ADC_CAL—Analog to Digital Converter Calibration Values
Contains factory calibrated values for ADC gain and offset compensation. Each of the ten
supported modes has one byte of offset calibration and two bytes of gain calibration.
These values are read by user software to compensate ADC measurements as detailed in
Software Compensation Procedure Using Factory Calibration Data on page 119. The loca-
tion of each calibration byte is provided in Table 97.
