Section 14 Watchdog Timer (WDT)
14.4
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. OVF must be
cleared to 0 in the interrupt handling routine. When NMI interrupt request generation is selected in
watchdog timer mode, an overflow generates an NMI interrupt request.

14.5.1
If a timer counter clock pulse is generated during the T
takes priority and the timer counter is not incremented. Figure 14.6 shows this operation.
