Here is an example about relation between RAIL_SetStateTiming setting and scheduled TX:
If you scheduled a transmit to occur on absolute time 1000µs and have an idleToTx time of 100µs and have a ramp time of 30µs:
1. Scheduled transmit should start at absolute time 1000µs.
2. IdleToTx is then in effect. The PA ramp will start at absolute time 1100µs.
3. PA ramps. Modulation starts when ramp ends (at 1130µs in this case).
