Figure 5.9 shows the typical temperature sensor error assuming a 1-point calibration at 25 °C. Parame-
ters that affect ADC measurement, in particular the voltage reference value, will also affect temper-
ature measurement.
A single-point offset measurement of the temperature sensor is performed on each device during produc-
tion test. The measurement is performed at 25 °C ±5 °C, using the ADC with the internal high speed refer-
ence buffer selected as the Voltage Reference. The direct ADC result of the measurement is stored in the
SFR registers TOFFH and TOFFL, shown in SFR Definition 5.13 and SFR Definition 5.14.
