This bit field selects which single-ended analog input is connected
to the ADC. If these bits are changed during a conversion, the change will not
take effect until this conversion is complete.

Note: Not all pins of a port are
available on devices with low pin counts. Check the Pinout Diagram and/or the I/O
Multiplexing table for details.
