The
(Enhanced ICSP) protocol uses a faster method that
takes advantage of the programming executive, as
illustrated in
provides all the necessary functionality to erase, pro-
gram and verify the chip through a small command set.
The command set allows the programmer to program
the PIC24FJXXXDA1/DA2/GB2/GA3 MCUs without
having to deal with the low-level programming
protocols of the chip.
FIGURE 2-1:
This specification is divided into major sections that
describe the programming methods independently.
Section 3.0 “Device Programming – ICSP”
the In-Circuit Serial Programming method.
“Device Programming – Enhanced ICSP”
the Run-Time Self-Programming (RTSP) method.
2.1
All PIC24FJXXXDA1/DA2/GB2/GA3 devices power
their core digital logic at a nominal 1.8V. To simplify sys-
tem design, all devices in the PIC24FJXXXDA1/DA2/
GB2/GA3 families incorporate an on-chip regulator that
allows the device to run its core logic from V
PIC24F128GA310 family, the regulator is always
enabled, so there is no ENVREG pin on the device.
The regulator provides power to the core from the other

The Flash program memory on PIC24FJXXXDA1/DA2/
GB2/GA3 devices has a specific write/erase require-
ment that must be adhered to for proper device
is located. Thus, the easiest way to conform to this rule
is to write all of the data in a programming block within
one write cycle. The programming methods specified in
this specification comply with this requirement.

2.3.1
All of the devices in the PIC24FJXXXDA1/DA2/GB2/
GA3 families have three separate pairs of program-
ming pins, labelled as PGEC1/PGED1, PGEC2/PGED2
and PGEC3/PGED3. Any one of these pin pairs may be
used for device programming by either ICSP or
Enhanced ICSP. Unlike voltage supply and ground
pins, it is not necessary to connect all three pin pairs to
program the device. However, the programming
method must use both pins of the same pair.
