Section 11 Watchdog Timer
11.4
During interval timer mode operation, an overflow generates an interval timer interrupt (WOVI).
The interval timer interrupt is requested whenever the OVF flag is set to 1 in TCSR.

11.5.1
If a timer counter clock pulse is generated during the T
takes priority and the timer counter is not incremented. Figure 11.8 shows this operation.
