (8) or sixteen (16) clock pulses shift
out bits from the SPIxSR to SDOx pin and simultaneously shift in data from SDIx pin. An interrupt is generated when the transfer is complete and the
corresponding interrupt flag bit (SPI1IF or SPI2IF) is
set. This interrupt can be disabled through an interrupt
enable bit (SPI1IE or SPI2IE).
The receive operation is double-buffered. When a complete byte is received, it is transferred from SPIxSR to
SPIxBUF.
If the receive buffer is full when new data is being transferred from SPIxSR to SPIxBUF, the module will set the
SPIROV bit indicating an overflow condition. The transfer of the data from SPIxSR to SPIxBUF will not be
completed and the new data will be lost. The module
will not respond to SCL transitions while SPIROV is ‘1’,
effectively disabling the module until SPIxBUF is read
by user software.
© 2007 Microchip Technology Inc.
Transmit writes are also double-buffered. The user
writes to SPIxBUF. When the master or slave transfer
is completed, the contents of the shift register (SPIxSR)
are moved to the receive buffer. If any transmit data has
been written to the buffer register, the contents of the
transmit buffer are moved to SPIxSR. The received
data is thus placed in SPIxBUF and the transmit data in
SPIxSR is ready for the next transfer.
Note:
Both the transmit buffer (SPIxTXB) and
the receive buffer (SPIxRXB) are mapped
to the same register address, SPIxBUF.
Note:
Do not perform read-modify-write operations (such as bit-oriented instructions) on
the SPIxBUF register.
The module supports a basic framed SPI protocol while
operating in either Master or Slave mode. A total of four
framed SPI configurations are supported.
The SPI serial interface consists of four pins:
•
•
•
•
SDIx: Serial Data Input
SDOx: Serial Data Output
SCKx: Shift Clock Input or Output
SSx: Active-Low Slave Select or Frame
Synchronization I/O Pulse
The SPI module can be configured to operate using 2,
3 or 4 pins. In the 3-pin mode, SSx is not used. In the
2-pin mode, both SDOx and SSx are not used.
A block diagram of an SPI module is shown in
Figure 15-1. All PIC24HJXXXGPX06/X08/X10 devices
contain two SPI
modules on a single device.
The SPI module contains an 8-word deep FIFO buffer;
the top of the buffer is denoted as SPIxBUF. If DMA
transfers are enabled, the FIFO buffer must be
disabled by clearing the ENHBUF bit (SPIxCON2<0>).
To set up the SPI module for the Master mode of
operation:
1.
2.
3.
4.
5.
If using interrupts:
a) Clear the SPIxIF bit in the respective IFSn
register.
b) Set the SPIxIE bit in the respective IECn
register.
c) Write the SPIxIP bits in the respective IPCn
register to set the interrupt priority.
Write the desired settings to the SPIxCON
register with MSTEN (SPIxCON1<5>) = 1.
Clear the SPIROV bit (SPIxSTAT<6>).
Enable SPI operation by setting the SPIEN bit
(SPIxSTAT<15>).
Write the data to be transmitted to the SPIxBUF
register. Transmission (and reception) will start as
soon as data is written to the SPIxBUF register.

Both SPI1 and SPI2 can trigger a DMA
data transfer. If SPI1 or SPI2 is selected
as the DMA IRQ source, a DMA transfer
occurs when the SPI1IF or SPI2IF bit gets
set as a result of an SPI1 or SPI2 byte or
word transfer.

sections.
16.2
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 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 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.
The PIC24HJXXXGPX06/X08/X10 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.
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.
Each I2C module ‘x’ (x = 1 or 2) offers the following key
features:
16.3
• I2C interface supporting both master and slave
operation.
• I2C Slave mode supports 7 and 10-bit address.
• I2C Master mode supports 7 and 10-bit address.
• 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.
16.1
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 I
•
•
•
2C
operation are supported:
I2C Interrupts
The I2C module generates two interrupt flags, MI2CxIF
(I2C Master Events Interrupt Flag) and SI2CxIF (I2C
Slave Events Interrupt Flag). A separate interrupt is
generated for all I2C error conditions.
16.4
Baud Rate Generator
In I2C Master mode, the reload value for the BRG is
located in the I2CxBRG register. When the BRG is
loaded with this value, the BRG counts down to ‘0’ and
stops until another reload has taken place. If clock arbitration is taking place, for instance, the BRG is reloaded
when the SCLx pin is sampled high.
As per the I2C standard, FSCL may be 100 kHz or
400 kHz. However, the user can specify any baud rate
up to 1 MHz. I2CxBRG values of ‘0’ or ‘1’ are illegal.

