that's what I thought. I'm just not seeing it in the simulator.

I'm using version 7.10. I did some experimenting with the simulator
this morning and found the /TO bit is '1' following a WDT if:
-the device goes to sleep OR
-WDT timer expires and simulator is set to 'break on WDT'

/TO is correctly '0' if the WDT expires without going to sleep and
the simulator is set to 'reset on WDT'

This seems to be a simulator issue. Has anyone else observed this?
