Notes:
−
*1: 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 (3.5 V).
−
*2: 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.
−
*3: 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.
