Note the following about the temperature sensor:
When the temperature sensor is selected, user code must select the internal reference via the AXREF bit and clear the AUNI bit (ADC1CON.5) to select bipolar coding.
Chop mode must be enabled for correct temperature sensor operation.
The temperature sensor is factory calibrated to yield conversion results 800000H at 0°C (ADC chop on).
A +1°C change in temperature results in a +1 LSB change in the ADC1H register ADC conversion result.
The temperature sensor is not available on the ADuC847 or ADuC848.
