I've used NOWDT in CCS with the F876 and it works fine. So:
- most programming software allows you to manually change the settings
of the configuration bits. Did the watchdog inadvertently get turned
on that way?
- Are you sure it's a watchdog reset? How do you know?
- are you using an emulator? With the ICE2000, for example, you change
the watchdog stuff via menu options - the settings in the hex file
don't have any effect.
