Selects the current linearity offset calibration method. See the Calibrating Current Offset section for
more information.
0 = IRMS
1 = IRMS + OFFS
These bits select the coefficient used in calculating apparent power.
00 = 1-phase, 3-wire (1P3W), or 3-phase, 4-wire (3P4W) (C = 1)
01 = 3-phase, 3-wire (3P3W) (C = 3/2)
