Changing the conversion channel
The application can change channels during conversion. When software modifies the
CH[3:0] bits in the ADCCSR register, the current conversion is stopped, the EOC bit is
cleared, and the A/D converter starts converting the newly selected channel.
Low power modes
The A/D converter may be disabled by resetting the ADON bit. This feature allows reduced
power consumption when no conversion is needed.
