Section 11 Watchdog Timer (WDT)
11.4.2
When the WDT is used as an interval timer, an interval timer interrupt (WOVI) is generated each
time the TCNT overflows, as shown in figure 11.3. Therefore, an interrupt can be generated at
intervals.
When the TCNT overflows in interval timer mode, an interval timer interrupt (WOVI) is requested
at the same time the OVF bit of TCSR is set to 1. The timing is shown in figure 11.4.
