14.3.5
The ADC module supports up to 28 separate analog inputs. An input is selected for conversion through the
ADCH channel select bits.
14.4
These memory mapped registers control and monitor operation of the ADC:
14.4.1
This section describes the function of the ADC status and control register (ADC1SC1). Writing ADC1SC1
aborts the current conversion and initiates a new conversion (if the ADCH bits are equal to a value other
than all 1s).
