NOTE: By default, both analog and digital low-voltage detections are enabled, which causes approximately 25µA of
current consumption from the power supply. To minimize this power consumption, both low-voltage detections should be
disabled before entering Stop mode.
ALVDIS Analog Low Voltage Detect Disable.
bit 7 0 = Enable Detection of Low Analog Supply Voltage
1 = Disable Detection of Low Analog Supply Voltage
ALVD2−0 Analog Voltage Detection Level.
