dsPIC33F DEVICES WITH VOLATILE CONFIGURATION BITS
3.0
ICSP mode is a special programming protocol that
allows you to read and write to dsPIC33F device family
memory. The ICSP mode is the most direct method
used to program the device, which is accomplished by
applying control codes and instructions serially to the
device using the PGECx and PGEDx pins. ICSP mode
also has the ability to read executive memory to deter-
mine if the programming executive is present and to
write the programming executive to executive memory
if Enhanced ICSP (E-ICSP) mode will be used.
In ICSP mode, the system clock is taken from the
PGECx pin, regardless of the device’s oscillator Con-
figuration bits. All instructions are shifted serially into an
internal buffer, then loaded into the instruction register
and executed. No program fetching occurs from inter-
nal memory. Instructions are fed in 24 bits at a time.
PGEDx is used to shift data in, and PGECx is used as
both the serial shift clock and the CPU execution clock.

programming process. After entering ICSP mode, the
first action is to Bulk Erase program memory. Next, the
code memory is programmed, followed by the device
Configuration words. Code memory (including the
Configuration words) is then verified to ensure that pro-
gramming was successful. Then, program the
code-protect Configuration bits, if required.
