Hi Erik,

The WDT interrupt is disabled except for one particular piece of code that is not being used at the time I'm executing my forever loop.

When I was testing with the software reset I did have the WDT interrupt enabled, but the first thing I did in the interrupt function was to test to see if EWT was set, and if so cause the software reset to be executed. That should mean that the reset (if it had worked) would have happened 512 clocks - (interrupt latency and EWT test code) sooner that it would have without the interrupt enabled.
