| Enables advanced event preparation offset ahead of radio tx/rx, taking |

| This feature maximizes radio utilization in an average role event |
| timeslice when they are closely spaced by using a reduced offset |
| between preparation and radio event. |
| |
| By disabling this feature, the controller will use a constant offset |
| between the preparation and radio event. The controller will toggle |
