Description
Setting all TERMSEL1[2:0] to 1 signifies the sum of all 3 phases is included in CF1 output
Phase A is included in CF1 outputs calculations
Phase B is included in CF1 outputs calculations
Phase C is included in CF1 outputs calculations
Setting all TERMSEL2[2:0] to 1 signifies the sum of all 3 phases is included in CF2 output
Phase A is included in CF2 outputs calculations
Phase B is included in CF2 outputs calculations
Phase C is included in CF2 outputs calculations
Setting all TERMSEL3[2:0] to 1 signifies the sum of all 3 phases is included in CF3 output
Phase A is included in CF3 outputs calculations
Phase B is included in CF3 outputs calculations
Phase C is included in 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[23:0] 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[23:0] 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[23:0] register instead of regular measured
rms phase voltage.
When the ADE7854 is connected to 50Hz networks, this bit should be cleared to 0 (default
value). When the ADE7854 is connected to 60Hz networks, this bit should be set to 1.
This bit does not manage any functionality.
Description
