Phase B is included in the CF3 outputs calculations.
Phase C is included in the CF3 outputs calculations.
Description
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.
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 the VNOM[23:0] register
instead of the regular measured rms phase voltage.
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 the VNOM[23:0] register
instead of the regular measured rms phase voltage.
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 the VNOM[23:0] register
instead of the regular measured rms phase voltage.
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 is 0 by default, and it does not manage any functionality.
