time
*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: This LVD 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 (1.05V).
*3: After the brown-out event where the voltage level dips below the detection threshold for less than this time, the detection may
occur or be canceled.
Notes:
−
The detection/release threshold values of LVDL0 channel is potentially below supply range defined in 9.1.2 Recommended
operating condition.
