48.8 Radio Arbiter

The Radio Arbiter provides a low-level arbitration for using the single RF frontend for both 802.15.4 and Bluetooth links. The arbiter supports the following modes:

• BT static – Radio ownership is with the Bluetooth link controller
• ZB static – Radio ownership is with the 802.15.4 subsystem
• Dynamic – Radio ownership is decided dynamically at every arbitration event (default mode)

At any time, it is possible to configure the Radio Arbiter in either Bluetooth or 802.15.4 static mode. In these modes, no arbitration is done and the radio is owned by either the Bluetooth Link Controller or the 802.15.4 Subsystem.
