Label
Watchdog timer register map and reset values
7 WDGA Activation bit.
This bit is set by software and only cleared by hardware after a reset. When WDGA
= 1, the watchdog can generate a reset.
0: Watchdog disabled
1: Watchdog enabled
These bits contain the decremented value. A reset is produced when it rolls over
from 40h to 3Fh (T6 becomes cleared).
