Bit 7 – INVERT: Invert AC Output

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.

Bits 4:3 – MUXPOS[1:0]: Positive Input MUX Selection

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
0x2	AINP2	Positive Pin 2
0x3	AINP3	Positive Pin 3

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

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 Instance n of the AC will use instance n of the DAC: for example AC0 will use DAC0 and AC1 will use DAC1.
