Abstract: An input-output circuit is coupled to a plurality of serial communication paths and to a physical point-to-point interface. The input-output circuit is configured to transmit data received on the plurality of serial communication paths over the physical point-to-point interface. An application circuit is coupled to the input-output circuit and is configured to communicate via a first one of the paths in performing application functions. A bridge circuit is coupled to the input-output circuit and is configured to communicate via a second one of the paths. A debug circuit is coupled to the application circuit and to the bridge circuit. The debug circuit is configured to capture debug data of the application circuit and provide the debug data to the bridge circuit for communication via the second one of the paths.
