Section 15 Watchdog Timer (WDT)
15.4.2
To use the WDT as an interval timer, set the WT/IT bit to 0 and the TME bit to 1 in TCSR.
When the WDT is used as an interval timer, an interval timer interrupt (WOVI) is generated each
time the TCNT overflows. Therefore, an interrupt can be generated at intervals.
When the TCNT overflows in interval timer mode, an interval timer interrupt (WOVI) is requested
at the same time the OVF bit in the TCSR is set to 1.
15.5
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. The OVF flag
must be cleared to 0 in the interrupt handling routine.
