0x492 ACCMODE [15:9] RESERVED Reserved. 0x0 R
8 SELFREQ Use this bit to configure the IC for a 50 Hz or
60 Hz system. This setting is used in the
fundamental power measurements and to set the
default line period used for VRMS½, 10 cycle rms/
12 cycle rms and resampling calculations if a
zero-crossing is not present.
0x0 R/W
0 50 Hz.
1 60 Hz.
7 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.
0x0 R/W
[6:4] VCONSEL 3-wire and 4-wire hardware configuration
selection.
0x0 R/W
000 4-wire wye.
001 3-wire delta. VB' = VA − VC.
010 4-wire wye, nonBlondel compliant. VB' = −VA − VC.
011 4-wire delta, nonBlondel compliant. VB' = −VA.
100 3-wire delta. VA' = VA − VB; VB' = VA − VC; VC' =
VC − VB.
[3:2] VARACC Total and fundamental reactive power accumula-
tion mode for energy registers and CFx pulses.
0x0 R/W
00 Signed accumulation mode.
01 Absolute value accumulation mode.

Positive accumulation mode.
11 Negative accumulation mode.
[1:0] WAT TACC Total and fundamental active power accumulation
mode for energy registers and CFx pulses. See
VARACC.

0x493 CONFIG3 [15:12] OC_EN Overcurrent detection enable. OC_EN[3:0] bits
can all be set to 1 simultaneously to allow
overcurrent detection on all three phases and/or
neutral simultaneously.
0xF R/W
Bit 12. When OC_EN[3] is set to 1, Phase A is
selected for the overcurrent detection.
Bit 13. When OC_EN[2] is set to 1, Phase B is
selected for the overcurrent detection.
Bit 14. When OC_EN[1] is set to 1, Phase C is
selected for the overcurrent detection.
Bit 15. When OC_EN[0] is set to 1, the neutral line
is selected for the overcurrent detection.

[4:2] PEAKSEL Set this bit to select which phase(s) to monitor
peak voltages and currents on. Write 1 to PEAKSEL,
Bit 0 to enable Phase A peak detection. Similarly,
PEAKSEL, Bit 1 enables Phase B peak detection, and
PEAKSEL, Bit 2 enables Phase C peak detection.
