ABSTRACT:
An electronic device operates with an external accessory by initiating a serial data communication over an accessory control bus. If data communication is established with the external accessory, the electronic device operates in a first interface mode, when one or more operating parameters are transferred over the bus. If data communication is not established, the electronic device operates in a second interface mode, when no operating parameters are transferred over the bus.
