dsPIC33CK256MC103

Support summary

• Programming - Yes
• Debugging provisions - Yes

ICSP Connection

dsPIC33CK256MC103 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 dsPIC33CK256MC103 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 dsPIC33CK256MC103

This action is irreversible. Once you inhibit the ICSP writes, dsPIC33CK256MC103 cannot be re-programmed.

Debugging

NSDSP firmware contains all the necessary provisions for debugging dsPIC33CK256MC103 and may be debugged when debugging software becomes available.

dsPIC33CK256MC103 uses unordered halting, has 8 hardware breakpoints.

Debugging does not consume resources in the user space.
