Description

TERMSEL3[1]

Phase B is included in the CF3 outputs calculations.

TERMSEL3[2]

Phase C is included in the CF3 outputs calculations.

10:9

ANGLESEL[1:0]

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.

VNOMAEN

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.

VNOMBEN

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.

VNOMCEN

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.

SELFREQ

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.

Reserved

This bit is 0 by default, and it does not manage any functionality.
