ABSTRACT:
Mode detection circuitry includes first detection circuitry which detects the presence of a first input signal selectively presented at a first terminal for a first selected time duration and, in response, selectively generating a first control signal indicative of a first mode. Second detection circuitry detects the presence of a second input signal selectively presented at a second terminal for a second selected time duration and, in response, selectively generating a second control signal indicative of a second mode. Control circuitry configures the second terminal as an output terminal in the first mode and as an input terminal in the second mode in response to the first and second control signals.
