Battery Voltage Management
The AMIS ? 30621 monitors the battery voltage by means
of one threshold and one shutdown level. The only condition
? <UV2> = ‘0’
? <Steploss> = ‘0’
to reset flags <UV2> and <StepLoss> is to recover by a
battery voltage higher than UV1 and to receive a
GetStatus or a GetFullStatus command.
