Description
1: Phase A is in no load condition based on apparent power. Bit set together with Bit 2
(VANLOAD) in the STATUS1 register.
0: Phase B is out of no load condition based on apparent power.
1: Phase B is in no load condition based on apparent power. Bit set together with Bit 2
(VANLOAD) in the STATUS1 register.
0: Phase C is out of no load condition based on apparent power.
1: Phase C is in no load condition based on apparent power. Bit set together with Bit 2
(VANLOAD) in the STATUS1 register.
Reserved. These bits are always 0.
Description
Setting all TERMSEL1[2:0] to 1 signifies the sum of all three phases is included in the CF1
output. Phase A is included in the CF1 outputs calculations.
Phase B is included in the CF1 outputs calculations.
Phase C is included in the CF1 outputs calculations.
Setting all TERMSEL2[2:0] to 1 signifies the sum of all three phases is included in the CF2
output. Phase A is included in the CF2 outputs calculations.
Phase B is included in the CF2 outputs calculations.
Phase C is included in the CF2 outputs calculations.
Setting all TERMSEL3[2:0] to 1 signifies the sum of all three phases is included in the CF3
output. Phase A is included in the CF3 outputs calculations.
Phase B is included in the CF3 outputs calculations.
Phase C is included in the CF3 outputs calculations.
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 VNOM register instead
of 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 VNOM register instead
of 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 VNOM register instead
of regular measured rms phase voltage.
When the ADE7880 is connected to 50 Hz networks, this bit should be cleared to 0 (default
value). When the ADE7880 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.
Description
Phase currents gain selection.
000: gain = 1.
001: gain = 2.
010: gain = 4.
011: gain = 8.
100: gain = 16.
