| enum ac_chan_neg_mux ac_chan_config::negative_input |
Input multiplexer selection for the comparator's negative input pin.
Any internal reference source, such as a bandgap reference voltage or the DAC, must be configured and enabled prior to its use as a comparator input.

Output mode of the comparator, whether it should be available for internal use, or asynchronously/synchronously linked to a general-purpose input/output (GPIO) pin.

Sampling mode of the comparator channel.

| uint8_t ac_chan_config::vcc_scale_factor |
Scaled VCC voltage division factor for the channel, when a comparator pin is connected to the VCC voltage scalar input.
The formular is: Vscale = Vdd * vcc_scale_factor / 64. If the VCC voltage scalar is not selected as a comparator channel pin's input, this value will be ignored.