I2C Module Addresses
The I2CxADD register contains the Slave mode
addresses. The register is a 10-bit register.
If the A10M bit (I2CxCON<10>) is ‘0’, the address is
interpreted by the module as a 7-bit address. When an
address is received, it is compared to the 7 Least
Significant bits of the I2CxADD register.
If the A10M bit is ‘1’, the address is assumed to be a
10-bit address. When an address is received, it will be
compared with the binary value, ‘11110 A9 A8’
(where A9 and A8 are two Most Significant bits of
I2CxADD). If that value matches, the next address will
be compared with the Least Significant 8 bits of
I2CxADD, as specified in the 10-bit addressing
protocol.

PIC24HJXXXGPX06/X08/X10
16.8
General Call Address Support
The general call address can address all devices.
When this address is used, all devices should, in
theory, respond with an Acknowledgement.
The general call address is one of eight addresses
reserved for specific purposes by the I2C protocol. It
consists of all ‘0’s with R_W = 0.
The general call address is recognized when the General
Call Enable (GCEN) bit is set (I2CxCON<7> = 1). When
the interrupt is serviced, the source for the interrupt can
be checked by reading the contents of the I2CxRCV to
determine if the address was device-specific or a general
call address.
16.9
Automatic Clock Stretch
In Slave modes, the module can synchronize buffer
reads and writes to the master device by clock
stretching.

Hs mode Master codes
Both 10-bit and 7-bit Transmit modes implement clock
stretching by asserting the SCLREL bit after the falling
edge of the ninth clock, if the TBF bit is cleared,
indicating the buffer is empty.

16.6
Slave Address Masking
The I2CxMSK register (Register 16-3) designates
address bit positions as “don’t care” for both 7-bit and
10-bit Address modes. Setting a particular bit location
(= 1) in the I2CxMSK register, causes the slave module
to respond, whether the corresponding address bit
value is a ‘0’ or ‘1’. For example, when I2CxMSK is set
to ‘00100000’, the slave module will detect both
addresses, ‘0000000’ and ‘00100000’.
To enable address masking, the Intelligent Peripheral
Management Interface (IPMI) must be disabled by
clearing the IPMIEN bit (I2CxCON<11>).
16.7
IPMI Support
The control bit, IPMIEN, enables the module to support
the Intelligent Peripheral Management Interface (IPMI).
When this bit is set, the module accepts and acts upon
all addresses.
TRANSMIT CLOCK STRETCHING
In Slave Transmit modes, clock stretching is always
performed, irrespective of the STREN bit. The user’s
ISR must set the SCLREL bit before transmission is
allowed to continue. By holding the SCLx line low, the
user has time to service the ISR and load the contents
of the I2CxTRN before the master device can initiate
another transmit sequence.
16.9.2
RECEIVE CLOCK STRETCHING
The STREN bit in the I2CxCON register can be used to
enable clock stretching in Slave Receive mode. When
the STREN bit is set, the SCLx pin will be held low at
the end of each data receive sequence.
The user’s ISR must set the SCLREL bit before reception is allowed to continue. By holding the SCLx line
low, the user has time to service the ISR and read the
contents of the I2CxRCV before the master device can
initiate another receive sequence. This will prevent
buffer overruns from occurring.
16.10 Software Controlled Clock
Stretching (STREN = 1)
When the STREN bit is ‘1’, the SCLREL bit may be
cleared by software to allow software to control the
clock stretching.
If the STREN bit is ‘0’, a software write to the SCLREL
bit will be disregarded and have no effect on the
SCLREL bit.

16.11 Slope Control
2
The I C standard requires slope control on the SDAx
and SCLx signals for Fast mode (400 kHz). The control
bit, DISSLW, enables the user to disable slew rate control if desired. It is necessary to disable the slew rate
control for 1 MHz mode.
16.12 Clock Arbitration
Clock arbitration occurs when the master deasserts the
SCLx pin (SCLx allowed to float high) during any
receive, transmit or Restart/Stop condition. When the
SCLx pin is allowed to float high, the Baud Rate Generator (BRG) is suspended from counting until the
SCLx pin is actually sampled high. When the SCLx pin
is sampled high, the Baud Rate Generator is reloaded
with the contents of I2CxBRG and begins counting.
This ensures that the SCLx high time will always be at
least one BRG rollover count in the event that the clock
is held low by an external device.
DS70175F-page 156
16.13 Multi-Master Communication, Bus
Collision and Bus Arbitration
Multi-Master mode support is achieved by bus
arbitration. When the master outputs address/data bits
onto the SDAx pin, arbitration takes place when the
master outputs a ‘1’ on SDAx by letting SDAx float high
while another master asserts a ‘0’. When the SCLx pin
floats high, data should be stable. If the expected data
on SDAx is a ‘1’ and the data sampled on the
SDAx pin = 0, then a bus collision has taken place. The
master will set the I2C master events interrupt flag and
reset the master portion of the I2C port to its Idle state.

