1.6.2.1 Struct ac_chan_config
Configuration structure for a comparator channel, to configure the input and output settings of the comparator.
| Type | Name | Description |
|---|---|---|
| bool | enable_hysteresis |
When true, hysteresis mode is enabled on the comparator inputs |
| enum ac_chan_filter | filter |
Filtering mode for the comparator output, when the comparator is used in a supported mode |
| enum ac_hysteresis_level | hysteresis_level |
Hysteresis level of the comparator channel |
| enum ac_chan_interrupt_selection | interrupt_selection |
Interrupt criteria for the comparator channel, to select the condition that will trigger a callback |
| enum ac_chan_neg_mux | 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. |
| enum ac_chan_output | output_mode |
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 |
| enum ac_chan_pos_mux | positive_input |
Input multiplexer selection for the comparator's positive input pin |
| bool | run_in_standby |
If true, the comparator will continue to sample during sleep mode when triggered |
| enum ac_chan_sample_mode | sample_mode |
Sampling mode of the comparator channel |
| uint8_t | 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. |
