Patent ID: 8140900

Claim:
An apparatus comprising: a dedicated testing and/or debugging interface to an integrated circuit; a connector connectable to a testing and/or debugging apparatus configured to communicate with the dedicated testing and/or debugging interface via the connector in a testing and/or debugging mode of the apparatus and connectable to an accessory apparatus to be used in a normal operation mode of the apparatus; and a connection circuit controllable by a controller; wherein the controller is: configured to automatically control the connection circuit to establish a connection between the dedicated testing and/or debugging interface and the connector based on an identifier received from the testing and/or debugging apparatus via the connector if the testing and/or debugging apparatus is connected to the connector, the identifier identifying the testing and/or debugging apparatus as a testing and/or debugging apparatus, thereby establishing the testing and/or debugging mode of the apparatus; and configured to automatically execute an initialization protocol, the initialization protocol being configured to initialize the accessory apparatus independently of whether the accessory apparatus or the testing and/or debugging apparatus is connected to the connector.
