ICSP connection

Support summary

  • Programming - Yes
  • Debugging provisions - Yes

ICSP Connection

dsPIC33CDV64MC106 has more than one pair of PGECx and PGEDx pins. You can use any pair, but you must use them as a pair. For example, if PGEC2 is used for ICSPCLK, then ICSPDAT must be connected to PGED2.

All VSS and VDD pins must be connected. Even if one of these pins is not connected, programming may fail.

ICSP write inhibition

It is possible to configure dsPIC33CDV64MC106 to inhibit all future ICSP writes. Once this is done, the PIC can never be re-programmed again. It is possible to read the chip with nsread if it is not read-protected.

To inhibit all future ICSP writes, use the following command:

nsprog inhibit-ICSP-write-irreversibly -d dsPIC33CDV64MC106

This action is irreversible. Once you inhibit the ICSP writes, dsPIC33CDV64MC106 cannot be re-programmed.


NSDSP firmware contains all the necessary provisions for debugging dsPIC33CDV64MC106 and may be debugged when debugging software becomes available.

dsPIC33CDV64MC106 uses unordered halting, has 8 hardware breakpoints.

Debugging does not consume resources in the user space.
