Offset Calibration for Low Power TIA0. Represented as a twos complement
number. The calibration resolution is 0.25 LSBs of the ADCDAT LSB size.
0x3FFF 4095.75 (maximum positive offset calibration value).
0x0001 0.25 (minimum positive offset calibration value).
0x0000 0 (no offset adjustment).
0x7FFF −0.25 (minimum negative offset calibration value).
0x4000 −4096.0 (maximum negative offset calibration value).
Description

Gain Error Calibration for Low Power TIA0. ADC offset correction in TIA
measurement mode, represented as a twos complement number.
2 (maximum positive gain adjustment).
1.000061 (minimum positive gain adjustment).
1.0. ADC result multiplied by 1. No gain adjustment. Default value.
0.999939 (minimum negative gain adjustment).
0.5. ADC result multiplied by 0.5.
0.000061 (maximum negative gain adjustment).
0. Invalid value. Results in an ADC result of 0.
