6 ADC Pin Configuration

After setting the ADEN bit of the ADC control status register A, port PC[5:0],PE2,PE3 can be used as ADC input pin ADC[7:0] by configuring the MUX bits of the ADMUX register.

Bit 7 – ADEN: ADC Enable

Bits 3:0—MUXn: Analog Channel Selection[n=3:0]

The value of these bits selects which analog inputs are connected to the ADC as the following table.
