[En-Nut-Discussion] Watchdog Timer

I don't thin you'll be able to capture this information. They get lost
if you reset the cpu. And if the watchdog timer expires you have exactly
this situation, the cpu will be resettet. The only information that you
can obtain is the reset reason. So you could count how many times a
reset occurs, but you have no chance to determine the PC and SP values
at the moment of reset.

AFAIK no... But feel free to generate one. It should be possible

Bye,
