[14:0] VALUE Gain Calibration Temperature Sensor Channel. ADC gain correction for temperature sensor
channel. Stored as a signed number. Bit 14 is the sign bit and Bits[13:0] represent the fractional
part.
0x4000 R/W
0x7FFF 2 (maximum positive gain adjustment).
0x4001 1.000061 (minimum positive gain adjustment).
0x4000 1.0. ADC result multiplied by 1. No gain adjustment. Default value.
0x3FFF 0.999939 (minimum negative gain adjustment).
0x2000 0.5. ADC result multiplied by 0.5.
0x0001 0.000061 (maximum negative gain adjustment).
0x0000 0. Invalid value. Results in ADC result of 0x8000.
