PIC24FJ64GA004 family microcontrollers can be seri-
ally programmed while in the end application circuit.
This is simply done with two lines for clock (PGCx) and
data (PGDx) and three other lines for power, ground
and the programming voltage. This allows customers to
manufacture boards with unprogrammed devices and
then program the microcontroller just before shipping
the product. This also allows the most recent firmware
or a custom firmware to be programmed.

Preliminary
23.7
When MPLAB
in-circuit debugging functionality is enabled. This func-
tion allows simple debugging functions when used with
MPLAB IDE. Debugging functionality is controlled
through the EMUCx (Emulation/Debug Clock) and
EMUDx (Emulation/Debug Data) pins.
To use the in-circuit debugger function of the device,
the design must implement ICSP connections to
MCLR,
EMUDx/EMUCx pin pair. In addition, when the feature
is enabled, some of the resources are not available for
general use. These resources include the first 80 bytes
of data RAM and two I/O pins.
