Description
Reserved.
Offset Calibration Temperature Sensor. ADC offset correction for temperature sensor channel,
represented as a twos complement number. The calibration resolution is 0.25 LSBs of the ADCDAT
LSB size.
Settings Description
Reserved.
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.
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.
Description
Reserved.
ADC Minimum Value Threshold. This value is a low ADCDAT threshold value. If a value less than
ADCMIN is measured by the ADC, the ADCINTSTA, Bit 4 is set to 1.
Description
Reserved.
ADCMIN Hysteresis Value. If a value less than ADCMIN is measured by the ADC, ADCINTSTA, Bit 4
is set. ADCINTSTA, Bit 4 is set until ADCDAT > ADCMIN + ADCMINSM, Bits[15:0].
