1.0 DEVICE OVERVIEW

This document defines the programming specification

for the PIC24FJXXXDA1/DA2/GB2/GA3/GC0 families

of 16-bit microcontrollers (MCUs). This programming

specification is required only for those developing pro-

gramming support for the PIC24FJXXXDA1/DA2/GB2/

GA3/GC0 families. Customers using only one of these

devices should use development tools that already

provide support for device programming.

This specification includes programming specifications

for the following devices:

2.0 PROGRAMMING OVERVIEW

OF THE PIC24FJXXXDA1/DA2/

GB2/GA3/GC0 FAMILIES

There are two methods of programming the

PIC24FJXXXDA1/DA2/GB2/GA3/GC0 families of

devices discussed in this programming specification.

They are:

• In-Circuit Serial Programming™ (ICSP™)

• Enhanced In-Circuit Serial Programming

(Enhanced ICSP)

The ICSP programming method is the most direct

method to program the device; however, it is also the

slower of the two methods. It provides native, low-level

programming capability to erase, program and verify

the chip.

The Enhanced In-Circuit Serial Programming

(Enhanced ICSP) protocol uses a faster method that

takes advantage of the Programming Executive (PE),

as illustrated in Figure 2-1. The Programming Execu-

tive provides all the necessary functionality to erase,

program and verify the chip through a small command

set. The command set allows the programmer to

program the PIC24FJXXXDA1/DA2/GB2/GA3/GC0

MCUs without having to deal with the low-level

programming protocols of the chip.

FIGURE 2-1: PROGRAMMING SYSTEM

OVERVIEW FOR

ENHANCED ICSP™

This specification is divided into major sections that

describe the programming methods independently.

Section 3.0 “Device Programming – ICSP” describes

the In-Circuit Serial Programming method. Section 4.0

“Device Programming – Enhanced ICSP” describes

the Run-Time Self-Programming (RTSP) method.

Note: The address of Special Function Register,

TBLPAG, has changed from 0x32 to 0x54

in PIC24FJXXXDA1/DA2/GB2/GA3/GC0

family devices.

In those cases where legacy programming

specification code from other device

families is used as a basis to implement

the PIC24FJXXXDA1/DA2/GB2/GA3/GC0

families’ programming specification, spe-

cial care must be taken to ensure all

references to TBLPAG, in any existing

code, are updated with the correct opcode

hex data for the mnemonic and operands

(as shown below).
