13.4.3
The OVF flag is set to 1 if TCNT overflows during interval timer operation. At the same time, an
interval timer interrupt (WOVI) is requested. This timing is shown in figure 13.4.
When NMI request is chosen in watchdog timer mode for WDT_1, TCNT overflow sets the OVF
flog to 1. At the same time, NMI interrupt is requested.