The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules available in the PIC24HJXXXGPX06/X08/X10 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:
• 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
FIGURE 17-1:
• Hardware Flow Control Option with UxCTS and
UxRTS pins
• Fully Integrated Baud Rate Generator with 16-bit
Prescaler
• Baud Rates Ranging from 1 Mbps to 15 bps at
16 MIPS
• 4-deep First-In-First-Out (FIFO) Transmit Data
Buffer
• 4-Deep FIFO Receive Data Buffer
• Parity, Framing and Buffer Overrun Error Detection

(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 17-1. The UART module consists of the key
important hardware elements:

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).

UART Baud Rate Generator (BRG)
The UART module includes a dedicated 16-bit Baud
Rate Generator. The BRGx register controls the period
of a free-running 16-bit timer. Equation 17-1 shows the
formula for computation of the baud rate with
BRGH = 0.

the baud rate with BRGH = 1.

16 • Baud Rate
FCY denotes the instruction cycle clock
frequency (FOSC/2).

error for the following conditions:

FCY denotes the instruction cycle clock
frequency (FOSC/2).
The maximum baud rate (BRGH = 1) possible is FCY/4
(for BRGx = 0), and the minimum baud rate possible is
FCY/(4 * 65536).
Writing a new value to the BRGx register causes the
BRG timer to be reset (cleared). This ensures the BRG
does not wait for a timer overflow before generating the
new baud rate.
The maximum baud rate (BRGH = 0) possible is
FCY/16 (for BRGx = 0), and the minimum baud rate
possible is FCY/(16 * 65536).

Set up the UART:
a) Write appropriate values for data, parity and
Stop bits.
b) Write appropriate baud rate value to the
BRGx register.
c) Set up transmit and receive interrupt enable
and priority bits.
Enable the UART.
Set the UTXEN bit (causes a transmit interrupt).
Write data byte to lower byte of UxTXREG word.
The value will be immediately transferred to the
Transmit Shift Register (TSR) and the serial bit
stream will start shifting out with the next rising
edge of the baud clock.
Alternately, the data byte may be transferred
while UTXEN = 0, and then the user may set
UTXEN. This will cause the serial bit stream to
begin immediately because the baud clock will
start from a cleared state.
A transmit interrupt will be generated as per
interrupt control bits, UTXISEL<1:0>.

Write UxTXREG as a 16-bit value only.
A word write to UxTXREG triggers the transfer
of the 9-bit data to the TSR. Serial bit stream will
start shifting out with the first rising edge of the
baud clock.
A transmit interrupt will be generated as per the
setting of control bits, UTXISEL<1:0>.

Receiving in 8-bit or 9-bit Data
Mode

“Transmitting in 8-bit Data Mode”).
Enable the UART.
A receive interrupt will be generated when one
or more data characters have been received as
per interrupt control bits, URXISEL<1:0>.
Read the OERR bit to determine if an overrun
error has occurred. The OERR bit must be reset
in software.
Read UxRXREG.
The act of reading the UxRXREG character will move
the next character to the top of the receive FIFO,
including a new set of PERR and FERR values.
17.6
Flow Control Using UxCTS and
UxRTS Pins
UARTx Clear to Send (UxCTS) and Request to Send
(UxRTS) are the two hardware controlled active-low
pins that are associated with the UART module. These
two pins allow the UART to operate in Simplex and
Flow Control modes. They are implemented to control
the transmission and the reception between the Data
Terminal Equipment (DTE). The UEN<1:0> bits in the
UxMODE register configures these pins.
17.7
Infrared Support
The UART module provides two types of infrared UART
support:
• IrDA clock output to support external IrDA
encoder and decoder device (legacy module
support)
• Full implementation of the IrDA encoder and
decoder.
17.7.1
EXTERNAL IrDA SUPPORT – IrDA
CLOCK OUTPUT
To support external IrDA encoder and decoder devices,
the BCLK pin (same as the UxRTS pin) can be
configured to generate the 16x baud clock. With
UEN<1:0> = 11, the BCLK pin will output the 16x baud
clock if the UART module is enabled; it can be used to
support the IrDA codec chip.
17.7.2
BUILT-IN IrDA ENCODER AND
DECODER
The UART has full implementation of the IrDA encoder
and decoder as part of the UART module. The built-in
IrDA encoder and decoder functionality is enabled
using the IREN bit (UxMODE<12>). When enabled
(IREN = 1), the receive pin (UxRX) acts as the input
from the infrared receiver. The transmit pin (UxTX) acts
as the output to the infrared transmitter.

