Note: If WT/IT is modified when the WDT is running, the up-count may not be performed correctly.
Bit 5—Reset Select (RSTS): Selects the type of reset when WTCNT overflows in watchdog
timer mode. In interval timer mode, this setting is ignored.

Note: RESETOUT is output.
Bit 4—Watchdog Timer Overflow (WOVF): Indicates that the WTCNT has overflowed in
watchdog timer mode. This bit is not set in interval timer mode.

Bit 3—Interval Timer Overflow (IOVF): Indicates that WTCNT has overflowed in interval
timer mode. This bit is not set in watchdog timer mode.

Bits 2 to 0—Clock Select 2 to 0 (CKS2 to CKS0): These bits select the clock to be used for the
WTCNT count from the eight types obtainable by dividing the peripheral clock. The overflow
period in the table is the value when the peripheral clock (P ) is 15 MHz.
