NOTE:
*: In case where no EN/ENB pin’s condition written in the test condition field, EN=V_IN and ENB=V_SS.
**: V_DFL(T)=Setting detect voltage value
*1: The condition when the watchdog pin is ON.
The EN/ENB pin is CMOS input. For the XC6122 (pull-up resistor) and XC6124 (pull-down resistor),
supply current increases in the following values when the watchdog function is OFF.
