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 also 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.
ValueNameDescription
0 AINP0 Positive Pin 0
1 AINP1 Positive Pin 1
1 AINP2 Positive Pin 2
1 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.
ValueNameDescription
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.
