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.

Microchip received ISO/TS-16949:2002 certification for its worldwide

headquarters, design and wafer fabrication facilities in Chandler and

Tempe, Arizona; Gresham, Oregon and design centers in California

and India. The Company’s quality system processes and procedures

are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hopping

devices, Serial EEPROMs, microperipherals, nonvolatile memory and

analog products. In addition, Microchip’s quality system for the design

and manufacture of development systems is ISO 9001:2000 certified.

1.0 DEVICE OVERVIEW

This document contains device specific information for

the following devices:

• PIC24HJ64GP206A

• PIC24HJ64GP210A

• PIC24HJ64GP506A

• PIC24HJ64GP510A

• PIC24HJ128GP206A

• PIC24HJ128GP210A

• PIC24HJ256GP206A

• PIC24HJ256GP210A

• PIC24HJ256GP610A

The PIC24HJXXXGPX06A/X08A/X10A device family

includes devices with different pin counts (64 and 100

pins), different program memory sizes (64 Kbytes, 128

Kbytes and 256 Kbytes) and different RAM sizes (8

Kbytes and 16 Kbytes).

This makes these families suitable for a wide variety of

high-performance digital signal control applications.

The devices are pin compatible with the dsPIC33F fam-

ily 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, computa-

tional resource and system cost requirements of the

application.

The PIC24HJXXXGPX06A/X08A/X10A device family

employs a powerful 16-bit architecture, ideal for

applications that rely on high-speed, repetitive

computations, as well as control.

The 17 x 17 multiplier, hardware support for division

operations, multi-bit data shifter, a large array of 16-bit

working registers and a wide variety of data addressing

modes, together provide the

PIC24HJXXXGPX06A/X08A/X10A Central Processing

Unit (CPU) with extensive mathematical processing

capability. Flexible and deterministic interrupt handling,

coupled with a powerful array of peripherals, renders

the PIC24HJXXXGPX06A/X08A/X10A devices suit-

able for control applications. Further, Direct Memory

Access (DMA) enables overhead-free transfer of data

between several peripherals and a dedicated DMA

RAM. Reliable, field programmable Flash program

memory ensures scalability of applications that use

PIC24HJXXXGPX06A/X08A/X10A devices.

Figure 1-1 shows a general block diagram of the

various core and peripheral modules in the

PIC24HJXXXGPX06A/X08A/X10A family of devices,

while Ta b le 1-1 lists the functions of the various pins

shown in the pinout diagrams.

Note: This data sheet summarizes the features

of the PIC24HJXXXGPX06A/X08A/X10A

family of devices. However, it is not

intended to be a comprehensive refer-

ence source. To complement the informa-

tion in this data sheet, refer to the latest

family reference sections of the

2.2 Decoupling Capacitors

The use of decoupling capacitors on every pair of

power supply pins, such as VDD, VSS, AVDD and

AVSS is required.

Consider the following criteria when using decoupling

capacitors:

•Value and type of capacitor: Recommendation

of 0.1 µF (100 nF), 10-20V. This capacitor should

be a low-ESR and have resonance frequency in

the range of 20 MHz and higher. It is

recommended that ceramic capacitors be used.

•Placement on the printed circuit board: The

decoupling capacitors should be placed as close

to the pins as possible. It is recommended to

place the capacitors on the same side of the

board as the device. If space is constricted, the

capacitor can be placed on another layer on the

PCB using a via; however, ensure that the trace

length from the pin to the capacitor is within

one-quarter inch (6 mm) in length.

•Handling high frequency noise: If the board is

experiencing high frequency noise, upward of

tens of MHz, add a second ceramic-type capaci-

tor in parallel to the above described decoupling

capacitor. The value of the second capacitor can

be in the range of 0.01 µF to 0.001 µF. Place this

second capacitor next to the primary decoupling

capacitor. In high-speed circuit designs, consider

implementing a decade pair of capacitances as

close to the power and ground pins as possible.

For example, 0.1 µF in parallel with 0.001 µF.

•Maximizing performance: On the board layout

from the power supply circuit, run the power and

return traces to the decoupling capacitors first,

and then to the device pins. This ensures that the

decoupling capacitors are first in the power chain.

Equally important is to keep the trace length

between the capacitor and the power pins to a

minimum thereby reducing PCB track inductance.

of the PIC24HJXXXGPX06A/X08A/X10A

family of devices. It is not intended to be

a comprehensive reference source. To

described in this section may not be

available on all devices. Refer to

Section 4.0 “Memory Organization” in

this data sheet for device-specific register

and bit information.

Note: The AVDD and AVSS pins must be

connected independent of the ADC

voltage reference source.

MINIMUM CONNECTION

2.2.1 TANK CAPACITORS

On boards with power traces running longer than six

inches in length, it is suggested to use a tank capacitor

for integrated circuits including MCUs to supply a local

power source. The value of the tank capacitor should

be determined based on the trace resistance that con-

nects the power supply source to the device, and the

maximum current drawn by the device in the applica-

tion. In other words, select the tank capacitor so that it

meets the acceptable voltage sag at the device. Typical

values range from 4.7 µF to 47 µF.

2.3 CPU Logic Filter Capacitor

Connection (VCAP)

A low-ESR (< 5 Ohms) capacitor is required on the

VCAP pin, which is used to stabilize the voltage

regulator output voltage. The VCAP pin must not be

connected to VDD, and must have a capacitor between

4.7 µF and 10 µF, 16V connected to ground. The type

can be ceramic or tantalum. Refer to Section 24.0

“Electrical Characteristics” for additional

information.

The placement of this capacitor should be close to the

VCAP. It is recommended that the trace length not

exceed one-quarter inch (6 mm). Refer to Section 21.2

“On-Chip Voltage Regulator” for details.

2.4 Master Clear (MCLR) Pin

The MCLR pin provides for two specific device

functions:

• Device Reset

• Device programming and debugging

During device programming and debugging, the

resistance and capacitance that can be added to the

pin must be considered. Device programmers and

debuggers drive the MCLR pin. Consequently,

specific voltage levels (VIH and VIL) and fast signal

transitions must not be adversely affected. Therefore,

specific values of R and C will need to be adjusted

based on the application and PCB requirements.

For example, as shown in Figure 2-2, it is

recommended that the capacitor C, be isolated from

the MCLR pin during programming and debugging

operations.

Place the components shown in Figure 2-2 within

one-quarter inch (6 mm) from the MCLR pin.

2.5 ICSP Pins

The PGECx and PGEDx pins are used for In-Circuit

Serial Programming™ (ICSP™) and debugging pur-

poses. It is recommended to keep the trace length

between the ICSP connector and the ICSP pins on the

device as short as possible. If the ICSP connector is

expected to experience an ESD event, a series resistor

is recommended, with the value in the range of a few

tens of Ohms, not to exceed 100 Ohms.

Pull-up resistors, series diodes, and capacitors on the

PGECx and PGEDx pins are not recommended as they

will interfere with the programmer/debugger communi-

cations to the device. If such discrete components are

an application requirement, they should be removed

from the circuit during programming and debugging.

Alternatively, refer to the AC/DC characteristics and

timing requirements information in the respective

device Flash programming specification for information

on capacitive loading limits and pin input voltage high

(VIH) and input low (VIL) requirements.

Ensure that the “Communication Channel Select” (i.e.,

PGECx/PGEDx pins) programmed into the device

matches the physical connections for the ICSP to

MPLAB® ICD 2, MPLAB ICD 3 or MPLAB REAL ICE™.

For more information on ICD 2, ICD 3 and REAL ICE

connection requirements, refer to the following

documents that are available on the Microchip website.

Guide” DS51331

2.6 External Oscillator Pins

Many MCUs have options for at least two oscillators: a

high-frequency primary oscillator and a low-frequency

secondary oscillator (refer to Section 9.0 “Oscillator

Configuration” for details).

The oscillator circuit should be placed on the same

side of the board as the device. Also, place the

oscillator circuit close to the respective oscillator pins,

not exceeding one-half inch (12 mm) distance

between them. The load capacitors should be placed

next to the oscillator itself, on the same side of the

board. Use a grounded copper pour around the

oscillator circuit to isolate them from surrounding

circuits. The grounded copper pour should be routed

directly to the MCU ground. Do not run any signal

traces or power traces inside the ground pour. Also, if

using a two-sided board, avoid any traces on the

other side of the board where the crystal is placed. A

suggested layout is shown in Figure 2-3.

2.7 Oscillator Value Conditions on

Device Start-up

If the PLL of the target device is enabled and

configured for the device start-up oscillator, the

maximum oscillator source frequency must be limited

to ≤8 MHz for start-up with PLL enabled to comply with

device PLL start-up conditions. This means that if the

external oscillator frequency is outside this range, the

application must start-up in the FRC mode first. The

default PLL settings after a POR with an oscillator

frequency outside this range will violate the device

operating speed.

Once the device powers up, the application firmware

can initialize the PLL SFRs, CLKDIV and PLLDBF to a

suitable value, and then perform a clock switch to the

Oscillator + PLL clock source. Note that clock switching

must be enabled in the device Configuration word.

2.8 Configuration of Analog and

Digital Pins During ICSP

Operations

If MPLAB ICD 2, ICD 3 or REAL ICE is selected as a

debugger, it automatically initializes all of the A/D input

pins (ANx) as “digital” pins, by setting all bits in the

AD1PCFGL register.

The bits in this register that correspond to the A/D pins

that are initialized by MPLAB ICD 2, ICD 3, or REAL

ICE, must not be cleared by the user application

firmware; otherwise, communication errors will result

between the debugger and the device.

If your application needs to use certain A/D pins as

analog input pins during the debug session, the user

application must clear the corresponding bits in the

AD1PCFGL register during initialization of the ADC

module.

When MPLAB ICD 2, ICD 3 or REAL ICE is used as a

programmer, the user application firmware must

correctly configure the AD1PCFGL register. Automatic

initialization of this register is only done during

debugger operation. Failure to correctly configure the

analog input pins, resulting in the port value being read

as a logic ‘0’, which may affect user application

functionality.

2.9 Unused I/Os

Unused I/O pins should be configured as outputs and

driven to a logic-low state.

Alternatively, connect a 1k to 10k resistor between VSS

and the unused pins.

PIC24HJXXXGPX06A/X08A/X10A

3.0 CPU

The PIC24HJXXXGPX06A/X08A/X10A CPU module

has a 16-bit (data) modified Harvard architecture with an

enhanced instruction set and addressing modes. The

CPU has a 24-bit instruction word with a variable length

opcode field. The Program Counter (PC) is 23 bits wide

and addresses up to 4M x 24 bits of user program

memory space. The actual amount of program memory

implemented varies by device. A single-cycle instruction

prefetch mechanism is used to help maintain throughput

and provides predictable execution. All instructions

execute in a single cycle, with the exception of

instructions that change the program flow, the double

word move (MOV.D) instruction and the table instructions.

Overhead-free, single-cycle program loop constructs are

supported using the REPEAT instruction, which is

interruptible at any point.

The PIC24HJXXXGPX06A/X08A/X10A devices have

sixteen, 16-bit working registers in the programmer’s

model. Each of the working registers can serve as a data,

address or address offset register. The 16th working

for interrupts and calls.

The PIC24HJXXXGPX06A/X08A/X10A instruction set

includes many addressing modes and is designed for

optimum C compiler efficiency. For most instructions,

the PIC24HJXXXGPX06A/X08A/X10A is capable of

executing a data (or program data) memory read, a

working register (data) read, a data memory write and

a program (instruction) memory read per instruction

cycle. As a result, three parameter instructions can be

supported, allowing A + B = C operations to be

executed in a single cycle.

A block diagram of the CPU is shown in Figure 3-1,

and the programmer’s model for the

PIC24HJXXXGPX06A/X08A/X10A is shown in

Figure 3-2.

3.1 Data Addressing Overview

The data space can be linearly addressed as 32K words

or 64 Kbytes using an Address Generation Unit (AGU).

