PIC24HJ32GP202/204 and PIC24HJ16GP304 family
microcontrollers can be serially programmed while in
the end application circuit. This is done with two lines
for clock and data, and three other lines for power,
ground and the programming sequence. Serial pro-
gramming allows customers to manufacture boards
with unprogrammed devices and then program the
microcontroller just before shipping the product. Serial
programming also allows the most recent firmware or a
custom firmware to be programmed. Refer to the
“dsPIC30F/33F Flash Programming Specification”
(DS70152) document for details about In-Circuit Serial
Programming (ICSP).
Any of the following three pairs of programming clock/
data pins can be used:
• PGC1/EMUC1 and PGD1/EMUD1
• PGC2/EMUC2 and PGD2/EMUD2
• PGC3/EMUC3 and PGD3/EMUD3

Preliminary

When MPLAB
circuit debugging functionality is enabled. This function
allows simple debugging functions when used with
MPLAB IDE. Debugging functionality is controlled
through the
Emulation/Debug Data (EMUDx) pin functions.
Any of the following three pairs of debugging clock/data
pins can be used:
• PGC1/EMUC1 and PGD1/EMUD1
• PGC2/EMUC2 and PGD2/EMUD2
• PGC3/EMUC3 and PGD3/EMUD3
To make use of the in-circuit debugger function of the
device, the design must implement ICSP connections
to MCLR, V
EMUCx pin pair. In addition, when the feature is
enabled, some of the resources are not available for
general use. These resources include the first 80 bytes
of data RAM and two I/O pins.
