Claim 13:
14. A system comprising:
a first physical interface circuit coupled to receive a supply voltage, wherein the first physical interface circuit includes transmitter circuitry configured to transmit a plurality of data bits;
a second physical interface circuit configured to receive the plurality of data bits transmitted by the transmitter circuitry, wherein the second physical interface circuit includes error detection circuitry configured to assert an indication in response to detecting an error in the plurality of data bits; and
an event capture circuit configured to, in a debug mode, monitor the supply voltage provided to the transmitter circuitry, and further configured to provide for debug, in response to the error detection circuit generating the indication, information indicative of a state of the supply voltage at a time the error was detected to a host computer system external to the first interface circuit.
