Bandgap Temperature compensation bits. See
4-bit unsigned data for compensation of phase error, 0°+0.576°.
16 values are possible with a compensation step of 0.0384°. When CPH=0 the
compensation is 0°, when CPH=15 the compensation is 0.576°.
8-bit unsigned data for voltage channel calibration.
256 values are possible. When CHV is 0 the calibrator is at -12.5 % of the
nominal value. When CHV is 255 the calibrator is at +12.5 %. The calibration
step is then 0.098%.
8-bit unsigned data for primary current channel calibration.
256 values are possible. When CHP is 0 the calibrator is at -12.5 % of the
nominal value. When CHP is 255 the calibrator is at +12.5 %. The calibration
step is then 0.098%.
8-bit unsigned data for secondary current channel calibration.
256 values are possible. When CHS is 0 the calibrator is at -12.5 % of the
nominal value. When CHS is 255 the calibrator is at +12.5 %. The calibration
step is then 0.098 %.
