The eight analog inputs to the Multiplexer. Active channels are selected
based on the contents of bits b3–b0 of the Configuration register. Refer
to section titled MUX for more details.
This pin is another analog input pin used as a pseudo ground when the
multiplexer is configured in single-ended mode.
Positive reference input. The operating voltage range for this input is
