Analog-to-Digital Converter (S08ADC16)
factor, with the decimal point fixed between MG15 and MG14. This register must be written by the user
with the value described in the calibration procedure or the gain error specifications may not be met.
21.4.11 ADC Plus-Side General Calibration Value Registers (ADCCLPx)
The Plus-Side General Calibration Value Registers (ADCCLPx) contain calibration information that is
generated by the calibration function. These registers contain seven calibration values of varying widths:
CLP0[5:0], CLP1[6:0], CLP2[7:0], CLP3[8:0], CLP4[9:0], CLPS[5:0], and CLPD[5:0]. ADCCLPx are
automatically set once the self calibration sequence is done (CAL is cleared). If these registers are written
by the user after calibration, the linearity error specifications may not be met.
