dsPIC33CDVL64MC106 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 dsPIC33CDVL64MC106 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 dsPIC33CDVL64MC106
This action is irreversible. Once you inhibit the ICSP writes, dsPIC33CDVL64MC106 cannot be re-programmed.
We have measured time necessary to program and verify dsPIC33CDVL64MC106.
|Operation||FCKSM=0x||FCKSM=1x||Programming and Verification||1.6s||2.2s||Programming only||1.5s||1.5s||Verification only||1.2s||1.2s|
The measurements reflect the time necessary to program/verify the entire chip, including all user programmable memory areas.
NSDSP firmware contains all the necessary provisions for debugging dsPIC33CDVL64MC106 and may be debugged when debugging software becomes available.
