Bits 5, 2:0 – WDP[3:0]: Watchdog Timer Prescaler 3, 2, 1, and 0
The WDP[3:0] bits determine the Watchdog Timer prescaling when the Watchdog Timer is
enabled. The different prescaling values and their corresponding Timeout Periods are shown in
Note:
1. If selected, one of the valid settings below 0b1010 will be used.
