CRC_DIS

Disable CRC Check. Set this

bit to disable CRC check on

Host SPI command.

ICONSEL

Phase B Current Calculation

Selection. Set this bit to

calculate the current flowing

through BI from the AI and CI

measurements. If this bit is set,

BI = −AI − CI.

3-Wire Delta. BV' = AV − CV.

010

4-Wire Wye, Non-Blondel

Compliant. BV' = −AV − CV.

011

4-Wire Wye, Non-Blondel

Compliant. BV' = −AV.

R/W

ISUM = AI_PCF +

BI_PCF + CI_PCF. For

approximated neutral current

RMS calculation.

ISUM = AI_PCF + BI_PCF

+ CI_PCF + AUXx_PCF. To

determine mismatch between

neutral and phase currents.

ISUM = AI_PCF + BI_PCF

+ CI_PCF − AUXx_PCF. To

determine mismatch between

neutral and phase currents.

DIP_SWELL_ONE_IRQ_MODE

Dip and Swell One-Cycle

Interrupt Mode Selection.
