5.2.
The typical temperature sensor transfer function is shown in Figure 5.2. The output voltage (V
ADC input when the temperature sensor is selected by bits AMX0P4-0 in register AMX0P.
Note that parameters which affect ADC measurement, in particular the voltage reference value, will also affect
temperature measurement.
