Register 43 April 2, 2013
INWarnTh0
Neutral Current (Calculated) Warning Threshold
INWarnTh1
Neutral Current (Sampled) Warning Threshold
THDNUTh
Voltage THD Warning Threshold
THDNITh
Current THD Warning Threshold
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 INOv0 bit (b14, SysStatus1) will be asserted if enabled. Refer to 3.8.4.2
Computed N-Line.
Address: 0BH
Type: Read/Write
Default Value: FFFFH
Bit Name Description
15:0 INWarnTh1
Neutral Current (Sampled) Warning threshold.
Threshold for sampled (from ADC) N line rms current. Unsigned 16 bit, unit 1mA.
If N line rms current is greater than the threshold, The INOv1 bit (b15, SysStatus1) will be asserted if enabled. Refer to 3.8.4.1
Sampled N-Line.
Address: 0CH
Type: Read/Write
Default Value: FFFFH
Bit Name Description
15:0 THDNUTh
Voltage THD Warning threshold.
Voltage THD+N Threshold. Unsigned 16 bit, unit 0.01%.
Exceeding the threshold will assert the THDUOv bit (b11, SysStatus1) if enabled.
Address: 0DH
Type: Read/Write
Default Value: FFFFH
Bit Name Description
15:0 THDNITh
Current THD Warning threshold.
Current THD+N Threshold. Unsigned 16-bit, unit 0.01%.
Exceeding the threshold will assert the THDIOv bit (b10, SysStatus1) if enabled.
