The WDT has a nominal time-out period of 18 ms, (with no postscaler). The time-out period var-
ies with temperature, V
time-outs are desired, a postscaler with a division ratio of up to 1:128 can be assigned to the
WDT, under software control, by writing to the OPTION_REG register. Thus, time-out periods of
up to 2.3 seconds can be realized.

The TO bit in the STATUS register will be cleared upon a Watchdog Timer time-out (WDT Reset
and WDT wake-up).
It should also be taken in account that under worst case conditions (V
ture = Maximum, maximum WDT postscaler) it may take several seconds before a WDT time-out
occurs.