ENHANCED CAN MODULE
This data sheet summarizes the features
of this group of PIC24HJXXXGPX06/X08/
X10 devices. It is not intended to be a
comprehensive reference source. To complement the information in this data sheet,
refer to the “PIC24H Family Reference
Manual”. Refer to the Microchip web site
(www.microchip.com) for the latest
PIC24H Family Reference Manual
sections.
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
PIC24HJXXXGPX06/X08/X10 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
© 2007 Microchip Technology Inc.
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.
18.2
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.

18.3
Modes of Operation
Note:
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.
18.3.1
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
18.3.2
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.
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.
© 2007 Microchip Technology Inc.
18.3.3
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 switches to Disable mode within
this 11-bit period, then this transmission is
aborted and the corresponding TXABT bit
is set and 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.
18.3.4
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.
18.3.5
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.
18.3.6
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.
18.4
18.4.1
Message Reception
RECEIVE BUFFERS
The CAN bus module has up to 32 receive buffers,
located in DMA RAM. The first 8 buffers need to be
configured as receive buffers by clearing the
corresponding TX/RX buffer selection (TXENn) bit in a
CiTRmnCON register. The overall size of the CAN
buffer area in DMA RAM is selectable by the user and
is
defined
by
the
DMABS<2:0>
bits
(CiFCTRL<15:13>). The first 16 buffers can be
assigned to receive filters, while the rest can be used
only as a FIFO buffer.
DS70175F-page 173
PIC24HJXXXGPX06/X08/X10
An additional buffer is always committed to monitoring
the bus for incoming messages. This buffer is called the
Message Assembly Buffer (MAB).
All messages are assembled by the MAB and are transferred to the buffers only if the acceptance filter criterion
are met. When a message is received, the RBIF flag
(CiINTF<1>) will be set. The user would then need to
inspect the CiVEC and/or CiRXFUL1 register to determine which filter and buffer caused the interrupt to get
generated. The RBIF bit can only be set by the module
when a message is received. The bit is cleared by the
user when it has completed processing the message in
the buffer. If the RBIE bit is set, an interrupt will be
generated when a message is received.
18.4.2
FIFO BUFFER MODE
The ECAN module provides FIFO buffer functionality if
the buffer pointer for a filter has a value of ‘1111’. In this
mode, the results of a hit on that buffer will write to the
next available buffer location within the FIFO.
The CiFCTRL register defines the size of the FIFO. The
FSA<4:0> bits in this register define the start of the
FIFO buffers. The end of the FIFO is defined by the
DMABS<2:0> bits if DMA is enabled. Thus, FIFO sizes
up to 32 buffers are supported.
18.4.3
MESSAGE ACCEPTANCE FILTERS
The message acceptance filters and masks are used to
determine if a message in the message assembly
buffer should be loaded into either of the receive buffers. Once a valid message has been received into the
Message Assembly Buffer (MAB), the identifier fields of
the message are compared to the filter values. If there
is a match, that message will be loaded into the
appropriate receive buffer. Each filter is associated with
a buffer pointer (FnBP<3:0>), which is used to link the
filter to one of 16 receive buffers.
18.4.5
RECEIVE ERRORS
The CAN module will detect the following receive
errors:
• Cyclic Redundancy Check (CRC) Error
• Bit Stuffing Error
• Invalid Message Receive Error
These receive errors do not generate an interrupt.
However, the receive error counter is incremented by
one in case one of these errors occur. The RXWAR bit
(CiINTF<9>) indicates that the receive error counter
has reached the CPU warning limit of 96 and an
interrupt is generated.
18.4.6
RECEIVE INTERRUPTS
Receive interrupts can be divided into 3 major groups,
each including various conditions that generate
interrupts:
• Receive Interrupt:
A message has been successfully received and
loaded into one of the receive buffers. This interrupt is activated immediately after receiving the
End-of-Frame (EOF) field. Reading the RXnIF flag
will indicate which receive buffer caused the
interrupt.
• Wake-up Interrupt:
The CAN module has woken up from Disable
mode or the device has woken up from Sleep
mode.
• Receive Error Interrupts:
A receive error interrupt will be indicated by the
ERRIF bit. This bit shows that an error condition
occurred. The source of the error can be determined by checking the bits in the CAN Interrupt
Flag register, CiINTF.
The acceptance filter looks at incoming messages for
the IDE bit (CiTRBnSID<0>) to determine how to compare the identifiers. If the IDE bit is clear, the message
is a standard frame and only filters with the EXIDE bit
(CiRXFnSID<3>) clear are compared. If the IDE bit is
set, the message is an extended frame, and only filters
with the EXIDE bit set are compared.
- Invalid Message Received:
If any type of error occurred during reception of
the last message, an error will be indicated by
the IVRIF bit.
18.4.4
- Receiver Warning:
The RXWAR bit indicates that the receive error
counter (RERRCNT<7:0>) has reached the
warning limit of 96.
MESSAGE ACCEPTANCE FILTER
MASKS
The mask bits essentially determine which bits to apply
the filter to. If any mask bit is set to a zero, then that bit
will automatically be accepted regardless of the filter
bit. There are three programmable acceptance filter
masks associated with the receive buffers. Any of
these three masks can be linked to each filter by selecting the desired mask in the FnMSK<1:0> bits in the
appropriate CiFMSKSELn register.
DS70175F-page 174
- Receiver Overrun:
The RBOVIF bit (CiINTF<2>) indicates that an
overrun condition occurred.
- Receiver Error Passive:
The RXEP bit indicates that the receive error
counter has exceeded the error passive limit of
127 and the module has gone into error passive
state.

