Section 12 Watchdog Timer (WDT)
12.3.3
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 12.5.
12.3.4
With WDT_0 the WOVF bit in RSTCSR is set to 1 if TCNT overflows in watchdog timer mode.
If TCNT overflows while the RSTE bit in RSTCSR is set to 1, an internal is generated for the
entire chip. (WOVI interrupt is not generated.) This timing is illustrated in figure 12.6.
