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%.
STPM13/14 only
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%.