The upper 32 Kbytes of the data space memory map can

optionally be mapped into program space at any 16K

program word boundary defined by the 8-bit Program

Space Visibility Page (PSVPAG) register. The program to

data space mapping feature lets any instruction access

program space as if it were data space.

The data space also includes 2 Kbytes of DMA RAM,

which is primarily used for DMA data transfers, but may

be used as general purpose RAM.

3.2 Special MCU Features

The PIC24HJXXXGPX06A/X08A/X10A features a

17-bit by 17-bit, single-cycle multiplier. The multiplier

can perform signed, unsigned and mixed-sign

multiplication. Using a 17-bit by 17-bit multiplier for

16-bit by 16-bit multiplication makes mixed-sign

multiplication possible.

The PIC24HJXXXGPX06A/X08A/X10A supports 16/16

and 32/16 integer divide operations. All divide

instructions are iterative operations. They must be

executed within a REPEAT loop, resulting in a total

execution time of 19 instruction cycles. The divide

operation can be interrupted during any of those

19 cycles without loss of data.

A multi-bit data shifter is used to perform up to a 16-bit,

left or right shift in a single cycle.

PIC24HJXXXGPX06A/X08A/X10A

3.4 Arithmetic Logic Unit (ALU)

The PIC24HJXXXGPX06A/X08A/X10A ALU is 16 bits

wide and is capable of addition, subtraction, bit shifts

and logic operations. Unless otherwise mentioned,

arithmetic operations are 2’s complement in nature.

Depending on the operation, the ALU may affect the

values of the Carry (C), Zero (Z), Negative (N),

Overflow (OV) and Digit Carry (DC) Status bits in the

SR register. The C and DC Status bits operate as

Borrow and Digit Borrow bits, respectively, for

subtraction operations.

The ALU can perform 8-bit or 16-bit operations,

depending on the mode of the instruction that is used.

Data for the ALU operation can come from the W reg-

ister array, or data memory, depending on the address-

ing mode of the instruction. Likewise, output data from

the ALU can be written to the W register array or a data

memory location.

Refer to the “16-bit MCU and DSC Programmer’s

Reference Manual” (DS70157) for information on the

SR bits affected by each instruction.

The PIC24HJXXXGPX06A/X08A/X10A CPU

incorporates hardware support for both multiplication

and division. This includes a dedicated hardware

multiplier and support hardware for 16-bit divisor

division.

3.4.1 MULTIPLIER

Using the high-speed 17-bit x 17-bit multiplier, the ALU

supports unsigned, signed or mixed-sign operation in

several multiplication modes:

• 16-bit x 16-bit signed

• 16-bit x 16-bit unsigned

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

• 16-bit unsigned x 16-bit unsigned

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

• 16-bit unsigned x 16-bit signed

• 8-bit unsigned x 8-bit unsigned

3.4.2 DIVIDER

The divide block supports 32-bit/16-bit and 16-bit/16-bit

signed and unsigned integer divide operations with the

following data sizes:

• 32-bit signed/16-bit signed divide

• 32-bit unsigned/16-bit unsigned divide

• 16-bit signed/16-bit signed divide

• 16-bit unsigned/16-bit unsigned divide

The quotient for all divide instructions ends up in W0

and the remainder in W1. Sixteen-bit signed and

unsigned DIV instructions can specify any W register

for both the 16-bit divisor (Wn) and any W register

(aligned) pair (W(m + 1):Wm) for the 32-bit dividend.

The divide algorithm takes one cycle per bit of divisor,

so both 32-bit/16-bit and 16-bit/16-bit instructions take

the same number of cycles to execute.

3.4.3 MULTI-BIT DATA SHIFTER

The multi-bit data shifter is capable of performing up to

16-bit arithmetic or logic right shifts, or up to 16-bit left

shifts in a single cycle. The source can be either a

working register or a memory location.

The shifter requires a signed binary value to determine

both the magnitude (number of bits) and direction of the

shift operation. A positive value shifts the operand right.

A negative value shifts the operand left. A value of ‘0’

does not modify the operand.

PIC24HJXXXGPX06A/X08A/X10A

4.0 MEMORY ORGANIZATION

The PIC24HJXXXGPX06A/X08A/X10A architecture

features separate program and data memory spaces

and buses. This architecture also allows the direct

access of program memory from the data space during

code execution.

4.1 Program Address Space

The program address memory space of the

PIC24HJXXXGPX06A/X08A/X10A devices is 4M

instructions. The space is addressable by a 24-bit value

derived from either the 23-bit Program Counter (PC)

during program execution, or from table operation or

data space remapping as described in Section 4.4

“Interfacing Program and Data Memory Spaces”.

User access to the program memory space is restricted

to the lower half of the address range (0x000000 to

0x7FFFFF). The exception is the use of TBLRD/TBLWT

operations, which use TBLPAG<7> to permit access to

the Configuration bits and Device ID sections of the

configuration memory space.

Memory maps for the PIC24HJXXXGPX06A/X08A/

X10A family of devices are shown in Figure 4-1.

4.1.1 PROGRAM MEMORY

ORGANIZATION

The program memory space is organized in word-

addressable blocks. Although it is treated as 24 bits

wide, it is more appropriate to think of each address of

the program memory as a lower and upper word, with

the upper byte of the upper word being unimplemented.

The lower word always has an even address, while the

upper word has an odd address (Figure 4-2).

Program memory addresses are always word-aligned

on the lower word, and addresses are incremented or

decremented by two during code execution. This

arrangement also provides compatibility with data

memory space addressing and makes it possible to

access data in the program memory space.

4.1.2 INTERRUPT AND TRAP VECTORS

All PIC24HJXXXGPX06A/X08A/X10A devices reserve

the addresses between 0x00000 and 0x000200 for

hard-coded program execution vectors. A hardware

Reset vector is provided to redirect code execution

from the default value of the PC on device Reset to the

actual start of code. A GOTO instruction is programmed

by the user at 0x000000, with the actual address for the

start of code at 0x000002.

PIC24HJXXXGPX06A/X08A/X10A devices also have

two interrupt vector tables, located from 0x000004 to

0x0000FF and 0x000100 to 0x0001FF. These vector

tables allow each of the many device interrupt sources

to be handled by separate Interrupt Service Routines

(ISRs). A more detailed discussion of the interrupt vec-

tor tables is provided in Section 7.1 “Interrupt Vector

4.2 Data Address Space

The PIC24HJXXXGPX06A/X08A/X10A CPU has a

separate 16-bit wide data memory space. The data

space is accessed using separate Address Generation

Units (AGUs) for read and write operations. Data mem-

ory maps of devices with different RAM sizes are

shown in Figure 4-3 and Figure 4-4.

All Effective Addresses (EAs) in the data memory space

are 16 bits wide and point to bytes within the data space.

This arrangement gives a data space address range of

64 Kbytes or 32K words. The lower half of the data

memory space (that is, when EA<15> = 0) is used for

implemented memory addresses, while the upper half

(EA<15> = 1) is reserved for the Program Space

Visibility area (see Section 4.4.3 “Reading Data from

Program Memory Using Program Space Visibility”).

PIC24HJXXXGPX06A/X08A/X10A devices implement

up to 16 Kbytes of data memory. Should an EA point to

a location outside of this area, an all-zero word or byte

will be returned.

4.2.1 DATA SPACE WIDTH

The data memory space is organized in byte address-

able, 16-bit wide blocks. Data is aligned in data

memory and registers as 16-bit words, but all data

space EAs resolve to bytes. The Least Significant

Bytes of each word have even addresses, while the

Most Significant Bytes have odd addresses.

4.2.2 DATA MEMORY ORGANIZATION

AND ALIGNMENT

To maintain backward compatibility with PIC® MCU

devices and improve data space memory usage

efficiency, the PIC24HJXXXGPX06A/X08A/X10A

instruction set supports both word and byte operations.

As a consequence of byte accessibility, all effective

address calculations are internally scaled to step

through word-aligned memory. For example, the core

recognizes that Post-Modified Register Indirect

Addressing mode [Ws++] will result in a value of Ws +

1 for byte operations and Ws + 2 for word operations.

Data byte reads will read the complete word that

contains the byte, using the Least Significant bit (LSb)

of any EA to determine which byte to select. The

selected byte is placed onto the Least Significant Byte

(LSB) of the data path. That is, data memory and reg-

isters 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.

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 opera-

tions, or translating from 8-bit MCU code. If a mis-

aligned 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, allow-

ing the system and/or user to examine the machine

state prior to execution of the address Fault.

All byte loads into any W register are loaded into the

Least Significant Byte. The Most Significant Byte

(MSB) is not modified.

A sign-extend instruction (SE) is provided to allow

users to translate 8-bit signed data to 16-bit signed

values. Alternatively, for 16-bit unsigned data, users

can clear the Most Significant Byte of any W register by

executing a zero-extend (ZE) instruction on the

appropriate address.

4.2.3 SFR SPACE

The first 2 Kbytes of the Near Data Space, from 0x0000

to 0x07FF, is primarily occupied by Special Function

Registers (SFRs). These are used by the

PIC24HJXXXGPX06A/X08A/X10A core and peripheral

modules for controlling the operation of the device.

SFRs are distributed among the modules that they

control, and are generally grouped together by module.

Much of the SFR space contains unused addresses;

these are read as ‘0’. A complete listing of implemented

SFRs, including their addresses, is shown in Table 4-1

through Ta b l e 4 - 3 3 .

4.2.4 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

Note: 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.

4.2.5 DMA RAM

Every PIC24HJXXXGPX06A/X08A/X10A device

contains 2 Kbytes of dual ported DMA RAM located at

the end of data space. Memory locations in the DMA

RAM space are accessible simultaneously by the CPU

and the DMA controller module. DMA RAM is utilized by

the DMA controller to store data to be transferred to

various peripherals using DMA, as well as data

transferred from various peripherals using DMA. The

DMA RAM can be accessed by the DMA controller

without having to steal cycles from the CPU.

When the CPU and the DMA controller attempt to

concurrently write to the same DMA RAM location, the

hardware ensures that the CPU is given precedence in

accessing the DMA RAM location. Therefore, the DMA

RAM provides a reliable means of transferring DMA

data without ever having to stall the CPU.

4.2.6 SOFTWARE STACK

In addition to its use as a working register, the W15

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 4-5. For a PC push

during any CALL instruction, the MSB of the PC is zero-

extended before the push, ensuring that the MSB is

always clear.

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.

4.2.7 DATA RAM PROTECTION FEATURE

The PIC24H product family supports Data RAM protec-

tion 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 Seg-

ment Flash code, when enabled. SSRAM (Secure

Secure Segment Flash code, when enabled. See

Table 4-1 for an overview of the BSRAM and SSRAM

SFRs.

4.3 Instruction Addressing Modes

The addressing modes in Ta b l e 4 -3 4 form the basis of

the addressing modes optimized to support the specific

features of individual instructions. The addressing

modes provided in the MAC class of instructions are

somewhat different from those in the other instruction

types.

4.3.1 FILE REGISTER INSTRUCTIONS

Most file register instructions use a 13-bit address field

(f) to directly address data present in the first 8192

bytes of data memory (Near Data Space). Most file

which is denoted as WREG in these instructions. The

destination is typically either the same file register or

WREG (with the exception of the MUL instruction),

which writes the result to a register or register pair. The

MOV instruction allows additional flexibility and can

access the entire data space.

4.3.2 MCU INSTRUCTIONS

The 3-operand MCU instructions are of the form:

Operand 3 = Operand 1 <function> Operand 2

where:

Operand 1 is always a working register (i.e., the

addressing mode can only be Register Direct) which is

referred to as Wb.

Operand 2 can be a W register, fetched from data

memory, or a 5-bit literal. The result location can be

either a W register or a data memory location. The fol-

lowing 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: A PC push during exception processing

concatenates the SRL register to the MSB

of the PC prior to the push.

Note: Not all instructions support all the

Individual instructions may support

different subsets of these addressing

modes.

