Table 8-2.
Watchdog Timer Configuration
Note:
1. WDTON configuration bit set to “0“ means programmed and “1“ means unprogrammed.
Bit 4 – Res: Reserved Bit
This bit is reserved and will always read as zero.
Bit 3 – WDE: Watchdog System Reset Enable
WDE is overridden by WDRF in RSTFLR. This means that WDE is always set when WDRF is set. To clear WDE, WDRF
must be cleared first. This feature ensures multiple resets during conditions causing failure, and a safe start-up after the
failure.
Bits 5, 2:0 – WDP[3:0]: Watchdog Timer Prescaler 3 - 0
The WDP[3:0] bits determine the Watchdog Timer prescaling when the Watchdog Timer is running. The different
prescaling values and their corresponding time-out periods are shown in Table 8-3 on page 34.
