Section 13 Watchdog Timer
13.4
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.
13.5
13.5.1
If a timer counter clock pulse is generated during the T
takes priority and the timer counter is not incremented. Figure 13.8 shows this operation.
