Gets the I/O device's offset reference and A/D channel mode. The reference
parameter represents which source each analog input is compared against. The mode
parameter is the overall configuration of the channels and whether they are single-ended or paired.
For more information on the returned parameter values, see A/D Voltage Reference values and A/D Channel Modes.
