Description
8
TERMSEL3[2]
1
Phase C is included in the CF3 outputs calculations.
10:9
ANGLESEL[1:0]
00
00: the angles between phase voltages and phase currents are measured.
01: the angles between phase voltages are measured.
10: the angles between phase currents are measured.
11: no angles are measured.
11
VNOMAEN
0
When this bit is 0, the apparent power on Phase A is computed regularly.
When this bit is 1, the apparent power on Phase A is computed using VNOM register instead
of regular measured rms phase voltage.
12
VNOMBEN
0
When this bit is 0, the apparent power on Phase B is computed regularly.
When this bit is 1, the apparent power on Phase B is computed using VNOM register instead
of regular measured rms phase voltage.
13
VNOMCEN
0
When this bit is 0, the apparent power on Phase C is computed regularly.
When this bit is 1, the apparent power on Phase C is computed using VNOM register instead
of regular measured rms phase voltage.
14
SELFREQ
0
When the ADE7878 is connected to 50 Hz networks, this bit should be cleared to 0 (default
value). When the ADE7878 is connected to 60 Hz networks, this bit should be set to 1. This
bit does not have any consequence for ADE7854, ADE7858, and ADE7868.
15
Reserved
0
This bit is 0 by default and it does not manage any functionality.
