Bit
Location
1:0
Bit Mnemonic
PERSEL[1:0]
Default Value
00
Description
00: Phase A selected as the source of the voltage line period measurement.
01: Phase B selected as the source of the voltage line period measurement.
10: Phase C selected as the source of the voltage line period measurement.
11: reserved. When set, the ADE7854 / ADE7858 / ADE7868 / ADE7878 behave like PERSEL[1:0] = 00.
2
PEAKSEL[0]
1
PEAKSEL[2:0] bits can all be set to 1 simultaneously to allow peak detection on all three
phases simultaneously. If more than one PEAKSEL[2:0] bits are set to 1, then the peak
measurement period indicated in the PEAKCYC register decreases accordingly because zero
crossings are detected on more than one phase.
When this bit is set to 1, Phase A is selected for the voltage and current peak registers.

PEAKSEL[1]
PEAKSEL[2]
Reserved

000
When this bit is set to 1, Phase B is selected for the voltage and current peak registers.
When this bit is set to 1, Phase C is selected for the voltage and current peak registers.
Reserved. These bits do not manage any functionality.

Bit Mnemonic
WATTACC[1:0]
Default Value
00
Description
00: signed accumulation mode of the total and fundamental active powers. Fundamental
01: reserved. When set, the device behaves like WATTACC[1:0] = 00.
10: reserved. When set, the device behaves like WATTACC[1:0] = 00.
11: absolute accumulation mode of the total and fundamental active powers.
3:2
VARACC[1:0]
00
00: signed accumulation of the total and fundamental reactive powers. Total reactive powers
are available in the ADE7858 , ADE7868 , and ADE7878 . Fundamental reactive powers are
01: reserved. When set, the device behaves like VARACC[1:0] = 00.
10: the total and fundamental reactive powers are accumulated, depending on the sign of
the total and fundamental active power: if the active power is positive, the reactive power is
accumulated as is, whereas if the active power is negative, the reactive power is accumulated
with reversed sign.
11: reserved. When set, the device behave like VARACC[1:0] = 00.
5:4
CONSEL[1:0]
00
These bits select the inputs to the energy accumulation registers. IA’, IB’, and IC’ are IA, IB, and
00: 3-phase four wires with three voltage sensors.
01: 3-phase three wires delta connection.
10: 3-phase four wires with two voltage sensors.
11: 3-phase four wires delta connection.

REVAPSEL
0
0: The total active power on each phase is used to trigger a bit in the STATUS0 register as
follows: on Phase A triggers Bit 6 (REVAPA), on Phase B triggers Bit 7 (REVAPB), and on
1: The fundamental active power on each phase is used to trigger a bit in the STATUS0
register as follows: on Phase A triggers Bit 6 (REVAPA), on Phase B triggers Bit 7 (REVAPB),
and on Phase C triggers Bit 8 (REVAPC).
7
REVRPSEL
0
0: The total reactive power on each phase is used to trigger a bit in the STATUS0 register as
follows: on Phase A triggers Bit 10 (REVRPA), on Phase B triggers Bit 11 (REVRPB), and on
Phase C triggers Bit 12 (REVRPC). This bit is always 0 for the ADE7854 , ADE7858 , and
1: The fundamental reactive power on each phase is used to trigger a bit in the STATUS0
register as follows: on Phase A triggers Bit 10 (REVRPA), on Phase B triggers Bit 11 (REVRPB),
and on Phase C triggers Bit 12 (REVRPC).
