11.3.4
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/2345 Group chip. Figure 11.7 shows the timing
in this case.
Note: * The WDTOVF pin function is not supported by the F-ZTAT version.