PIC24HJXXXGPX06/X08/X10
18.5
18.5.1
Message Transmission
TRANSMIT BUFFERS
The CAN module has up to eight transmit buffers,
located in DMA RAM. These 8 buffers need to be configured as transmit buffers by setting the corresponding
TX/RX buffer selection (TXENn or TXENm) bit in a
CiTRmnCON register. The overall size of the CAN
buffer area in DMA RAM is selectable by the user and
is
defined
by
the
DMABS<2:0>
bits
(CiFCTRL<15:13>).
Each transmit buffer occupies 16 bytes of data. Eight of
the bytes are the maximum 8 bytes of the transmitted
message. Five bytes hold the standard and extended
identifiers and other message arbitration information.
The last byte is unused.
18.5.2
TRANSMIT MESSAGE PRIORITY
Transmit priority is a prioritization within each node of
the pending transmittable messages. There are four
levels of transmit priority. If the TXnPRI<1:0> bits (in
CiTRmnCON) for a particular message buffer are set to
‘11’, that buffer has the highest priority. If the
TXnPRI<1:0> bits for a particular message buffer are
set to ‘10’ or ‘01’, that buffer has an intermediate priority. If the TXnPRI<1:0> bits for a particular message
buffer are ‘00’, that buffer has the lowest priority. If two
or more pending messages have the same priority, the
messages are transmitted in decreasing order of buffer
index.
18.5.3
18.5.4
TRANSMISSION SEQUENCE
To initiate transmission of the message, the TXREQn
bit (in CiTRmnCON) must be set. The CAN bus module
resolves any timing conflicts between the setting of the
TXREQn bit and the Start-of-Frame (SOF), ensuring
that if the priority was changed, it is resolved correctly
before the SOF occurs. When TXREQn is set, the
TXABTn, TXLARBn and TXERRn flag bits are
automatically cleared.
AUTOMATIC PROCESSING OF
REMOTE TRANSMISSION
REQUESTS
If the RTRENn bit (in the CiTRmnCON register) for a
particular transmit buffer is set, the hardware automatically transmits the data in that buffer in response to
remote transmission requests matching the filter that
points to that particular buffer. The user does not need
to manually initiate a transmission in this case.
18.5.5
ABORTING MESSAGE
TRANSMISSION
The system can also abort a message by clearing the
TXREQ bit associated with each message buffer. Setting the ABAT bit (CiCTRL1<12>) will request an abort
of all pending messages. If the message has not yet
started transmission, or if the message started but is
interrupted by loss of arbitration or an error, the abort
will be processed. The abort is indicated when the
module sets the TXABT bit and the TXnIF flag is not
automatically set.
18.5.6
TRANSMISSION ERRORS
The CAN module will detect the following transmission
errors:
• Acknowledge Error
• Form Error
• Bit Error
These transmission errors will not necessarily generate
an interrupt, but are indicated by the transmission error
counter. However, each of these errors will cause the
transmission error counter to be incremented by one.
Once the value of the error counter exceeds the value
of 96, the ERRIF (CiINTF<5>) and the TXWAR bit
(CiINTF<10>) are set. Once the value of the error
counter exceeds the value of 96, an interrupt is
generated and the TXWAR bit in the Interrupt Flag
register is set.
Setting the TXREQn bit simply flags a message buffer
as enqueued for transmission. When the module
detects an available bus, it begins transmitting the
message which has been determined to have the
highest priority.
If the transmission completes successfully on the first
attempt, the TXREQn bit is cleared automatically and
an interrupt is generated if TXnIE was set.
If the message transmission fails, one of the error condition flags will be set and the TXREQn bit will remain
set, indicating that the message is still pending for
transmission. If the message encountered an error
condition during the transmission attempt, the TXERRn
bit will be set and the error condition may cause an
interrupt. If the message loses arbitration during the
transmission attempt, the TXLARBn bit is set. No
interrupt is generated to signal the loss of arbitration.

