Abstract
A method and apparatus for interfacing an electronic device and an accessory is disclosed. In one embodiment the accessory comprises a communication device. To achieve desired operation of the accessory with the communication device the accessory includes memory configured to store control data or other interface data. Storing the control data in the accessory insures that the communication device has access to the control data tailored to the accessory hardware. Storing the control data on the accessory also creates independence between the accessory an the electronic device such that accessory may be introduced to market after the communication device is purchased. In one embodiment the control data is downloaded to the communication device for use by the communication device. The communication device may permanently store the control data such that the download process may be avoided during subsequent use of the accessory with the communication device.
