Section 10 On-Chip Oscillation Circuits
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.

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 (Pφ) is 15 MHz.