18.6
TRANSMIT INTERRUPTS
Baud Rate Setting
Transmit interrupts can be divided into 2 major groups,
each including various conditions that generate
interrupts:
All nodes on any particular CAN bus must have the
same nominal bit rate. In order to set the baud rate, the
following parameters have to be initialized:
• Transmit Interrupt:
At least one of the three transmit buffers is empty
(not scheduled) and can be loaded to schedule a
message for transmission. Reading the TXnIF
flags will indicate which transmit buffer is available
and caused the interrupt.
•
•
•
•
•
•
• Transmit Error Interrupts:
A transmission error interrupt will be indicated by
the ERRIF flag. This flag shows that an error condition occurred. The source of the error can be
determined by checking the error flags in the CAN
Interrupt Flag register, CiINTF. The flags in this
register are related to receive and transmit errors.
- Transmitter Warning Interrupt:
The TXWAR bit indicates that the transmit error
counter has reached the CPU warning limit
of 96.
- Transmitter Error Passive:
The TXEP bit (CiINTF<12>) indicates that the
transmit error counter has exceeded the error
passive limit of 127 and the module has gone to
error passive state.
- Bus Off:
The TXBO bit (CiINTF<13>) indicates that the
transmit error counter has exceeded 255 and
the module has gone to the bus off state.
Note:
Both ECAN1 and ECAN2 can trigger a
DMA data transfer. If C1TX, C1RX, C2TX
or C2RX is selected as a DMA IRQ
source, a DMA transfer occurs when the
C1TXIF, C1RXIF, C2TXIF or C2RXIF bit
gets set as a result of an ECAN1 or
ECAN2 transmission or reception.

BIT TIMING
All controllers on the CAN bus must have the same
baud rate and bit length. However, different controllers
are not required to have the same master oscillator
clock. At different clock frequencies of the individual
controllers, the baud rate has to be adjusted by
adjusting the number of time quanta in each segment.
The nominal bit time can be thought of as being divided
into separate non-overlapping time segments. These
segments are shown in Figure 18-2.

Synchronization Segment (Sync Seg)

Phase Segment 1 (Phase1 Seg)
Phase Segment 2 (Phase2 Seg)
The time segments and also the nominal bit time are
made up of integer units of time called time quanta or
TQ. By definition, the nominal bit time has a minimum
of 8 TQ and a maximum of 25 TQ. Also, by definition,
the minimum nominal bit time is 1 μsec corresponding
to a maximum bit rate of 1 MHz.

PRESCALER SETTING
There is a programmable prescaler with integral values
ranging from 1 to 64, in addition to a fixed divide-by-2
for clock generation. The time quantum (TQ) is a fixed
unit of time derived from the oscillator period and is
given by Equation 18-1.
Note:
FCAN must not exceed 40 MHz. If
CANCKS = 0, then FCY must not exceed
20 MHz.

