So the bottom line would be that at high temperartures the watchdog osc
run so fast that the watchdog timeout period is impractically short for
a certain application? I can understand that, but IMHO it is
insufficient motivation for the blunt advice *do not use the watchdog*.
Just know the timeout figure and kick the dog often enough.
