2 Notes
2.1 Busy Ctrl Line
Used to indicate the status of the internal state machine.
The amount of time the BUSY line is stay HIGH.
When the BUSY line is held low, it indicates that the internal state machine is in idle mode and that the radio is ready to accept a command from the host controller.
The BUSY line is set back to zero once the chip has reached a stable mode and it's ready for a new command
