| type: boolean |
| description: | |
| Disables an undocumented compare feature (sets COMP_CxCSR bit #1 to 0) which |
| holds the comparator output during the duration of the Miller effect. |
| NOTE: This setting is supported only by stm32g4x series. |
| NOTE: It is recommended to enable the feature unless very fast events are tracked. |
