*1: If the power fluctuation time is less than the low-voltage detection time (TRd) and has passed the detection voltage range, the
detection may occur or be canceled after the supply voltage has passed the detection voltage range.
Notes:
− The detection/release threshold values of LVDL0 channel is potentially below supply range defined in 9.1.2 Recommended
operating condition.
