Internal Reset in Watchdog Timer Mode
The H8S/2357 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 falg, therefore, read RSTCSR after the
WDTOVF
signal*
goes high, then write 0 to the WOVF flag.
Note: * The
WDTOVF
pin function is not available in the F-ZTAT version, the H8S/2398, H8S/2394, H8S/2392 or
H8S/2390.
