Analog-to-Digital Converter (ADC)

This section describes the 10-bit analog-to-digital converter (ADC).
Features of the ADC module include:
Ten ADC channels are available for sampling external sources at pins
PTC1/ATD9:PTC0/ATD8 and PTB7/ATD7:PTB0/ATD0. To achieve the
best possible accuracy, these pins are implemented as input-only pins
when the analog-to-digital (A/D) feature is enabled. An analog
multiplexer allows the single ADC converter to select one of the 10 ADC
channels as ADC voltage IN (ADCVIN). ADCVIN is converted by the
successive approximation algorithm. When the conversion is completed,
the ADC places the result in the ADC data register (ADRH and ADRL)
and sets a flag or generates an interrupt. See
