Section 11 Watchdog Timer
11.5.5
Internal Reset in Watchdog Timer Mode
The H8S/2345 Group is not reset internally if TCNT overflows while the RSTE bit is cleared to 0
during watchdog timer operation, but TCNT and TSCR of the WDT are reset.
TCNT, TCSR, and RSTCR cannot be written to while the WDTOVF signal * is low. Also note that
a read of the WOVF flag is not recognized during this period. To clear the WOVF flag, therefore,
read TCSR after the WDTOVF signal * goes high, then write 0 to the WOVF flag.
Note: * The WDTOVF pin function is not supported by the F-ZTAT version.