TABLE 4-34: FUNDAMENTAL ADDRESSING MODES SUPPORTED

4.3.3 MOVE INSTRUCTIONS

Move instructions provide a greater degree of address-

ing flexibility than other instructions. In addition to the

Addressing modes supported by most MCU instruc-

tions, move instructions also support Register Indirect

with Register Offset Addressing mode, also referred to

as Register Indexed mode.

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

4.3.4 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 oper-

and or result is implied by the opcode itself. Certain

operations, such as NOP, do not have any operands.

4.4 Interfacing Program and Data

Memory Spaces

The PIC24HJXXXGPX06A/X08A/X10A architecture

uses a 24-bit wide program space and a 16-bit wide

data space. The architecture is also a modified Harvard

scheme, meaning that data can also be present in the

program space. To use this data successfully, it must

be accessed in a way that preserves the alignment of

information in both spaces.

Aside from normal execution, the

PIC24HJXXXGPX06A/X08A/X10A architecture pro-

vides 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 remap-

ping method allows an application to access a large

block of data on a read-only basis, which is ideal for

look ups from a large table of static data. It can only

access the least significant word of the program word.

4.4.1 ADDRESSING PROGRAM SPACE

Since the address ranges for the data and program

spaces are 16 and 24 bits, respectively, a method is

needed to create a 23-bit or 24-bit program address

from 16-bit data registers. The solution depends on the

interface method to be used.

For table operations, the 8-bit Table Page register

(TBLPAG) is used to define a 32K word region within

the program space. This is concatenated with a 16-bit

EA to arrive at a full 24-bit program space address. In

this format, the Most Significant bit of TBLPAG is used

to determine if the operation occurs in the user memory

(TBLPAG<7> = 0) or the configuration memory

(TBLPAG<7> = 1).

Addressing Mode Description

File Register Direct The address of the file register is specified explicitly.

decremented) by a constant value.

to form the EA.

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).

Note: Not all instructions support all the

Addressing modes given above.

Individual instructions may support

different subsets of these Addressing

modes.

PIC24HJXXXGPX06A/X08A/X10A

For remapping operations, the 8-bit Program Space

Visibility register (PSVPAG) is used to define a

16K word page in the program space. When the Most

Significant bit of the EA is ‘1’, PSVPAG is concatenated

with the lower 15 bits of the EA to form a 23-bit program

space address. Unlike table operations, this limits

remapping operations strictly to the user memory area.

Table 4-35 and Figure 4-6 show how the program EA is

created for table operations and remapping accesses

from the data EA. Here, P<23:0> refers to a program

space word, whereas D<15:0> refers to a data space

word.

4.4.2 DATA ACCESS FROM PROGRAM

MEMORY USING TABLE

INSTRUCTIONS

The TBLRDL and TBLWTL instructions offer a direct

method of reading or writing the lower word of any

address within the program space without going

through data space. The TBLRDH and TBLWTH instruc-

tions 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>).

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’.

2. TBLRDH (Table Read High): In Word mode, it

maps the entire upper word of a program address

(P<23:16>) to a data address. Note that

D<15:8>, the ‘phantom byte’, will always be ‘0’.

In Byte mode, it maps the upper or lower byte of

the program word to D<7:0> of the data

address, as above. Note that the data will

always be ‘0’ when the upper ‘phantom’ byte is

selected (Byte Select = 1).

In a similar fashion, two table instructions, TBLWTH

and TBLWTL, are used to write individual bytes or

words to a program space address. The details of

their operation are explained in Section 5.0 “Flash

Program Memory”.

For all table operations, the area of program memory

space to be accessed is determined by the Table Page

memory space of the device, including user and config-

uration 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.

4.4.3 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 con-

stant 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

16K words in program space. In effect, PSVPAG func-

tions as the upper 8 bits of the program memory

address, with the 15 bits of the EA functioning as the

lower bits. Note that by incrementing the PC by 2 for

each program memory word, the lower 15 bits of data

space addresses directly map to the lower 15 bits in the

corresponding program space addresses.

Data reads to this area add an additional cycle to the

instruction being executed, since two program memory

fetches are required.

Although each data space address, 0x8000 and higher,

maps directly into a corresponding program memory

address (see Figure 4-8), only the lower 16 bits of the

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.

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.

table reads/writes.

5.0 FLASH PROGRAM MEMORY

The PIC24HJXXXGPX06A/X08A/X10A devices con-

tain 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. In-Circuit Serial Programming™ (ICSP™)

programming capability

2. Run-Time Self-Programming (RTSP)

ICSP programming capability allows a

PIC24HJXXXGPX06A/X08A/X10A device to be seri-

ally programmed while in the end application circuit.

This is simply done with two lines for programming

clock and programming data (one of the alternate pro-

gramming pin pairs: PGECx/PGEDx, 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 dig-

ital signal controller just before shipping the product.

This also allows the most recent firmware or a custom

firmware to be programmed.

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.

5.1 Table Instructions and Flash

Programming

Regardless of the method used, all programming of

Flash memory is done with the table read and table

write instructions. These allow direct read and write

access to the program memory space from the data

memory while the device is in normal operating mode.

The 24-bit target address in the program memory is

formed using bits<7:0> of the TBLPAG register and the

Effective Address (EA) from a W register specified in

the table instruction, as shown in Figure 5-1.

The TBLRDL and the TBLWTL instructions are used to

read or write to bits<15:0> of program memory.

TBLRDL and TBLWTL can access program memory in

both Word and Byte modes.

The TBLRDH and TBLWTH instructions are used to read

or write to bits<23:16> of program memory. TBLRDH

and TBLWTH can also access program memory in Word

or Byte mode.

5.2 RTSP Operation

The PIC24HJXXXGPX06A/X08A/X10A Flash program

memory array is organized into rows of 64 instructions

or 192 bytes. RTSP allows the user to erase a page of

memory, which consists of eight rows (512 instructions)

at a time, and to program one row or one word at a

time. Table 24-12 displays typical erase and program-

ming times. The 8-row erase pages and single row

write rows are edge-aligned, from the beginning of pro-

gram 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 set-

ting the control bits in the NVMCON register. A total of

64 TBLWTL and TBLWTH instructions are required to

load the instructions.

All of the table write operations are single-word writes

(two instruction cycles) because only the buffers are

written. A programming cycle is required for

programming each row.

5.3 Programming Operations

A complete programming sequence is necessary for

programming or erasing the internal Flash in RTSP

mode. The processor stalls (waits) until the

programming operation is finished.

The programming time depends on the FRC accuracy

(see Table 24-19) and the value of the FRC Oscillator

Tuning register (see Register 9-4). Use the following

formula to calculate the minimum and maximum values

for the Row Write Time, Page Erase Time and Word

Write Cycle Time parameters (see Table 24-12).

EQUATION 5-1: PROGRAMMING TIME

For example, if the device is operating at +125°C, the

FRC accuracy will be ±5%. If the TUN<5:0> bits (see

write time is equal to Equation 5-2.

EQUATION 5-2: MINIMUM ROW WRITE

TIME

The maximum row write time is equal to Equation 5-3.

EQUATION 5-3: MAXIMUM ROW WRITE

TIME

Setting the WR bit (NVMCON<15>) starts the

operation, and the WR bit is automatically cleared

when the operation is finished.

5.4 Control Registers

The two SFRs that are used to read and write the

program Flash memory are:

•NVMCON

• NVMKEY

The NVMCON register (Register 5-1) controls which

blocks are to be erased, which memory type is to be

programmed and the start of the programming cycle.

NVMKEY is a write-only register that is used for write

protection. To start a programming or erase sequence,

the user must consecutively write 0x55 and 0xAA to the

NVMKEY register. Refer to Section 5.3 “Programming

Operations” for further details.

5.4.1 PROGRAMMING ALGORITHM FOR

FLASH PROGRAM MEMORY

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. Read eight rows of program memory

(512 instructions) and store in data RAM.

2. Update the program data in RAM with the

desired new data.

3. Erase the page (see Example 5-1):

a) Set the NVMOP bits (NVMCON<3:0>) to

‘0010’ to configure for block erase. Set the

ERASE (NVMCON<6>) and WREN

(NVMCON<14>) bits.

b) Write the starting address of the page to be

erased into the TBLPAG and W registers.

c) Perform a dummy table write operation

(TBLWTL) to any address within the page

that needs to be erased.

d) Write 0x55 to NVMKEY.

e) Write 0xAA to NVMKEY.

f) Set the WR bit (NVMCON<15>). The erase

cycle begins and the CPU stalls for the dura-

tion of the erase cycle. When the erase is

done, the WR bit is cleared automatically.

4. Write the first 64 instructions from data RAM into

the program memory buffers (see Example 5-2).

5. 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 mem-

ory is done, the WR bit is cleared

automatically.

6. 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.

For protection against accidental operations, the write

initiate sequence for NVMKEY must be used to allow

any erase or program operation to proceed. After the

programming command has been executed, the user

must wait for the programming time until programming

is complete. The two instructions following the start of

the programming sequence should be NOPs, as shown

in Example 5-3.

Note: A program memory page erase operation

is set up by performing a dummy table

write (TBLWTL) operation to any address

within the page. This methodology is dif-

ferent 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).

6.0 RESET

The Reset module combines all Reset sources and

controls the device Master Reset Signal, SYSRST. The

following is a list of device Reset sources:

• POR: Power-on Reset

• BOR: Brown-out Reset

•MCLR

: Master Clear Pin Reset

•SWR: RESET Instruction

• WDT: Watchdog Timer Reset

• TRAPR: Trap Conflict Reset

• IOPUWR: Illegal Opcode and Uninitialized W

A simplified block diagram of the Reset module is

shown in Figure 6-1.

Any active source of Reset will make the SYSRST sig-

nal 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.

All types of device Reset will set a corresponding status

bit in the RCON register to indicate the type of Reset

(see Register 6-1). A POR will clear all bits, except for

the POR bit (RCON<0>), that are set. The user can set

or clear any bit at any time during code execution. The

RCON bits only serve as status bits. Setting a particular

Reset status bit in software does not cause a device

Reset to occur.

The RCON register also has other bits associated with

the Watchdog Timer and device power-saving states.

The function of these bits is discussed in other sections

of this manual.

TABLE 6-1: RESET FLAG BIT OPERATION

6.1 Clock Source Selection at Reset

If clock switching is enabled, the system clock source at

device Reset is chosen, as shown in Tab le 6 -2 . If clock

switching is disabled, the system clock source is always

selected according to the oscillator Configuration bits.

Refer to Section 9.0 “Oscillator Configuration” for

further details.

6.2 Device Reset Times

The Reset times for various types of device Reset are

summarized in Table 6-3. The system Reset signal is

released after the POR and PWRT delay times expire.

The time at which the device actually begins to execute

code also depends on the system oscillator delays,

which include the Oscillator Start-up Timer (OST) and

the PLL lock time. The OST and PLL lock times occur

in parallel with the applicable reset delay times.

The FSCM delay determines the time at which the

FSCM begins to monitor the system clock source after

the reset signal is released.

TABLE 6-3: RESET DELAY TIMES FOR VARIOUS DEVICE RESETS

6.2.1 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. There-

fore, the oscillator and PLL start-up delays must be

considered when the Reset delay time must be known.

6.2.2 FAIL-SAFE CLOCK MONITOR

(FSCM) AND DEVICE RESETS

If the FSCM is enabled, it begins to monitor the system

clock source when the Reset signal is released. If a

valid clock source is not available at this time, the

device automatically switches to the FRC oscillator and

the user can switch to the desired crystal oscillator in

the Trap Service Routine.

6.2.2.1 FSCM Delay for Crystal and PLL

Clock Sources

When the system clock source is provided by a crystal

oscillator and/or the PLL, a small delay, TFSCM, is auto-

matically inserted after the POR and PWRT delay

times. The FSCM does not begin to monitor the system

clock source until this delay expires. The FSCM delay

time is nominally 500 μs and provides additional time

for the oscillator and/or PLL to stabilize. In most cases,

the FSCM delay prevents an oscillator failure trap at a

device Reset when the PWRT is disabled.

