Title (EN) A METHOD AND APPARATUS FOR INTERFACING AN ELECTRONIC DEVICE WITH AN EXTERNAL ACCESSORY
(FR) PROCEDE ET APPAREIL SERVANT D'INTERFACE ENTRE UN DISPOSITIF ELECTRONIQUE ET UN ACCESSOIRE EXTERNE
Abstract:
(EN) 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.
(FR) Un appareil électronique fonctionne avec un accessoire externe par lancement d'une communication de données en série sur un bus de commande de cet accessoire. Si la communication avec l'accessoire externe est établie, le dispositif électronique fonctionne dans un premier mode interface, lorsqu'au moins un paramètre de fonctionnement est transféré sur le bus. Si la communication de données n'est pas établie, le dispositif électronique fonctionne dans un second mode interface lorsqu'aucun paramètre de fonctionnement n'est transféré sur le bus.
