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

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

*2: When setting the power supply fluctuation to this standard or less, it is possible to suppress the slope detection.

This is the standard when the power supply fluctuation is stable.

*3: This time is to start the slope detection at next power on after power down and internal charge loss.
