#184964 - clarification
Responding to: Andy Peters's previous message
The watchdogs are great, but when you run the F120 at Full Tilt Boogie, you find yourself petting the dog more often than you'd like. The timer is 21 bits wide in all of the SiLabs parts I've used, and 21 bits at 98 MHz is 20 ms, so there it is.

clarification: this discussion is not, per se, about watchdogs, but about "reset supervisors"

"when you run the F120 at Full Tilt Boogie" well, the number of instruction that can be processed before a WD timeout is the same regardless of clock speed.
