Abstract: A process incudes generating, by a canary circuit of a semiconductor package, an output value. The semiconductor package includes a hardware root-of-trust engine for an electronic system. The process includes comparing, by the canary circuit, the output value to an expected value. The process incudes, responsive to a result of the comparison, regulating, by the semiconductor package, a response of the electronic system to a reset request.

Abstract: A process includes controlling a current source to cause the current source to provide a plurality of different currents at different times to an output communication line of a video display interface; and acquiring a plurality of voltages corresponding to the plurality of different currents. Acquiring the plurality of voltages includes sampling a voltage of the output communication line. The process includes comparing the plurality of voltages to a plurality of voltage thresholds; and based on a result of the comparison, determining whether the video display interface is coupled to a cable-based far end termination.