6.3 Special Function Register Reset

States

Most of the Special Function Registers (SFRs) associ-

ated 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

7.0 INTERRUPT CONTROLLER

The PIC24HJXXXGPX06A/X08A/X10A interrupt con-

troller reduces the numerous peripheral interrupt

request signals to a single interrupt request signal to

the PIC24HJXXXGPX06A/X08A/X10A CPU. It has the

following features:

• Up to 8 processor exceptions and software traps

• 7 user-selectable priority levels

• Interrupt Vector Table (IVT) with up to 118 vectors

• A unique vector for each interrupt or exception

source

• Fixed priority within a specified user priority level

• Alternate Interrupt Vector Table (AIVT) for debug

support

• Fixed interrupt entry and return latencies

7.1 Interrupt Vector Table

The Interrupt Vector Table (IVT) is shown in Figure 7-1.

The IVT resides in program memory, starting at location

000004h. The IVT contains 126 vectors consisting of

8 nonmaskable trap vectors plus up to 118 sources of

interrupt. In general, each interrupt source has its own

vector. Each interrupt vector contains a 24-bit wide

address. The value programmed into each interrupt

vector location is the starting address of the associated

Interrupt Service Routine (ISR).

Interrupt vectors are prioritized in terms of their natural

priority; this priority is linked to their position in the

vector table. All other things being equal, lower

addresses have a higher natural priority. For example,

the interrupt associated with vector 0 will take priority

over interrupts at any other vector address.

PIC24HJXXXGPX06A/X08A/X10A devices implement

up to 61 unique interrupts and 5 nonmaskable traps.

These are summarized in Ta bl e 7 -1 and Ta b l e 7 - 2 .

7.1.1 ALTERNATE VECTOR TABLE

The Alternate Interrupt Vector Table (AIVT) is located

after the IVT, as shown in Figure 7-1. Access to the

AIVT is provided by the ALTIVT control bit

(INTCON2<15>). If the ALTIVT bit is set, all interrupt

and exception processes use the alternate vectors

instead of the default vectors. The alternate vectors are

organized in the same manner as the default vectors.

The AIVT supports debugging by providing a means to

switch between an application and a support environ-

ment without requiring the interrupt vectors to be

reprogrammed. This feature also enables switching

between applications for evaluation of different soft-

ware algorithms at run time. If the AIVT is not needed,

the AIVT should be programmed with the same

addresses used in the IVT.

7.2 Reset Sequence

A device Reset is not a true exception because the

interrupt controller is not involved in the Reset process.

The PIC24HJXXXGPX06A/X08A/X10A device clears

its registers in response to a Reset which forces the PC

to zero. The digital signal controller then begins pro-

gram execution at location 0x000000. The user pro-

grams a GOTO instruction at the Reset address which

redirects program execution to the appropriate start-up

routine.

and bit information.

locations in the IVT and AIVT should be

programmed with the address of a default

interrupt handler routine that contains a

RESET instruction.

7.3 Interrupt Control and Status

Registers

PIC24HJXXXGPX06A/X08A/X10A devices implement

a total of 30 registers for the interrupt controller:

• INTCON1

• INTCON2

• IFS0 through IFS4

• IEC0 through IEC4

• IPC0 through IPC17

•INTTREG

Global interrupt control functions are controlled from

INTCON1 and INTCON2. INTCON1 contains the Inter-

rupt 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 inter-

rupt vector number and the new CPU interrupt priority

level, which are latched into vector number (VEC-

NUM<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 Ta bl e 7- 1 . For example, the INT0 (External

Interrupt 0) is shown as having vector number 8 and a

natural order priority of 0. Thus, the INT0IF bit is found

in IFS0<0>, the INT0IE bit in IEC0<0>, and the INT0IP

bits in the first position of IPC0 (IPC0<2:0>).

Although they are not specifically part of the interrupt

control hardware, two of the CPU Control registers con-

tain 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 inter-

rupt priority level. The user can change the current

CPU priority level by writing to the IPL bits.

The CORCON register contains the IPL3 bit which,

together with IPL<2:0>, also indicates the current CPU

priority level. IPL3 is a read-only bit so that trap events

cannot be masked by the user software.

All Interrupt registers are described in Register 7-1

through Register 7-32.

7.4 Interrupt Setup Procedures

7.4.1 INITIALIZATION

To configure an interrupt source:

1. Set the NSTDIS bit (INTCON1<15>) if nested

interrupts are not desired.

2. 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.

3. Clear the interrupt flag status bit associated with

the peripheral in the associated IFSx register.

4. Enable the interrupt source by setting the inter-

rupt enable control bit associated with the

source in the appropriate IECx register.

7.4.2 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.

7.4.3 TRAP SERVICE ROUTINE

A Trap Service Routine (TSR) is coded like an ISR,

except that the appropriate trap status flag in the

INTCON1 register must be cleared to avoid re-entry

into the TSR.

7.4.4 INTERRUPT DISABLE

All user interrupts can be disabled using the following

procedure:

1. Push the current SR value onto the software

stack using the PUSH instruction.

2. 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 dis-

able interrupts of priority levels 1-6 for a fixed period of

time. Level 7 interrupt sources are not disabled by the

DISI instruction.

Note: At a device Reset, the IPCx registers are

initialized, such that all user interrupt

sources are assigned to priority level 4.

8.0 DIRECT MEMORY ACCESS

(DMA)

Direct Memory Access (DMA) is a very efficient

mechanism of copying data between peripheral SFRs

(e.g., UART Receive register, Input Capture 1 buffer),

and buffers or variables stored in RAM, with minimal

CPU intervention. The DMA controller can

automatically copy entire blocks of data without

requiring the user software to read or write the

peripheral Special Function Registers (SFRs) every

time a peripheral interrupt occurs. The DMA controller

uses a dedicated bus for data transfers and, therefore,

does not steal cycles from the code execution flow of

the CPU. To exploit the DMA capability, the

corresponding user buffers or variables must be

located in DMA RAM.

The PIC24HJXXXGPX06A/X08A/X10A peripherals

that can utilize DMA are listed in Ta b l e 8 - 1 along with

their associated Interrupt Request (IRQ) numbers.

TABLE 8-1: PERIPHERALS WITH DMA

SUPPORT

The DMA controller features eight identical data

transfer channels.

Each channel has its own set of control and status

registers. Each DMA channel can be configured to

copy data either from buffers stored in dual port DMA

RAM to peripheral SFRs, or from peripheral SFRs to

buffers in DMA RAM.

The DMA controller supports the following features:

• Word or byte sized data transfers

• Transfers from peripheral to DMA RAM or DMA

RAM to peripheral

• Indirect Addressing of DMA RAM locations with or

without automatic post-increment

• Peripheral Indirect Addressing – In some

peripherals, the DMA RAM read/write addresses

may be partially derived from the peripheral

• One-Shot Block Transfers – Terminating DMA

transfer after one block transfer

• Continuous Block Transfers – Reloading DMA RAM

buffer start address after every block transfer is

complete

• Ping-Pong Mode – Switching between two DMA

RAM start addresses between successive block

transfers, thereby filling two buffers alternately

• Automatic or manual initiation of block transfers

• Each channel can select from 19 possible sources

of data sources or destinations

For each DMA channel, a DMA interrupt request is

generated when a block transfer is complete. Alterna-

tively, an interrupt can be generated when half of the

block has been filled.

9.0 OSCILLATOR

CONFIGURATION

The PIC24HJXXXGPX06A/X08A/X10A oscillator

system provides:

• Various external and internal oscillator options as

clock sources

• 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

• An Oscillator Control register (OSCCON)

• Nonvolatile Configuration bits for main oscillator

selection.

A simplified diagram of the oscillator system is shown

in Figure 9-1.

9.1 CPU Clocking System

There are seven system clock options provided by the

PIC24HJXXXGPX06A/X08A/X10A:

• FRC Oscillator

• FRC Oscillator with PLL

• Primary (XT, HS or EC) Oscillator

• Primary Oscillator with PLL

• Secondary (LP) Oscillator

• LPRC Oscillator

• FRC Oscillator with postscaler

9.1.1 SYSTEM CLOCK SOURCES

The FRC (Fast RC) internal oscillator runs at a nominal

frequency of 7.37 MHz. The user software can tune the

FRC frequency. User software can optionally specify a

factor (ranging from 1:2 to 1:256) by which the FRC

clock frequency is divided. This factor is selected using

the FRCDIV<2:0> (CLKDIV<10:8>) bits.

The primary oscillator can use one of the following as

its clock source:

• XT (Crystal): Crystals and ceramic resonators in

the range of 3 MHz to 10 MHz. The crystal is con-

nected to the OSC1 and OSC2 pins.

• HS (High-Speed Crystal): Crystals in the range of

10 MHz to 40 MHz. The crystal is connected to

the OSC1 and OSC2 pins.

• EC (External Clock): External clock signal is

directly applied to the OSC1 pin.

The secondary (LP) oscillator is designed for low power

and uses a 32.768 kHz crystal or ceramic resonator.

The LP oscillator uses the SOSCI and SOSCO pins.

The LPRC (Low-Power RC) internal oscIllator runs at a

nominal frequency of 32.768 kHz. It is also used as a

reference clock by the Watchdog Timer (WDT) and

Fail-Safe Clock Monitor (FSCM).

The clock signals generated by the FRC and primary

oscillators can be optionally applied to an on-chip

Phase Locked Loop (PLL) to provide a wide range of

output frequencies for device operation. PLL

configuration is described in Section 9.1.3 “PLL

Configuration”.

The FRC frequency depends on the FRC accuracy

(see Table 24-19) and the value of the FRC Oscillator

Tuning register (see Register 9-4).

9.1.2 SYSTEM CLOCK SELECTION

The oscillator source that is used at a device Power-on

Reset event is selected using Configuration bit settings.

The oscillator Configuration bit settings are located in the

Configuration registers in the program memory. (Refer to

Section 21.1 “Configuration Bits” for further details.)

The Initial Oscillator Selection Configuration bits,

FNOSC<2:0> (FOSCSEL<2:0>), and the Primary Oscil-

lator Mode Select Configuration bits, POSCMD<1:0>

(FOSC<1:0>), select the oscillator source that is used at

a Power-on Reset. The FRC primary oscillator is the

default (unprogrammed) selection.

The Configuration bits allow users to choose between

twelve different clock modes, shown in Table 9-1.

The output of the oscillator (or the output of the PLL if

a PLL mode has been selected) FOSC is divided by 2 to

generate the device instruction clock (FCY) and the

peripheral clock time base (FP). FCY defines the

operating speed of the device, and speeds up to 40

MHz are supported by the PIC24HJXXXGPX06A/

X08A/X10A architecture.

Instruction execution speed or device operating

frequency, FCY, is calculated, as shown in

Equation 9-1:

EQUATION 9-1: DEVICE OPERATING

FREQUENCY

9.1.3 PLL CONFIGURATION

The primary oscillator and internal FRC oscillator can

optionally use an on-chip PLL to obtain higher speeds

of operation. The PLL provides a significant amount of

flexibility in selecting the device operating speed. A

block diagram of the PLL is shown in Figure 9-2.

The output of the primary oscillator or FRC, denoted as

‘FIN’, is divided down by a prescale factor (N1) of 2, 3,

... or 33 before being provided to the PLL’s Voltage

Controlled Oscillator (VCO). The input to the VCO must

be selected to be in the range of 0.8 MHz to 8 MHz.

Since the minimum prescale factor is 2, this implies that

FIN must be chosen to be in the range of 1.6 MHz to 16

MHz. The prescale factor ‘N1’ is selected using the

PLLPRE<4:0> bits (CLKDIV<4:0>).

The PLL Feedback Divisor, selected using the

PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor ‘M’,

by which the input to the VCO is multiplied. This factor

must be selected such that the resulting VCO output

frequency is in the range of 100 MHz to 200 MHz.

The VCO output is further divided by a postscale factor

‘N2’. This factor is selected using the PLLPOST<1:0>

bits (CLKDIV<7:6>). ‘N2’ can be either 2, 4 or 8, and

must be selected such that the PLL output frequency

(FOSC) is in the range of 12.5 MHz to 80 MHz, which

generates device operating speeds of 6.25-40 MIPS.

