Temperature Sensor Offset High Order Bits.
The temperature sensor offset registers represent the output of the ADC when mea-
suring the temperature sensor at 0 °C, with the voltage reference set to the internal
regulator. The temperature sensor offset information is left-justified. One LSB of this
measurement is equivalent to one LSB of the ADC output under the measurement
conditions.
