*1: If the fluctuation of the power supply is faster than the low voltage detection time, there is a possibility to

generate or release after the power supply voltage has exceeded the detection voltage range.

*2: Please suppress the change of the power supply within the range of the power-supply voltage regulation to

do a low voltage detection by detecting voltage (VDL).