For a primary oscillator or FRC oscillator, output ‘FIN’,

the PLL output ‘FOSC’ is given by:

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.

PIC24HJXXXGPX06A/X08A/X10A

9.2 Clock Switching Operation

Applications are free to switch between any of the four

clock sources (Primary, LP, FRC and LPRC) under

software control at any time. To limit the possible side

effects that could result from this flexibility,

PIC24HJXXXGPX06A/X08A/X10A devices have a

safeguard lock built into the switch process.

9.2.1 ENABLING CLOCK SWITCHING

To enable clock switching, the FCKSM1 Configuration

bit in the Configuration register must be programmed to

‘0’. (Refer to Section 21.1 “Configuration Bits” for

further details.) If the FCKSM1 Configuration bit is

unprogrammed (‘1’), the clock switching function and

Fail-Safe Clock Monitor function are disabled. This is

the default setting.

The NOSC control bits (OSCCON<10:8>) do not

control the clock selection when clock switching is

disabled. However, the COSC bits (OSCCON<14:12>)

reflect the clock source selected by the FNOSC

Configuration bits.

The OSWEN control bit (OSCCON<0>) has no effect

when clock switching is disabled. It is held at ‘0’ at all

times.

9.2.2 OSCILLATOR SWITCHING SEQUENCE

At a minimum, performing a clock switch requires this

basic sequence:

1. If desired, read the COSC bits

(OSCCON<14:12>) to determine the current

oscillator source.

2. Perform the unlock sequence to allow a write to

the OSCCON register high byte.

3. Write the appropriate value to the NOSC control

bits (OSCCON<10:8>) for the new oscillator

source.

4. Perform the unlock sequence to allow a write to

the OSCCON register low byte.

5. Set the OSWEN bit to initiate the oscillator

switch.

Once the basic sequence is completed, the system

clock hardware responds automatically as follows:

1. The clock switching hardware compares the

COSC status bits with the new value of the

NOSC control bits. If they are the same, the

clock switch is a redundant operation. In this

case, the OSWEN bit is cleared automatically

and the clock switch is aborted.

2. If a valid clock switch has been initiated, the

LOCK (OSCCON<5>) and the CF

(OSCCON<3>) status bits are cleared.

3. 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).

4. The hardware waits for 10 clock cycles from the

new clock source and then performs the clock

switch.

5. 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.

6. 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).

9.3 Fail-Safe Clock Monitor (FSCM)

The Fail-Safe Clock Monitor (FSCM) allows the device

to continue to operate even in the event of an oscillator

failure. The FSCM function is enabled by programming.

If the FSCM function is enabled, the LPRC internal

oscillator runs at all times (except during Sleep mode)

and is not subject to control by the Watchdog Timer.

If an oscillator failure occurs, the FSCM generates a

clock failure trap event and switches the system clock

over to the FRC oscillator. Then the application

program can either attempt to restart the oscillator or

execute a controlled shutdown. The trap can be treated

as a warm Reset by simply loading the Reset address

into the oscillator fail trap vector.

If the PLL multiplier is used to scale the system clock,

the internal FRC is also multiplied by the same factor

on clock failure. Essentially, the device switches to

FRC with PLL on a clock failure.

Note: Primary Oscillator mode has three different

submodes (XT, HS and EC) which are

determined by the POSCMD<1:0> Config-

uration 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.

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 pri-

mary oscillator mode with PLL and

FRCPLL mode are not permitted. This

applies to clock switches in either direc-

tion. In these instances, the application

must switch to FRC mode as a transition

clock source between the two PLL modes.

(DS70227) in the “dsPIC33F/PIC24H

Family Reference Manual” for details.

PIC24HJXXXGPX06A/X08A/X10A

10.0 POWER-SAVING FEATURES

The PIC24HJXXXGPX06A/X08A/X10A devices

provide the ability to manage power consumption by

selectively managing clocking to the CPU and the

peripherals. In general, a lower clock frequency and a

reduction in the number of circuits being clocked

constitutes lower consumed power.

PIC24HJXXXGPX06A/X08A/X10A devices can

manage power consumption in four different ways:

• Clock frequency

• Instruction-based Sleep and Idle modes

• Software-controlled Doze mode

• Selective peripheral control in software

Combinations of these methods can be used to selec-

tively tailor an application’s power consumption while

still maintaining critical application features, such as

timing-sensitive communications.

10.1 Clock Frequency and Clock

Switching

PIC24HJXXXGPX06A/X08A/X10A devices allow a

wide range of clock frequencies to be selected under

application control. If the system clock configuration is

not locked, users can choose low-power or high-preci-

sion 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 pro-

cess, are discussed in more detail in Section 9.0

“Oscillator Configuration”.

10.2 Instruction-Based Power-Saving

Modes

PIC24HJXXXGPX06A/X08A/X10A devices have two

special power-saving modes that are entered through

the execution of a special PWRSAV instruction. Sleep

mode stops clock operation and halts all code execu-

tion. Idle mode halts the CPU and code execution, but

allows peripheral modules to continue operation. The

assembly syntax of the PWRSAV instruction is shown in

Example 10-1.

Sleep and Idle modes can be exited as a result of an

enabled interrupt, WDT time-out or a device Reset. When

the device exits these modes, it is said to “wake-up”.

10.2.1 SLEEP MODE

Sleep mode has these features:

• The system clock source is shut down. If an

on-chip oscillator is used, it is turned off.

• The device current consumption is reduced to a

minimum, provided that no I/O pin is sourcing

current

• The Fail-Safe Clock Monitor does not operate

during Sleep mode since the system clock source

is disabled

• The LPRC clock continues to run in Sleep mode if

the WDT is enabled

• The WDT, if enabled, is automatically cleared

prior to entering Sleep mode

• Some device features or peripherals may continue

to operate in Sleep mode. This includes items such

as the input change notification on the I/O ports, or

peripherals that use an external clock input. Any

peripheral that requires the system clock source for

its operation is disabled in Sleep mode.

The device will wake-up from Sleep mode on any of

these events:

• Any interrupt source that is individually enabled

• Any form of device Reset

• A WDT time-out

On wake-up from Sleep, the processor restarts with the

same clock source that was active when Sleep mode

was entered.

of the PIC24HJXXXGPX06A/X08A/X10A

family of devices. However, it is not

information in this data sheet, refer to

described in this section may not be

constants defined in the assembler

include file for the selected device.

PWRSAV #SLEEP_MODE ; Put the device into SLEEP mode

PWRSAV #IDLE_MODE ; Put the device into IDLE mode

PIC24HJXXXGPX06A/X08A/X10A

10.2.2 IDLE MODE

Idle mode has these features:

• The CPU stops executing instructions.

• The WDT is automatically cleared.

• The system clock source remains active. By

default, all peripheral modules continue to operate

normally from the system clock source, but can

also be selectively disabled (see Section 10.4

“Peripheral Module Disable”).

• If the WDT or FSCM is enabled, the LPRC also

remains active.

The device will wake from Idle mode on any of these

events:

• Any interrupt that is individually enabled.

• Any device Reset.

• A WDT time-out.

On wake-up from Idle, the clock is reapplied to the CPU

and instruction execution will begin (2-4 clock cycles

later), starting with the instruction following the PWRSAV

instruction, or the first instruction in the ISR.

10.2.3 INTERRUPTS COINCIDENT WITH

POWER SAVE INSTRUCTIONS

Any interrupt that coincides with the execution of a

PWRSAV instruction is held off until entry into Sleep or

Idle mode has completed. The device then wakes up

from Sleep or Idle mode.

10.3 Doze Mode

Generally, changing clock speed and invoking one of the

power-saving modes are the preferred strategies for

reducing power consumption. There may be cir-

cumstances, however, where this is not practical. For

example, it may be necessary for an application to main-

tain 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 contin-

ues 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.

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 applica-

tions. This allows clock-sensitive functions, such as

synchronous communications, to continue without

interruption while the CPU idles, waiting for something

to invoke an interrupt routine. Enabling the automatic

return to full-speed CPU operation on interrupts is

enabled by setting the ROI bit (CLKDIV<15>). By

default, interrupt events have no effect on Doze mode

operation.

For example, suppose the device is operating at

20 MIPS and the CAN module has been configured for

500 kbps based on this device operating speed. If the

device is now placed in Doze mode with a clock

frequency ratio of 1:4, the CAN module continues to

communicate at the required bit rate of 500 kbps, but

the CPU now starts executing instructions at a

frequency of 5 MIPS.

10.4 Peripheral Module Disable

The Peripheral Module Disable (PMD) registers

provide a method to disable a peripheral module by

stopping all clock sources supplied to that module.

When a peripheral is disabled via the appropriate PMD

control bit, the peripheral is in a minimum power

consumption state. The control and status registers

associated with the peripheral are also disabled, so

writes to those registers will have no effect and read

values will be invalid.

A peripheral module is only enabled if both the associ-

ated 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).

NOTES:

PIC24HJXXXGPX06A/X08A/X10A

11.0 I/O PORTS

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.

11.1 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 periph-

eral’s output buffer data and control signals are

provided to a pair of multiplexers. The multiplexers

select whether the peripheral or the associated port

has ownership of the output data and control signals of

the I/O pin. The logic also prevents “loop through”, in

which a port’s digital output can drive the input of a

peripheral that shares the same pin. Figure 11-1 shows

how ports are shared with other peripherals and the

associated I/O pin to which they are connected.

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

or an output. If the data direction bit is a ‘1’, the pin is

then an input. All port pins are defined as inputs after a

Reset. Reads from the latch (LATx), read the latch.

Writes to the latch, write the latch. Reads from the port

(PORTx), read the port pins, while writes to the port

pins, write the latch.

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 func-

tion that is defined as an input only, it is nonetheless

regarded as a dedicated port because there is no other

competing source of outputs. An example is the INT4

pin.

11.2 Open-Drain Configuration

In addition to the PORT, LAT and TRIS registers for

data control, some port pins can also be individually

configured for either digital or open-drain output. This is

controlled by the Open-Drain Control register, ODCx,

associated with each port. Setting any of the bits con-

figures the corresponding pin to act as an open-drain

output.

The open-drain feature allows the generation of

outputs higher than VDD (e.g., 5V) on any desired 5V

tolerant pins by using external pull-up resistors. The

maximum open-drain voltage allowed is the same as

the maximum VIH specification.

See the “Pin Diagrams” section for the available pins

and their functionality.

11.3 Configuring Analog Port Pins

The use of the ADxPCFGH, ADxPCFGL and TRIS

registers control the operation of the Analog-to-Digital

port pins. The port pins that are desired as analog

inputs must have their corresponding TRIS bit set

(input). If the TRIS bit is cleared (output), the digital out-

put level (VOH or VOL) is converted.

Clearing any bit in the ADxPCFGH or ADxPCFGL reg-

ister 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.

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.

11.4 I/O Port Write/Read Timing

One instruction cycle is required between a port

direction change or port write operation and a read

operation of the same port. Typically, this instruction

would be a NOP.

11.5 Input Change Notification

The input change notification function of the I/O ports

allows the PIC24HJXXXGPX06A/X08A/X10A devices

to generate interrupt requests to the processor in

response to a change-of-state on selected input pins.

This feature is capable of detecting input

change-of-states even in Sleep mode, when the clocks

are disabled. Depending on the device pin count, there

are up to 24 external signals (CN0 through CN23) that

can be selected (enabled) for generating an interrupt

request on a change-of-state.

There are four control registers associated with the CN

module. The CNEN1 and CNEN2 registers contain the

CN interrupt enable (CNxIE) control bits for each of the

CN input pins. Setting any of these bits enables a CN

interrupt for the corresponding pins.

Each CN pin also has a weak pull-up connected to it.

The pull-ups act as a current source that is connected

to the pin and eliminate the need for external resistors

when push button or keypad devices are connected.

The pull-ups are enabled separately using the CNPU1

and CNPU2 registers, which contain the weak pull-up

enable (CNxPUE) bits for each of the CN pins. Setting

any of the control bits enables the weak pull-ups for the

corresponding pins.

