Section 12 Watchdog Timer (WDT)
12.3.4
The WOVF flag is set to 1 if TCNT overflows during watchdog timer operation. At the same time,
the WDTOVF signal goes low. If TCNT overflows while the RSTE bit in RSTCSR is set to 1, an
internal reset signal is generated for the entire H8S/2350 Group chip. Figure 12.7 shows the timing
in this case.
