13.3.4
When the WDT is operating in interval timer mode, an interval timer interrupt is generated each
time the counter overflows. This enables interrupts to be generated at fixed intervals.
1. Clear the WT/IT bit in WTCSR to 0, select the count clock with bits CKS2 to CKS0, and set
2. When the TME bit in WTCSR is set to 1, the count starts in interval timer mode.
3. When the counter overflows, the WDT sets the IOVF flag in WTCSR to 1, and sends an
the initial value in WTCNT.
interval timer interrupt request to INTC. The counter continues counting.
