12.4
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.
If an NMI request has been chosen in the watchdog timer mode, an NMI request is generated
when a TCNT overflow occurs.

If a timer counter clock pulse is generated during the T
takes priority and the timer counter is not incremented. Figure 12.8 shows this operation.
