*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.
*2: These LVD settings cannot be used to reliably generate a reset before voltage dips below minimum guaranteed MCU operation
voltage, as these detection levels are below the minimum guaranteed MCU operation voltage (1.09 V).
Notes:
−
The detection/release threshold values of LVDL2 channel is potentially below supply range defined in
−
Please use this LVDL2 channel with your own risk.
−
Please monitor the external power supplies on the PCB if needed.