EXAMPLE 11-1: PORT WRITE/READ EXAMPLE

Note: In devices with two ADC modules, if the

corresponding PCFG bit in either

AD1PCFGH(L) and AD2PCFGH(L) is

cleared, the pin is configured as an analog

input.

Note: The voltage on an analog input pin can be

between -0.3V to (VDD + 0.3 V).

Note: Pull-ups on change notification pins

should always be disabled whenever the

port pin is configured as a digital output.

12.0 TIMER1

The Timer1 module is a 16-bit timer, which can serve

as the time counter for the real-time clock, or operate

as a free-running interval timer/counter. Timer1 can

operate in three modes:

• 16-bit Timer

• 16-bit Synchronous Counter

• 16-bit Asynchronous Counter

Timer1 also supports these features:

• Timer gate operation

• Selectable prescaler settings

• Timer operation during CPU Idle and Sleep

modes

• Interrupt on 16-bit Period register match or falling

edge of external gate signal

Figure 12-1 presents a block diagram of the 16-bit

timer module.

To configure Timer1 for operation:

1. Set the TON bit (= 1) in the T1CON register.

2. Select the timer prescaler ratio using the

TCKPS<1:0> bits in the T1CON register.

3. Set the Clock and Gating modes using the TCS

and TGATE bits in the T1CON register.

4. Set or clear the TSYNC bit in T1CON to select

synchronous or asynchronous operation.

5. Load the timer period value into the PR1

6. If interrupts are required, set the interrupt enable

bit, T1IE. Use the priority bits, T1IP<2:0>, to set

the interrupt priority.

13.0 TIMER2/3, TIMER4/5, TIMER6/7

AND TIMER8/9

The Timer2/3, Timer4/5, Timer6/7 and Timer8/9

modules are 32-bit timers, which can also be config-

ured as four independent 16-bit timers with selectable

operating modes.

As a 32-bit timer, Timer2/3, Timer4/5, Timer6/7 and

Timer8/9 operate in three modes:

• Two Independent 16-bit Timers (e.g., Timer2 and

Timer3) with all 16-bit operating modes (except

Asynchronous Counter mode)

• Single 32-bit Timer

• Single 32-bit Synchronous Counter

They also support these features:

• Timer Gate Operation

• Selectable Prescaler Settings

• Timer Operation during Idle and Sleep modes

• Interrupt on a 32-bit Period Register Match

• Time Base for Input Capture and Output Compare

Modules (Timer2 and Timer3 only)

• ADC1 Event Trigger (Timer2/3 only)

• ADC2 Event Trigger (Timer4/5 only)

Individually, all eight of the 16-bit timers can function as

synchronous timers or counters. They also offer the

features listed above, except for the event trigger; this

is implemented only with Timer2/3. The operating

modes and enabled features are determined by setting

the appropriate bit(s) in the T2CON, T3CON, T4CON,

T5CON, T6CON, T7CON, T8CON and T9CON regis-

ters. T2CON, T4CON, T6CON and T8CON are shown

in generic form in Register 13-1. T3CON, T5CON,

T7CON and T9CON are shown in Register 13-2.

For 32-bit timer/counter operation, Timer2, Timer4,

Timer6 or Timer8 is the least significant word; Timer3,

Timer5, Timer7 or Timer9 is the most significant word

of the 32-bit timers.

To configure Timer2/3, Timer4/5, Timer6/7 or Timer8/9

for 32-bit operation:

1. Set the corresponding T32 control bit.

2. Select the prescaler ratio for Timer2, Timer4,

Timer6 or Timer8 using the TCKPS<1:0> bits.

3. Set the Clock and Gating modes using the

corresponding TCS and TGATE bits.

4. 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.

5. 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.

6. 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. Clear the T32 bit corresponding to that timer.

2. Select the timer prescaler ratio using the

TCKPS<1:0> bits.

3. Set the Clock and Gating modes using the TCS

and TGATE bits.

4. Load the timer period value into the PRx

5. If interrupts are required, set the interrupt enable

bit, TxIE. Use the priority bits, TxIP<2:0>, to set

the interrupt priority.

6. Set the TON bit.

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 inter-

rupt is generated with the Timer3, Timer5,

Ttimer7 and Timer9 interrupt flags.

14.0 INPUT CAPTURE

The input capture module is useful in applications

requiring frequency (period) and pulse measurement.

The PIC24HJXXXGPX06A/X08A/X10A devices

support up to eight input capture channels.

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:

• Simple Capture Event modes:

- Capture timer value on every falling edge of

input at ICx pin

- Capture timer value on every rising edge of

input at ICx pin

• Capture timer value on every edge (rising and

falling)

• Prescaler Capture Event modes:

- Capture timer value on every 4th rising

edge of input at ICx pin

- Capture timer value on every 16th rising

edge of input at ICx pin

Each input capture channel can select 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.

15.0 OUTPUT COMPARE

The output compare module can select either Timer2 or

Timer3 for its time base. The module compares the

value of the timer with the value of one or two Compare

registers depending on the operating mode selected.

The state of the output pin changes when the timer

value matches the Compare register value. The output

compare module generates either a single output

pulse, or a sequence of output pulses, by changing the

state of the output pin on the compare match events.

The output compare module can also generate

interrupts on compare match events.

The output compare module has multiple operating

modes:

• Active-Low One-Shot mode

• Active-High One-Shot mode

• Toggle mode

• Delayed One-Shot mode

• Continuous Pulse mode

• PWM mode without Fault Protection

• PWM mode with Fault Protection

16.0 SERIAL PERIPHERAL

INTERFACE (SPI)

The Serial Peripheral Interface (SPI) module is a syn-

chronous serial interface useful for communicating with

other peripheral or microcontroller devices. These

peripheral devices may be serial EEPROMs, shift regis-

ters, display drivers, Analog-to-Digital converters, etc.

The SPI module is compatible with SPI and SIOP from

Motorola®.

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

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.

17.0 INTER-INTEGRATED

CIRCUIT™ (I2C™)

The Inter-Integrated Circuit (I2C) module provides

complete hardware support for both Slave and Multi-

Master modes of the I2C serial communication

standard, with a 16-bit interface.

The PIC24HJXXXGPX06A/X08A/X10A devices have

up to two I2C interface modules, denoted as I2C1 and

I2C2. Each I2C module has a 2-pin interface: the SCLx

pin is clock and the SDAx pin is data.

Each I2C module ‘x’ (x = 1 or 2) offers the following key

features:

•I

2C interface supporting both master and slave

operation

•I

2C Slave mode supports 7-bit and 10-bit

addressing

•I

2C Master mode supports 7-bit and 10-bit

addressing

•I

2C 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)

•I

2C supports multi-master operation; detects bus

collision and will arbitrate accordingly

17.1 Operating Modes

The hardware fully implements all the master and slave

functions of the I2C Standard and Fast mode

specifications, as well as 7 and 10-bit addressing.

The I2C module can operate either as a slave or a

master on an I2C bus.

The following types of I2C operation are supported:

•I

2C slave operation with 7-bit addressing

•I

2C slave operation with 10-bit addressing

•I

2C master operation with 7-bit or 10-bit addressing

For details about the communication sequence in each

of these modes, please refer to the “dsPIC33F/PIC24H

Family Reference Manual”.

17.2 I2C Registers

I2CxCON and I2CxSTAT are control and status

registers, respectively. The I2CxCON register is

readable and writable. The lower six bits of I2CxSTAT

are read-only. The remaining bits of the I2CSTAT are

read/write.

I2CxRSR is the shift register used for shifting data,

whereas I2CxRCV is the buffer register to which data

bytes are written, or from which data bytes are read.

I2CxRCV is the receive buffer. I2CxTRN is the transmit

operation.

The I2CxADD register holds the slave address. A

status bit, ADD10, indicates 10-bit Address mode. The

I2CxBRG acts as the Baud Rate Generator (BRG)

reload value.

In receive operations, I2CxRSR and I2CxRCV together

form a double-buffered receiver. When I2CxRSR

receives a complete byte, it is transferred to I2CxRCV

and an interrupt pulse is generated.

able in the PIC24HJXXXGPX06A/X08A/X10A device

family. The UART is a full-duplex asynchronous system

that can communicate with peripheral devices, such as

personal computers, LIN, RS-232 and RS-485 inter-

faces. The module also supports a hardware flow con-

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

• Hardware Flow Control Option with UxCTS and

UxRTS pins

• Fully Integrated Baud Rate Generator with 16-bit

Prescaler

• Baud rates ranging from 10 Mbps to 38 bps at 40

MIPS

• 4-deep First-In-First-Out (FIFO) Transmit Data

• 4-Deep FIFO Receive Data Buffer

• Parity, Framing and Buffer Overrun Error Detection

• Support for 9-bit mode with Address Detect

(9th bit = 1)

• Transmit and Receive Interrupts

• A Separate Interrupt for all UART Error Conditions

• Loopback mode for Diagnostic Support

• Support for Sync and Break Characters

• Supports Automatic Baud Rate Detection

•IrDA

® Encoder and Decoder Logic

• 16x Baud Clock Output for IrDA® Support

A simplified block diagram of the UART is shown in

Figure 18-1. The UART module consists of the key

important hardware elements:

• Baud Rate Generator

Note 1: This data sheet summarizes the features

of the PIC24HJXXXGPX06A/X08A/X10A

family of devices. However, it is not

intended to be a comprehensive refer-

ence source. To complement the infor-

mation in this data sheet, refer to Section

17. “UART” (DS70232) of the

“dsPIC33F/PIC24H Family Reference

Manual”, which is available from the

Microchip website (www.microchip.com).

2: Some registers and associated bits

described in this section may not be

available on all devices. Refer to

Section 4.0 “Memory Organization” in

this data sheet for device-specific register

and bit information.

Note 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).

PIC24HJXXXGPX06A/X08A/X10A

19.0 ENHANCED CAN (ECAN™)

MODULE

19.1 Overview

The Enhanced Controller Area Network (ECAN™)

module is a serial interface, useful for communicating

with other CAN modules or microcontroller devices.

This interface/protocol was designed to allow commu-

nications within noisy environments. The

PIC24HJXXXGPX06A/X08A/X10A devices contain up

to two ECAN modules.

The CAN module is a communication controller imple-

menting the CAN 2.0 A/B protocol, as defined in the

BOSCH specification. The module will support CAN 1.2,

CAN 2.0A, CAN 2.0B Passive and CAN 2.0B Active

versions of the protocol. The module implementation is

a full CAN system. The CAN specification is not covered

within this data sheet. The reader may refer to the

BOSCH CAN specification for further details.

The module features are as follows:

• Implementation of the CAN protocol, CAN 1.2,

CAN 2.0A and CAN 2.0B

• Standard and extended data frames

• 0-8 bytes data length

• Programmable bit rate up to 1 Mbit/sec

• Automatic response to remote transmission

requests

• Up to 8 transmit buffers with application specified

prioritization and abort capability (each buffer may

contain up to 8 bytes of data)

• Up to 32 receive buffers (each buffer may contain

up to 8 bytes of data)

• Up to 16 full (standard/extended identifier)

acceptance filters

• 3 full acceptance filter masks

• DeviceNet™ addressing support

• Programmable wake-up functionality with

integrated low-pass filter

• Programmable Loopback mode supports self-test

operation

• Signaling via interrupt capabilities for all CAN

receiver and transmitter error states

• Programmable clock source

• Programmable link to input capture module (IC2

for both CAN1 and CAN2) for time-stamping and

network synchronization

• Low-power Sleep and Idle mode

The CAN bus module consists of a protocol engine and

message buffering/control. The CAN protocol engine

handles all functions for receiving and transmitting

messages on the CAN bus. Messages are transmitted

by first loading the appropriate data registers. Status

and errors can be checked by reading the appropriate

registers. Any message detected on the CAN bus is

checked for errors and then matched against filters to

see if it should be received and stored in one of the

receive registers.

