Sam3x8e Watchdog doesn't work while debugging

Sat Feb 13, 2016 2:27 am

I am using the sam3x8e with the watchdog enabled.

The watchdog will reset the micro when I am not debugging however, if I am debugging with the Atmel ICE3 debugger the watchdog does not work.
Also, when I am debugging if I view the watchdog config registers in the watch window (Atmel studio 6.2) the WDT_MR register does not update with the correct value when I step over it...

I assume the watchdog is suppose to work in debug mode considering there are config options to halt the watchdog timer when debugging or in idle mode.

Anyone experience similar behavior?
