Address: 08H
Type: Read/Write
Default Value: 1000H
Bit Name Description
15:0 SagTh
Voltage sag threshold level.
0xFFFF map to ADC output full-scale peak.
Address: 09H
Type: Read/Write
Default Value: 0400H
Bit Name Description
15:0 PhaseLossTh
PhaseLoss threshold level
0xFFFF map to ADC output full-scale peak.
Address: 0AH
Type: Read/Write
Default Value: FFFFH
Bit Name Description
15:0 INWarnTh0
Neutral current (calculated) warning threshold.
Threshold for calculated (Ia + Ib +Ic) N line rms current. Unsigned 16 bit, unit 1mA.
If N line rms current is greater than the threshold, the INOv0ST bit (b7, EMMState0) bit is asserted if enabled. Refer to 3.7.5 Neu-
tral Line Overcurrent Detection.

Over Current threshold.
0xFFFF maps to ADC output full-scale peak.
Address: 0CH
Type: Read/Write
Default Value: 1324H
Bit Name Description
15:0 FreqLoTh Low threshold for frequency detection.