19.2 Frame Types

The CAN module transmits various types of frames

which include data messages, remote transmission

requests and as other frames that are automatically

generated for control purposes. The following frame

types are supported:

• Standard Data Frame:

A standard data frame is generated by a node when

the node wishes to transmit data. It includes an 11-bit

standard identifier (SID) but not an 18-bit extended

identifier (EID).

• Extended Data Frame:

An extended data frame is similar to a standard data

frame but includes an extended identifier as well.

• Remote Frame:

It is possible for a destination node to request the

data from the source. For this purpose, the

destination node sends a remote frame with an iden-

tifier 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 ille-

gal condition. Second, due to internal conditions, the

node is not yet able to start reception of the next

message. A node may generate a maximum of 2

sequential overload frames to delay the start of the

next message.

• Interframe Space:

Interframe space separates a proceeding frame (of

whatever type) from a following data or remote

frame.

19.3 Modes of Operation

The CAN module can operate in one of several operation

modes selected by the user. These modes include:

• Initialization Mode

• Disable Mode

• Normal Operation Mode

• Listen Only Mode

• Listen All Messages Mode

• Loopback Mode

Modes are requested by setting the REQOP<2:0> bits

(CiCTRL1<10:8>). Entry into a mode is Acknowledged

by monitoring the OPMODE<2:0> bits

(CiCTRL1<7:5>). The module will not change the mode

and the OPMODE bits until a change in mode is

acceptable, generally during bus Idle time, which is

defined as at least 11 consecutive recessive bits.

19.3.1 INITIALIZATION MODE

In the Initialization mode, the module will not transmit or

receive. The error counters are cleared and the inter-

rupt flags remain unchanged. The programmer will

have access to Configuration registers that are access

restricted in other modes. The module will protect the

user from accidentally violating the CAN protocol

through programming errors. All registers which control

the configuration of the module can not be modified

while the module is on-line. The CAN module will not

be allowed to enter the Configuration mode while a

transmission is taking place. The Configuration mode

serves as a lock to protect the following registers.

• All Module Control Registers

• Baud Rate and Interrupt Configuration Registers

• Bus Timing Registers

• Identifier Acceptance Filter Registers

• Identifier Acceptance Mask Registers

19.3.2 DISABLE MODE

In Disable mode, the module will not transmit or

receive. The module has the ability to set the WAKIF bit

due to bus activity, however, any pending interrupts will

remain and the error counters will retain their value.

If the REQOP<2:0> bits (CiCTRL1<10:8>) = 001, the

module will enter the Module Disable mode. If the module

is active, the module will wait for 11 recessive bits on the

CAN bus, detect that condition as an Idle bus, then

accept the module disable command. When the

OPMODE<2:0> bits (CiCTRL1<7:5>) = 001, that indi-

cates 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.

19.3.3 NORMAL OPERATION MODE

Normal Operation mode is selected when

REQOP<2:0> = 000. In this mode, the module is

activated and the I/O pins will assume the CAN bus

functions. The module will transmit and receive CAN

bus messages via the CiTX and CiRX pins.

19.3.4 LISTEN ONLY MODE

If the Listen Only mode is activated, the module on the

CAN bus is passive. The transmitter buffers revert to

the port I/O function. The receive pins remain inputs.

For the receiver, no error flags or Acknowledge signals

are sent. The error counters are deactivated in this

state. The Listen Only mode can be used for detecting

the baud rate on the CAN bus. To use this, it is neces-

sary that there are at least two further nodes that

communicate with each other.

19.3.5 LISTEN ALL MESSAGES MODE

The module can be set to ignore all errors and receive

any message. The Listen All Messages mode is acti-

vated 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 buf-

fer and can be read via the CPU interface.

19.3.6 LOOPBACK MODE

If the Loopback mode is activated, the module will con-

nect 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.

Note: Typically, if the CAN module is allowed to

transmit in a particular mode of operation

and a transmission is requested

immediately after the CAN module has

been placed in that mode of operation, the

module waits for 11 consecutive recessive

bits on the bus before starting

transmission. If the user application

switches to Disable mode within this 11-bit

period, the transmission is then aborted

and the corresponding TXABT bit is set

and the TXREQ bit is cleared.

20.0 10-BIT/12-BIT

ANALOG-TO-DIGITAL

CONVERTER (ADC)

The PIC24HJXXXGPX06A/X08A/X10A devices have

up to 32 Analog-to-Digital input channels. These

devices also have up to 2 Analog-to-Digital converter

modules (ADCx, where ‘x’ = 1 or 2), each with its own

set of Special Function Registers.

The AD12B bit (ADxCON1<10>) allows each of the

ADC modules to be configured by the user as either a

10-bit, 4-sample/hold ADC (default configuration) or a

12-bit, 1-sample/hold ADC.

20.1 Key Features

The 10-bit ADC configuration has the following key

features:

• Successive Approximation (SAR) conversion

• Conversion speeds of up to 1.1 Msps

• Up to 32 analog input pins

• External voltage reference input pins

• Simultaneous sampling of up to four analog input

pins

• Automatic Channel Scan mode

• Selectable conversion trigger source

• Selectable Buffer Fill modes

• Two result alignment options (signed/unsigned)

• Operation during CPU Sleep and Idle modes

The 12-bit ADC configuration supports all the above

features, except:

• In the 12-bit configuration, conversion speeds of

up to 500 ksps are supported

• There is only 1 sample/hold amplifier in the 12-bit

configuration, so simultaneous sampling of

multiple channels is not supported.

Depending on the particular device pinout, the Ana-

log-to-Digital Converter can have up to 32 analog input

pins, designated AN0 through AN31. In addition, there

are two analog input pins for external voltage reference

connections. These voltage reference inputs may be

shared with other analog input pins. The actual number

of analog input pins and external voltage reference

input configuration will depend on the specific device.

Refer to the device data sheet for further details.

A block diagram of the Analog-to-Digital Converter is

shown in Figure 20-1.

20.2 Analog-to-Digital Initialization

The following configuration steps should be performed.

1. Configure the ADC module:

a) Select port pins as analog inputs

(ADxPCFGH<15:0> or ADxPCFGL<15:0>)

b) Select voltage reference source to match

expected range on analog inputs

(ADxCON2<15:13>)

c) Select the analog conversion clock to

match desired data rate with processor

clock (ADxCON3<7:0>)

d) Determine how many S/H channels will

be used (ADxCON2<9:8> and

ADxPCFGH<15:0> or ADxPCFGL<15:0>)

e) Select the appropriate sample/conversion

sequence (ADxCON1<7:5> and

ADxCON3<12:8>)

f) Select how conversion results are

presented in the buffer (ADxCON1<9:8>)

g) Turn on the ADC module (ADxCON1<15>)

2. Configure ADC interrupt (if required):

a) Clear the ADxIF bit

b) Select ADC interrupt priority

20.3 ADC and DMA

If more than one conversion result needs to be buffered

before triggering an interrupt, DMA data transfers can

be used. Both ADC1 and ADC2 can trigger a DMA data

transfer. If ADC1 or ADC2 is selected as the DMA IRQ

source, a DMA transfer occurs when the AD1IF or

AD2IF bit gets set as a result of an ADC1 or ADC2

sample conversion sequence.

The SMPI<3:0> bits (ADxCON2<5:2>) are used to

select how often the DMA RAM buffer pointer is

incremented.

The ADDMABM bit (ADxCON1<12>) determines how

the conversion results are filled in the DMA RAM buffer

area being used for ADC. If this bit is set, DMA buffers

are written in the order of conversion. The module will

provide an address to the DMA channel that is the

same as the address used for the non-DMA

stand-alone buffer. If the ADDMABM bit is cleared, the

DMA buffers are written in Scatter/Gather mode. The

module will provide a scatter/gather address to the

DMA channel, based on the index of the analog input

and the size of the DMA buffer.

Note 1: This data sheet summarizes the features

of the PIC24HJXXXGPX06A/X08A/X10A

family of devices. However, it is not

intended to be a comprehensive refer-

ence source. To complement the infor-

mation in this data sheet, refer to the

“dsPIC33F/PIC24H Family Reference

Manual”, Section 16. “Analog-to-Digital

Converter (ADC)” (DS70225), which is

available from the Microchip website

(www.microchip.com).

2: Some registers and associated bits

described in this section may not be

available on all devices. Refer to

Section 4.0 “Memory Organization” in

this data sheet for device-specific register

and bit information.

Note: The ADC module needs to be disabled

before modifying the AD12B bit.

21.1 Configuration Bits

PIC24HJXXXGPX06A/X08A/X10A devices provide

nonvolatile memory implementation for device

configuration bits. Refer to Section 25. “Device Con-

figuration” (DS70194) of the “dsPIC33F/PIC24H

Family Reference Manual”, for more information on this

implementation.

The Configuration bits can be programmed (read as

‘0’), or left unprogrammed (read as ‘1’), to select vari-

ous device configurations. These bits are mapped

starting at program memory location 0xF80000.

The device Configuration register map is shown in

Table 21-1.

The individual Configuration bit descriptions for the

Configuration registers are shown in Table 21-2.

Note that address 0xF80000 is beyond the user program

21.2 On-Chip Voltage Regulator

All of the PIC24HJXXXGPX06A/X08A/X10A 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

PIC24HJXXXGPX06A/X08A/X10A family incorporate

an on-chip regulator that allows the device to run its

core logic from VDD.

The regulator provides power to the core from the other

VDD pins. The regulator requires that a low-ESR (less

than 5 ohms) capacitor (such as tantalum or ceramic)

be connected to the VCAP pin (Figure 21-1). This helps

to maintain the stability of the regulator. The

recommended value for the filter capacitor is provided

in Table 24-13 of Section 24.1 “DC Characteristics”.

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.

REGULATOR(1)

CONNECTIONS

21.3 Brown-out Reset (BOR)

The BOR (Brown-out Reset) module is based on an

internal voltage reference circuit that monitors the reg-

ulated voltage VCAP. The main purpose of the BOR

module is to generate a device Reset when a

brown-out condition occurs. Brown-out conditions are

generally caused by glitches on the AC mains (i.e.,

missing portions of the AC cycle waveform due to bad

power transmission lines or voltage sags due to exces-

sive current draw when a large inductive load is turned

on).

A BOR will generate a Reset pulse which will reset the

device. The BOR will select the clock source, based on

the device Configuration bit values (FNOSC<2:0> and

POSCMD<1:0>). Furthermore, if an oscillator mode is

selected, the BOR will activate the Oscillator Start-up

Timer (OST). The system clock is held until OST

expires. If the PLL is used, the clock will be held until

the LOCK bit (OSCCON<5>) is ‘1’.

Concurrently, the PWRT time-out (TPWRT) will be

applied before the internal Reset is released. If

TPWRT = 0 and a crystal oscillator is being used, a

nominal delay of TFSCM = 100 is applied. The total

delay in this case is TFSCM.

The BOR Status bit (RCON<1>) will be set to indicate

that a BOR has occurred. The BOR circuit continues to

operate while in Sleep or Idle modes and will reset the

device should VDD fall below the BOR threshold

voltage.

Note: It is important for the low-ESR capacitor to

be placed as close as possible to the VCAP

pin.

21.4 Watchdog Timer (WDT)

For PIC24HJXXXGPX06A/X08A/X10A devices, the

WDT is driven by the LPRC oscillator. When the WDT

is enabled, the clock source is also enabled.

The nominal WDT clock source from LPRC is 32 kHz.

This feeds a prescaler than can be configured for either

5-bit (divide-by-32) or 7-bit (divide-by-128) operation.

The prescaler is set by the WDTPRE Configuration bit.

With a 32 kHz input, the prescaler yields a nominal

WDT time-out period (TWDT) of 1 ms in 5-bit mode, or

4 ms in 7-bit mode.

A variable postscaler divides down the WDT prescaler

output and allows for a wide range of time-out periods.

The postscaler is controlled by the WDTPOST<3:0>

Configuration bits (FWDT<3:0>) which allow the selec-

tion 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

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 exe-

cuted. 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.

