  • Accessory interface for a portable communication device
    Patent number: 11238002
    Abstract: An accessory interface (100) for an electronic accessory is provided. The accessory interface includes a microprocessor (102) that provides selectable data functionality. A configuration memory (106) is coupled to a connector (104) of the accessory interface via a unidirectional configuration interface (108). The unidirectional configuration interface indicates the selectable data functionality to a portable radio. The portable radio presents data connectivity signals to first and second GPIO pins of the connector which represent either valid or invalid data configuration states. The configuration state is presented to a single ended one (SE1) input port of the microprocessor. The microprocessor selects a data connectivity mode of operation in response to valid and invalid configurations being presented to the SE1 port. An accessory incorporating the accessory interface is able to interchangeably connect to different radios supporting different data connectivity modes of operation.
