13.3.4
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 chip. Figure 13.7 shows the timing in this case.
Note: * The WDTOVF pin function cannot be used in the F-ZTAT versions.
