Detailed Description

This module provides access to the ADC.

This module provides high level access to the Analog-to-Digital Converter. It uses optionally AREFA as external reference and connects ADC1, ADC2, ADC3 and ADC4 with Channel 0, 1, 2 and 3. The module uses single-ended inputs the the resolution of the conversion is 12 bits.
