The timing and pin status at power-on are shown below.
(2) Reset operation (WDTRES) by overflow of watchdog timer (WDT)
Note
Remark
If the reset mode is set to reset upon overflow of the watchdog timer (WDT) (WDTM.WDM1 and WDTM.WDM0
bits = 10 or 11), the system is reset and each hardware is initialized to a specific state when WDT overflows
(INTWDT).
If the INTWDT interrupt request signal is generated, the RESF.RESFH4 bit is set to 1, indicating that internal
reset has occurred.
The operations during the reset period and after release of reset, other than the operation of the RESF
register, are the same as the reset operation by RESET pin input (see (1) Reset operation by RESET pin
input).
