On devices with an internal voltage reference and internal temperature sensor, there is an internal connection between these modules and the ADC. There are also additional ADC Data registers to store the results of these conversions. Like the standard ADC channels, these results can be right aligned or left aligned. Value Addition mode can also be used and, in that case, the 14-bit result is always left aligned. Prior to converting the temperature sensor or internal reference all other AD input channels should be disabled by setting the ANSi (analog select) bits to 0.
