Data register high (ADCDRH)

Data register low (ADCDRL)

2:0 CH[2:0]

Channel Selection

These bits are set and cleared by software. They select the analog input to convert

as follows:

000: Channel pin = AIN0

001: Channel pin = AIN1

010: Channel pin = AIN2

011: Channel pin = AIN3

100: Channel pin = AIN4

Note: A write to the ADCCSR register (with ADON set) aborts the current

conversion, resets the EOC bit and starts a new conversion.
