WDTMOD is a special function register to set the overflow period of the watchdog timer.
[Description of Bits]
• WDT1-0 (bits 1-0)
Initial value
WDTMOD
These bits are used to select an overflow period of the watchdog timer.
The WDT1 and WDT0 bits set a overflow period (TWOV) of the WDT counter. One of 125ms, 500ms, 2s, and 8s
can be selected.