18.6.3
PROPAGATION SEGMENT
This part of the bit time is used to compensate physical
delay times within the network. These delay times consist of the signal propagation time on the bus line and
the internal delay time of the nodes. The Prop Seg can
be programmed from 1 TQ to 8 TQ by setting the
PRSEG<2:0> bits (CiCFG2<2:0>).
18.6.4
PHASE SEGMENTS
The phase segments are used to optimally locate the
sampling of the received bit within the transmitted bit
time. The sampling point is between Phase1 Seg and
Phase2 Seg. These segments are lengthened or shortened by resynchronization. The end of the Phase1 Seg
determines the sampling point within a bit period. The
segment is programmable from 1 TQ to 8 TQ. Phase2
Seg provides delay to the next transmitted data transition. The segment is programmable from 1 TQ to 8 TQ,
or it may be defined to be equal to the greater of
Phase1 Seg or the information processing time (2 TQ).
The Phase1 Seg is initialized by setting bits
SEG1PH<2:0> (CiCFG2<5:3>) and Phase2 Seg is
initialized by setting SEG2PH<2:0> (CiCFG2<10:8>).
The following requirement must be fulfilled while setting
the lengths of the phase segments:
Prop Seg + Phase1 Seg ≥ Phase2 Seg
18.6.5
SAMPLE POINT
The sample point is the point of time at which the bus
level is read and interpreted as the value of that respective bit. The location is at the end of Phase1 Seg. If the
bit timing is slow and contains many TQ, it is possible to
specify multiple sampling of the bus line at the sample
point. The level determined by the CAN bus then corresponds to the result from the majority decision of three
values. The majority samples are taken at the sample
point and twice before with a distance of TQ/2. The
CAN module allows the user to choose between sampling three times at the same point or once at the same
point, by setting or clearing the SAM bit (CiCFG2<6>).

Typically, the sampling of the bit should take place at
about 60-70% through the bit time, depending on the
system parameters.
18.6.6
SYNCHRONIZATION
To compensate for phase shifts between the oscillator
frequencies of the different bus stations, each CAN
controller must be able to synchronize to the relevant
signal edge of the incoming signal. When an edge in
the transmitted data is detected, the logic will compare
the location of the edge to the expected time (Synchronous Segment). The circuit will then adjust the values
of Phase1 Seg and Phase2 Seg. There are two
mechanisms used to synchronize.
18.6.6.1
Hard Synchronization
Hard synchronization is only done whenever there is a
‘recessive’ to ‘dominant’ edge during bus Idle, indicating the start of a message. After hard synchronization,
the bit time counters are restarted with the Sync Seg.
Hard synchronization forces the edge which has
caused the hard synchronization to lie within the
synchronization segment of the restarted bit time. If a
hard synchronization is done, there will not be a
resynchronization within that bit time.
18.6.6.2
Resynchronization
As a result of resynchronization, Phase1 Seg may be
lengthened or Phase2 Seg may be shortened. The
amount of lengthening or shortening of the phase
buffer segment has an upper boundary known as the
synchronization jump width, and is specified by the
SJW<1:0> bits (CiCFG1<7:6>). The value of the synchronization jump width will be added to Phase1 Seg or
subtracted from Phase2 Seg. The resynchronization
jump width is programmable between 1 TQ and 4 TQ.
The following requirement must be fulfilled while setting
the SJW<1:0> bits:
Phase2 Seg > Synchronization Jump Width
Note:
In the register descriptions that follow, ‘i’ in
the register identifier denotes the specific
ECAN module (ECAN1 or ECAN2).
‘n’ in the register identifier denotes the
buffer, filter or mask number.
‘m’ in the register identifier denotes the
word number within a particular CAN data
field.

10-BIT/12-BIT A/D CONVERTER
This data sheet summarizes the features
of
this
group
of PIC24HJXXXGPX06/X08/X10 devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
“PIC24H Family Reference Manual”.
Refer to the Microchip web site
(www.microchip.com) for the latest
PIC24H Family Reference Manual
sections.
A block diagram of the A/D converter is shown in
Figure 19-1.
19.2
The following configuration steps should be performed.
1.
The PIC24HJXXXGPX06/X08/X10 devices have up to
32 A/D input channels. These devices also have up to
2 A/D 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
A/D modules to be configured by the user as either a
10-bit, 4-sample/hold A/D (default configuration) or a
12-bit, 1-sample/hold A/D.
Note:
19.1
The A/D module needs to be disabled
before modifying the AD12B bit.
Key Features
The 10-bit A/D 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 A/D 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.
Depending on the particular device pinout, the A/D 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/D Initialization
2.
Configure the A/D 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<5:0>)
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

19.3
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, then
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
Note:
20.1
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.
This data sheet summarizes the features
of
this
group
of PIC24HJXXXGPX06/X08/X10 devices.
It is not intended to be a comprehensive
reference source. To complement the

The device Configuration register map is shown in
Table 20-1.
The individual Configuration bit descriptions for the
FBS, FSS, FGS, FOSCSEL, FOSC, FWDT and FPOR
Configuration registers are shown in Table 20-1.
PIC24HJXXXGPX06/X08/X10 devices include several
features intended to maximize application flexibility and
reliability, and minimize cost through elimination of
external components. These are:
•
•
•
•

Address
Configuration Bits
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.
The upper byte of all device Configuration registers
should always be ‘1111 1111’. This makes them
appear to be NOP instructions in the remote event that
their locations are ever executed by accident. Since
Configuration bits are not implemented in the
corresponding locations, writing ‘1’s to these locations
has no effect on device operation.
To prevent inadvertent configuration changes during
code execution, all programmable Configuration bits
are write-once. After a bit is initially programmed during
a power cycle, it cannot be written to again. Changing
a device configuration requires that power to the device
be cycled.

