DIO17 is a dedicated SAG status pin that is set high when SAG Voltage alarm triggers. SAG Voltage
alarm status is checked every MUX cycle for low latency detection of AC fault conditions. Both the
instantaneous voltage alarm threshold and sample count for the SAG alarm are configurable. See CE
STATE and SAG Threshold registers for more information.
DIO14 is a configurable alarm pin that is an ‘OR function’ of several mask-able alarm bits. The alarm
status is checked and updated following an update of the measurement output registers (once every
Accumulation cycle). See registers E6 and E7 for mask settings.
