Bit 7 – INVERT Invert AC Output

Writing a '1' to this bit enables inversion of the output of the AC. This effectively inverts the input to all the peripherals connected to the signal, and affects the internal status signals.

Bit 3 – MUXPOS Positive Input MUX Selection

Writing to this bit field selects the input signal to the positive input of the AC.

Value	Name	Description
0x0	AINP0	Positive Pin 0
0x1	AINP1	Positive Pin 1

Bits 1:0 – MUXNEG[1:0] Negative Input MUX Selection

Writing to this bit field selects the input signal to the negative input of the AC.

Value	Name	Description
0x0	AINN0	Negative Pin 0
0x1	AINN1	Negative Pin 1
0x2	VREF	Voltage Reference
0x3	DAC	DAC output.
