SUM2SIGN
Default Value
0
Description
0: if the sum of all phase powers in the CF2 datapath is positive.
1: if the sum of all phase powers in the CF2 datapath is negative. Phase powers in the CF2
datapath are identified by Bits[5:3] (TERMSEL2[x]) of the COMPMODE register and by
Bits[5:3] (CF2SEL[x]) of the CFMODE register.

SUM3SIGN
0
0: if the sum of all phase powers in the CF3 datapath is positive.
1: if the sum of all phase powers in the CF3 datapath is negative. Phase powers in the CF3
datapath are identified by Bits[8:6] (TERMSEL3[x]) of the COMPMODE register and by
Bits[8:6] (CF3SEL[x]) of the CFMODE register.

INTEN
Default Value
0
Description
Integrator enable. When this bit is set to 1, the internal digital integrator is enabled for use in
meters utilizing Rogowski coils on all 3-phase and neutral current inputs.
When this bit is cleared to 0, the internal digital integrator is disabled.

0
Reserved. These bits do not manage any functionality.
When this bit is set to 1, the voltage channel outputs are swapped with the current channel
outputs. Thus, the current channel information is present in the voltage channel registers
and vice versa.

When this bit is set to 1, the voltage channel ADCs behave as if the voltage inputs were put
to ground.
When this bit is set to 1, the current channel ADCs behave as if the voltage inputs were put
to ground.
When this bit is set to 1, the HSDC serial port is enabled and HSCLK functionality is chosen at
CF3/HSCLK pin.
When this bit is cleared to 0, HSDC is disabled and CF3 functionality is chosen at CF3/HSCLK pin.

00
When this bit is set to 1, a software reset is initiated.
These bits decide what phase voltage is considered together with Phase A current in the
power path.
00 = Phase A voltage.
01 = Phase B voltage.
10 = Phase C voltage.
11 = reserved. When set, the ADE7854 / ADE7858 / ADE7868 / ADE7878 behave like VTOIA[1:0] =
00.

VTOIB[1:0]
00
These bits decide what phase voltage is considered together with Phase B current in the
power path.
00 = Phase B voltage.
01 = Phase C voltage.
10 = Phase A voltage.
11 = reserved. When set, the ADE7854 / ADE7858 / ADE7868 / ADE7878 behave like VTOIB[1:0] =
00.

VTOIC[1:0]
00
These bits decide what phase voltage is considered together with Phase C current in the
power path.
00 = Phase C voltage.
01 = Phase A voltage.
10 = Phase B voltage.
11 = reserved. When set, the ADE7854 / ADE7858 / ADE7868 / ADE7878 behave like VTOIC[1:0] =
