OPERATION
(1) When the power supply, VDD pin voltage becomes more than the released voltage (+VDET), after the released
delay time (or the power on reset time tPLH), the output of RESETB becomes "H" level.
(2) When the SCK pulse is input, the watchdog timer (WDT) is cleared, and CT pin mode changes from the
discharge mode to the charge mode. When the CT pin voltage becomes higher than Vref2H, the mode will
change into the discharge mode, and next watchdog time count starts.
(3) Unless the SCK pulse is input, WDT will not be cleared, and during the charging period of CT pin,
RESETB
="L".
(4) When the VDD pin becomes lower than the detector threshold voltage(-VDET), RESETB outputs "L".
(5) If "L" signal is input to the INH pin, the RESETB outputs "H", regardless the SCK clock state.
(6) During the "L" period of INH pin, the voltage detector monitors the supply voltage.
) Vref2H : CT pin voltage at the end of WDT timeout period.
) Vref2L : CT pin voltage at the begin of WDT timeout period.
