1: Timer enabled
Timer Mode Select
Selects whether to use the WDT as a watchdog timer
or an interval timer.
0: Use as interval timer
1: Use as watchdog timer
Note: If WT/IT is modified when the WDT is running,
Reset Select
Selects the type of reset when the WTCNT overflows
in watchdog timer mode. In interval timer mode, this
setting is ignored.
0: Power-on reset
1: Manual reset
Watchdog Timer Overflow
Indicates that the WTCNT has overflowed in
watchdog timer mode. This bit is not set in interval
timer mode.
0: No overflow
1: WTCNT has overflowed in watchdog timer mode
Interval Timer Overflow
Indicates that the WTCNT has overflowed in interval
timer mode. This bit is not set in watchdog timer
mode.