PIC24HJXXXGPX06/X08/X10
20.2
On-Chip Voltage Regulator
All of the PIC24HJXXXGPX06/X08/X10 devices power
their core digital logic at a nominal 2.5V. This may create an issue for designs that are required to operate at
a higher typical voltage, such as 3.3V. To simplify system
design,
all
devices
in
the
PIC24HJXXXGPX06/X08/X10 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 VDDCORE/VCAP pin (Figure 20-1).
This helps to maintain the stability of the regulator. The
recommended value for the filter capacitor is provided
in TABLE 23-13: “Internal Voltage Regulator Specifications” located in Section 23.1 “DC Characteristics”.
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.

BOR: Brown-Out Reset
The BOR (Brown-out Reset) module is based on an
internal voltage reference circuit that monitors the regulated voltage VDDCORE. 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 exces
ive 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, then 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, then a nominal delay of TFSCM = 100 ìs 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, if enabled,
continues to operate while in Sleep or Idle modes and
will reset the device should VDD fall below the BOR
threshold voltage.

PIC24HJXXXGPX06/X08/X10
20.4
Watchdog Timer (WDT)
For PIC24HJXXXGPX06/X08/X10 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 20-2:
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
20.8
In-Circuit Debugger
PIC24HJXXXGPX06/X08/X10 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.
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 EMUCx (Emulation/Debug Clock) and
EMUDx (Emulation/Debug Data) pin functions.
20.6
Any 1 out of 3 pairs of debugging clock/data pins may
be used:
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.
• PGC1/EMUC1 and PGD1/EMUD1
• PGC2/EMUC2 and PGD2/EMUD2
• PGC3/EMUC3 and PGD3/EMUD3
To use the in-circuit debugger function of the device,
the design must implement ICSP programming capability connections to MCLR, VDD, VSS, PGC, PGD and
the EMUDx/EMUCx pin pair. In addition, when the feature is enabled, some of the resources are not available
for general use. These resources include the first 80
bytes of data RAM and two I/O pins.
The code protection features are controlled by the
Configuration registers: FBS, FSS and FGS.
Note:
20.7
Refer to CodeGuard Security Reference
Manual (DS70180) for further information
on usage, configuration and operation of
CodeGuard Security.
In-Circuit Serial Programming
Programming Capability
PIC24HJXXXGPX06/X08/X10 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 Flash Programming Specification” (DS70152) document for
details about ICSP
programming capability.
Any 1 out of 3 pairs of programming clock/data pins
may be used:
• PGC1/EMUC1 and PGD1/EMUD1
• PGC2/EMUC2 and PGD2/EMUD2
• PGC3/EMUC3 and PGD3/EMUD3

INSTRUCTION SET SUMMARY
This data sheet summarizes the features
of this group of PIC24HJXXXGPX06/X08/
X10 devices. It is not intended to be a
comprehensive reference source. To complement the information in this data sheet,
refer to the “PIC24H Family Reference
Manual”. Refer to the Microchip web site
(www.microchip.com) for the latest
PIC24H Family Reference Manual
sections.
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
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
Table 21-1 shows the general symbols used in
describing the instructions.
The PIC24H instruction set summary in Table 21-2 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’

PIC24HJXXXGPX06/X08/X10
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
TABLE 21-1:
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.
Note:
For more details on the instruction set,
refer to the “dsPIC30F/33F Programmer’s
Reference Manual” (DS70157).

22.6
MPLAB SIM Software Simulator
The MPLAB SIM Software Simulator allows code
development in a PC-hosted environment by simulating the PIC MCUs and dsPIC® DSCs on an instruction
level. On any given instruction, the data areas can be
examined or modified and stimuli can be applied from
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 C18 and
MPLAB C30 C Compilers, and the MPASM and
MPLAB ASM30 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.
The MPLIB Object Librarian manages the creation and
modification of library files of precompiled code. When
a routine from a library is called from a source file, only
the modules that contain that routine will be linked in
with the application. This allows large libraries to be
used efficiently in many different applications.
The object linker/library features include:
• Efficient linking of single libraries instead of many
smaller files
• Enhanced code maintainability by grouping
related modules together
• Flexible creation of libraries with easy module
listing, replacement, deletion and extraction

Data in “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.

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.
