Bit 7 – INVERT Invert AC Output

Writing this bit to ‘1’ enables inversion of the output of the AC. This inversion has to be taken into account when using the AC output signal as an input signal to other peripherals or parts of the system.

Bit 6 – INITVAL AC Output Initial Value

To avoid that the AC output toggles before the comparator is ready, the INITVAL can be used to set the initial state of the comparator output.

Value	Name	Description
0x0	LOW	Output initialized to ‘`0`’
0x1	HIGH	Output initialized to ‘`1`’

Bits 5:3 – MUXPOS[2:0] 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	-	Reserved
0x2	-	Reserved
0x3	AINP3	Positive Pin 3
0x4	AINP4	Positive Pin 4
Other	-	Reserved

Bits 2:0 – MUXNEG[2:0] 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	-	Reserved
0x2	AINN2	Negative Pin 2
0x3	AINN3	Negative Pin 3
0x4	DACREF	DAC Reference
Other	-	Reserved
