When set, disables automatic determination of the filter parameters for the harmonic filter coefficient. If
set by the host software, the host must set a value in the A1HARM filter coefficient register to
establish the operating frequency of this filter if harmonic-mode calculations are used. When cleared,
the MAXQ3183 automatically determines the value of the harmonic filter coefficient based on the
measured line frequency and the harmonic-order requested (AUX_CFG.ORDH).
When set, disables automatic determination of the filter parameters for the fundamental-mode filter. If
set by the host software, the host must set a value in the A1FUND filter coefficient register to establish
the operating frequency of this filter if fundamental-mode calculations are used. When clear, the
MAXQ3183 automatically determines the value of the fundamental-mode filter coefficient based on the
measured line frequency.
When set, fundamental-mode calculations are disabled. Fundamental-mode calculations provide
information about power and energy that are consumed only at the fundamental line frequency apart
from any harmonics that could be present. Setting this bit disables all fundamental frequency registers
but allows the MAXQ3183 to calculate other parameters at a higher rate. Set this bit when (1)
fundamental mode values do not need to be read, and (2) R_ADCRATE needs to be reduced below its
default value.
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)
10 = three voltages, three currents (3V3A) (C = 3/3)
