KWDT - Kill Watchdog Timer Bit
1 (set)
Enable watchdog “kill” feature.
0 (clear) –
Disable watchdog “kill” feature.
When this watchdog “kill” feature is set by writing a logic “1” to this bit immediately after a reset,
the watchdog timer will be disabled when the MCU in Stop or Wait mode. The default for the
watchdog timer “kill” feature at reset is disabled.
Reading this bit will show the value of rst write after Reset or the default value upon reset.
WDTOF - Watchdog Timer Time-out Flag
1 (set)
A watchdog timer time-out has occurred.
0 (clear) –
A watchdog timer time-out has not occurred.
This ag is cleared by writing a logic “0” to this bit. Writing a logic “1” to this bit will reset the
watchdog timer counter, and hence avoiding a watchdog time-out. The write does not affect the
time-out ag.
