4.25.4.16.3.3 Error acknowledged
Name:
OvercurrentAcknowledge01 to OvercurrentAcknowledge04
OvertemperatureAcknowledge
UndervoltageAcknowledge
This register contains bits used to acknowledge an overcurrent error, an undervoltage error and an overtemperature
error.
The errors are acknowledged with a rising edge. An existing error can only be acknowledged if the cause of the
error has been corrected.
