SELFREQ

This bit is used to configure the IC for a 50 Hz or

60 Hz system. This setting is used in the

fundamental reactive power measurement and to

set the default line period used for resampling

calculations if a zero crossing is not present.

0x0

R/W

0 50 Hz.

1 60 Hz.

ICONSEL

Set this bit to calculate the current flowing

through IB from the IA and IC measurements. If

this bit is set, IB = −IA − IC.

000 4-wire wye.

001 3-wire delta. VB' = VA − VC.

010 4-wire wye, non-Blondel compliant. VB' = −VA −

VC.

011 4-wire delta, non- Blondel compliant. VB' = −VA.

100 3-wire delta. VA' = VA − VB; VB' = VA − VC; VC' =

VC − VB.
