0x0

DISRPLPF

Set this bit to disable the low-pass filter in the total

reactive power datapath.

0x0

R/W

DISAPLPF

Set this bit to disable the low-pass filter in the total

active power datapath.

0x0

R/W

ININTEN

Set this bit to enable the digital integrator in the

Neutral Current channel.

0x0

R/W

VNOMC_EN

Set this bit to use the nominal phase voltage rms,

VNOM, in the computation of Phase C total

apparent power, CVA.

0x0

R/W

VNOMB_EN

Set this bit to use the nominal phase voltage rms,

VNOM, in the computation of Phase B total

apparent power, BVA.

0x0

R/W

VNOMA_EN

Set this bit to use the nominal phase voltage rms,

VNOM, in the computation of Phase A total

apparent power, AVA.

0x0

ZX_SRC_SEL

This bit selects whether data going into the zero-

crossing detection circuit comes before the high-

pass filter, integrator, and phase compensation or

afterwards.

0x0

R/W

0 After the high-pass filter, integrator, and phase

compensation.

1 Before the high-pass filter, integrator, and phase

compensation.

INTEN

Set this bit to enable the integrators in the phase

current channels. The neutral current channel

integrator is managed by the ININTEN bit in the

CONFIG0 register.

0x0

R/W

MTEN

Set this bit to enable multipoint phase and gain

compensation. If enabled, an additional gain

factor, xIGAIN0 through xIGAIN4, is applied to the

current channel based on the xIRMS current rms

amplitude and the MTTHR_Lx and MTTHR_Hx

0x0

R/W

HPFDIS

Set this bit to disable high-pass filters in all the

voltage and current channels.

ISUM_CFG

ISUM Calculation configuration.

0x0

R/W

00 ISUM = AI_PCF + BI_PCF + CI_PCF (for

approximated neutral current rms calculation).

01 ISUM = AI_PCF + BI_PCF + CI_PCF + NI_PCF (to

determine mismatch between neutral and phase

currents).

10 ISUM = AI_PCF + BI_PCF + CI_PCF - NI_PCF (to

determine mismatch between neutral and phase

currents).

11 ISUM = AI_PCF + BI_PCF + CI_PCF (for

approximated neutral current rms calculation).
