Bit 6—Timer Mode Select (WT/IT): Selects whether to use the WDT as a watchdog timer or an
interval timer.

1
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 the WTCNT overflows in watchdog
timer mode. In interval timer mode, this setting is ignored.

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 4: WOVF
0
1
Bit 3—Interval Timer Overflow (IOVF): Indicates that the WTCNT has overflowed in interval
timer mode. This bit is not set in watchdog timer mode.
Bit 3: IOVF

Bits 2 to 0—Clock Select 2–0 (CKS2–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.