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 con-

trol bit is cleared on any device Reset. The software

WDT option allows the user to enable the WDT for crit-

ical code segments and disable the WDT during

non-critical segments for maximum power savings.

FIGURE 21-2: WDT BLOCK DIAGRAM

Note: The CLRWDT and PWRSAV instructions

clear the prescaler and postscaler counts

when executed.

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.

21.5 JTAG Interface

PIC24HJXXXGPX06A/X08A/X10A devices implement

a JTAG interface, which supports boundary scan

device testing, as well as in-circuit programming.

Detailed information on the interface will be provided in

future revisions of the document.

21.6 Code Protection and

CodeGuard™ Security

The PIC24H product families offer advanced imple-

mentation of CodeGuard™ Security. CodeGuard

Security enables multiple parties to securely share

resources (memory, interrupts and peripherals) on a

single chip. This feature helps protect individual

Intellectual Property in collaborative system designs.

When coupled with software encryption libraries,

CodeGuard Security can be used to securely update

Flash even when multiple IP are resident on the single

chip. The code protection features vary depending on

the actual PIC24H implemented. The following

sections provide an overview these features.

The code protection features are controlled by the

Configuration registers: FBS, FSS and FGS.

21.7 In-Circuit Serial Programming

Programming Capability

PIC24HJXXXGPX06A/X08A/X10A family digital signal

controllers can be serially programmed while in the end

application circuit. This is simply done with two lines for

clock and data and three other lines for power, ground

and the programming sequence. This allows custom-

ers 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 pro-

grammed. Please refer to the “dsPIC33F/PIC24H

Flash Programming Specification” (DS70152)

document for details about ICSP programming

capability.

Any one out of three pairs of programming clock/data

pins may be used:

• PGEC1 and PGED1

• PGEC2 and PGED2

• PGEC3 and PGED3

21.8 In-Circuit Debugger

When MPLAB® ICD 2 is selected as a debugger, the

in-circuit debugging functionality is enabled. This func-

tion allows simple debugging functions when used with

MPLAB IDE. Debugging functionality is controlled

through the PGECx (Emulation/Debug Clock) and

PGEDx (Emulation/Debug Data) pin functions.

Any one out of three pairs of debugging clock/data pins

may be used:

• PGEC1 and PGED1

• PGEC2 and PGED2

• PGEC3 and PGED3

To use the in-circuit debugger function of the device,

the design must implement ICSP programming capa-

bility connections to MCLR, VDD, VSS and the PGEDx/

PGECx pin pair. In addition, when the feature is

enabled, some of the resources are not available for

general use. These resources include the first 80 bytes

of data RAM and two I/O pins.

PIC24HJXXXGPX06A/X08A/X10A

22.0 INSTRUCTION SET SUMMARY

The PIC24H instruction set is identical to that of the

PIC24F, and is a subset of the dsPIC30F/33F

instruction set.

Most instructions are a single program memory word

(24 bits). Only three instructions require two program

memory locations.

Each single-word instruction is a 24-bit word, divided

into an 8-bit opcode, which specifies the instruction

type and one or more operands, which further specify

the operation of the instruction.

The instruction set is highly orthogonal and is grouped

into five basic categories:

• Word or byte-oriented operations

• Bit-oriented operations

• Literal operations

• DSP operations

• Control operations

Table 22-1 shows the general symbols used in

describing the instructions.

The PIC24H instruction set summary in Ta b le 2 2 -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

• The second source operand which is typically a

• The destination of the result which is typically a

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

‘WREG’

Most bit-oriented instructions (including simple

rotate/shift instructions) have two operands:

• The W register (with or without an address

modifier) or file register (specified by the value of

‘Ws’ or ‘f’)

• The bit in the W register or file register

(specified by a literal value or indirectly by the

contents of register ‘Wb’)

The literal instructions that involve data movement may

use some of the following operands:

• A literal value to be loaded into a W register or file

• 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

The control instructions may use some of the following

operands:

• A program memory address

• The mode of the table read and table write

instructions

All instructions are a single word, except for certain

double word instructions, which were made double

word instructions so that all the required information is

available in these 48 bits. In the second word, the

8 MSbs are ‘0’s. If this second word is executed as an

instruction (by itself), it will execute as a NOP.

Most single-word instructions are executed in a single

instruction cycle, unless a conditional test is true, or the

program counter is changed as a result of the instruc-

tion. In these cases, the execution takes two instruction

cycles with the additional instruction cycle(s) executed

as a NOP. Notable exceptions are the BRA (uncondi-

tional/computed branch), indirect CALL/GOTO, all table

reads and writes and RETURN/RETFIE instructions,

which are single-word instructions but take two or three

cycles. Certain instructions that involve skipping over the

subsequent instruction require either two or three cycles

if the skip is performed, depending on whether the

instruction being skipped is a single-word or double word

instruction. Moreover, double word moves require two

cycles. The double word instructions execute in two

instruction cycles.

dsPIC30 and dsPIC33 families of digital signal control-

lers. These compilers provide powerful integration

capabilities, superior code optimization and ease of

use.

For easy source level debugging, the compilers provide

symbol information that is optimized to the MPLAB IDE

debugger.

23.3 HI-TECH C for Various Device

Families

The HI-TECH C Compiler code development systems

are complete ANSI C compilers for Microchip’s PIC

family of microcontrollers and the dsPIC family of digital

signal controllers. These compilers provide powerful

integration capabilities, omniscient code generation

and ease of use.

symbol information that is optimized to the MPLAB IDE

debugger.

The compilers include a macro assembler, linker, pre-

processor, and one-step driver, and can run on multiple

platforms.

23.4 MPASM Assembler

The MPASM Assembler is a full-featured, universal

macro assembler for PIC10/12/16/18 MCUs.

The MPASM Assembler generates relocatable object

files for the MPLINK Object Linker, Intel® standard HEX

files, MAP files to detail memory usage and symbol

reference, absolute LST files that contain source lines

and generated machine code and COFF files for

debugging.

The MPASM Assembler features include:

• Integration into MPLAB IDE projects

• User-defined macros to streamline

assembly code

objects created by the MPASM Assembler and the

MPLAB C18 C Compiler. It can link relocatable objects

from precompiled libraries, using directives from a

linker script.

The MPLIB Object Librarian manages the creation and

modification of library files of precompiled code. When

a routine from a library is called from a source file, only

the modules that contain that routine will be linked in

with the application. This allows large libraries to be

used efficiently in many different applications.

The object linker/library features include:

• Efficient linking of single libraries instead of many

smaller files

• Enhanced code maintainability by grouping

related modules together

• Flexible creation of libraries with easy module

listing, replacement, deletion and extraction

MPLAB Assembler produces relocatable machine

code from symbolic assembly language for PIC24,

PIC32 and dsPIC devices. MPLAB C Compiler uses

the assembler to produce its object file. The assembler

generates relocatable object files that can then be

archived or linked with other relocatable object files and

archives to create an executable file. Notable features

of the assembler include:

• Support for the entire device instruction set

• Support for fixed-point and floating-point data

• Command line interface

• Rich directive set

• Flexible macro language

• MPLAB IDE compatibility

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 C Compilers,

and the MPASM and MPLAB Assemblers. The soft-

ware simulator offers the flexibility to develop and

debug code outside of the hardware laboratory envi-

ronment, making it an excellent, economical software

development tool.

2: 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.

3: Measurements are taken in EC mode. The CLKO signal is measured on the OSC2 pin.

2: These parameters are characterized by similarity but are not tested in manufacturing. This specification is

based on clock cycle by clock cycle measurements. To calculate the effective jitter for individual time base

or communication clocks used by peripherals use the formula:

Peripheral Clock Jitter = DCLK / √(FOSC/Peripheral bit rate clock)

Example Only: Fosc = 80 MHz, DCLK = 3%, SPI bit rate clock, (i.e. SCK), is 5 MHz

SPI SCK Jitter = [ DCLK / √(80 MHz/5 MHz)] = [3%/ √16] = [3% / 4] = 0.75%

25.0 HIGH TEMPERATURE ELECTRICAL CHARACTERISTICS

This section provides an overview of PIC24HJXXXGPX06A/X08A/X10A electrical characteristics for devices operating

in an ambient temperature range of -40°C to +150°C.

The specifications between -40°C to +150°C are identical to those shown in Section 24.0 “Electrical Characteristics”

for operation between -40°C to +125°C, with the exception of the parameters listed in this section.

Parameters in this section begin with an H, which denotes High temperature. For example, parameter DC10 in

Section 24.0 “Electrical Characteristics” is the Industrial and Extended temperature equivalent of HDC10.

Absolute maximum ratings for the PIC24HJXXXGPX06A/X08A/X10A high temperature devices are listed below.

Exposure to these maximum rating conditions for extended periods can affect device reliability. Functional operation of

the device at these or any other conditions above the parameters indicated in the operation listings of this specification

is not implied.

Absolute Maximum Ratings(1)

Ambient temperature under bias(4) .........................................................................................................-40°C to +150°C

Storage temperature .............................................................................................................................. -65°C to +160°C

Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +4.0V

Voltage on any pin that is not 5V tolerant with respect to VSS(5) .................................................... -0.3V to (VDD + 0.3V)

Voltage on any 5V tolerant pin with respect to VSS when VDD < 3.0V(5) ....................................... -0.3V to (VDD + 0.3V)

Voltage on any 5V tolerant pin with respect to VSS when VDD ≥ 3.0V(5) .................................................... -0.3V to 5.6V

Voltage on VCAP with respect to VSS ...................................................................................................... 2.25V to 2.75V

Maximum current out of VSS pin .............................................................................................................................60 mA

Maximum current into VDD pin(2).............................................................................................................................60 mA

Maximum junction temperature............................................................................................................................. +155°C

Maximum output current sunk by any I/O pin(3) ........................................................................................................1 mA

Maximum output current sourced by any I/O pin(3)...................................................................................................1 mA

Maximum current sunk by all ports combined ........................................................................................................10 mA

Maximum current sourced by all ports combined(2) ................................................................................................10 mA

Note: Programming of the Flash memory is not allowed above 125°C.

Note 1: Stresses above those listed under “Absolute Maximum Ratings” can cause permanent damage to the

device. This is a stress rating only, and functional operation of the device at those or any other conditions

above those indicated in the operation listings of this specification is not implied. Exposure to maximum

rating conditions for extended periods can affect device reliability.

2: Maximum allowable current is a function of device maximum power dissipation (see Table 25-2).

3: Unlike devices at 125°C and below, the specifications in this section also apply to the CLKOUT, VREF+,

VREF-, SCLx, SDAx, PGECx, and PGEDx pins.

4: AEC-Q100 reliability testing for devices intended to operate at 150°C is 1,000 hours. Any design in which

the total operating time from 125°C to 150°C will be greater than 1,000 hours is not warranted without prior

written approval from Microchip Technology Inc.

5: Refer to the “Pin Diagrams” section for 5V tolerant pins.

NOTES:

PIC24HJXXXGPX06A/X08A/X10A

APPENDIX A: MIGRATING FROM

PIC24HJXXXGPX06/

X08/X10 DEVICES TO

PIC24HJXXXGPX06A/

X08A/X10A DEVICES

PIC24HJXXXGPX06A/X08A/X10A devices were

designed to enhance the PIC24HJXXXGPX06/X08/

X10 families of devices.

In general, the PIC24HJXXXGPX06A/X08A/X10A

devices are backward-compatible with

PIC24HJXXXGPX06/X08/X10 devices; however, man-

ufacturing differences may cause

PIC24HJXXXGPX06A/X08A/X10A devices to behave

differently from PIC24HJXXXGPX06/X08/X10 devices.

Therefore, complete system test and characterization

is recommended if PIC24HJXXXGPX06A/X08A/X10A

devices are used to replace PIC24HJXXXGPX06/X08/

X10 devices.

The following enhancements were introduced:

• Extended temperature support of up to +125ºC

• Enhanced Flash module with higher endurance

and retention

• New PLL Lock Enable configuration bit

• Added Timer5 trigger for ADC1 and Timer3

trigger for ADC2
