Hybrid bus communication circuit

A wireless device comprising a hybrid bus communication circuit, the hybrid bus communication circuit comprises:

• a first type communication bus comprising multiple wires and configured to carry timing critical information;
• a second type communication bus and a third type communication bus each consisting of a single wire and having a slower data rate than the first type communication bus, wherein the second type communication bus is configured to carry timing constrained information less time-sensitive than the timing critical information and the third type communication bus is configured to carry non-timing critical information less time-sensitive than the timing constrained information;
• a master circuit coupled exclusively to the first type communication bus;
• a hybrid bridge circuit coupled to the first type communication bus, the second type communication bus, and the third type communication bus;
• a plurality of multi-bus slave circuits each coupled to the master circuit via the first type communication bus and coupled to the hybrid bridge circuit via the second type communication bus;
• a plurality of single-bus slave circuits coupled to the hybrid bridge circuit via the third type communication bus;
• and
• wherein the hybrid bridge circuit and each of the plurality of multi-bus slave circuits can initiate communication over the second type communication bus via a bus contention mechanism and the hybrid bridge circuit is configured to:
• receive a configuration command from the master circuit via the first type communication bus;
• determine one or more configuration parameters based on the received configuration command;
• and
• configure the determined one or more configuration parameters in at least one selected multi-bus slave circuit among the plurality of multi-bus slave circuits via the second type communication bus.
