The WDP2, WDP1 and WDP0 bits determine the Watchdog Timer prescaling when the Watch-
dog Timer is enabled. The different prescaling values and their corresponding time-out periods
are shown in Table 38.

1. The frequency of the Watchdog Oscillator is voltage dependent. The WDR – Watchdog Reset
WDP1
– instruction should always be executed before the Watchdog Timer is enabled. This ensures
that the reset period will be in accordance with the Watchdog Timer prescale settings. If the
Watchdog Timer is enabled without reset, the Watchdog Timer may not start counting from
zero.
