1. A method comprising: configuring via a first debug port an internal monitoring mechanism of a processing device to output first data associated with a predetermined operational state of the processing device, wherein the processing device comprises a plurality of processors and a plurality of registers associated with the plurality of processors to implement event monitoring, and wherein outputting first data comprises instructing the plurality of processors to output data via a second debug port, the data associated with an operational state that corresponds to the plurality of registers; and loading control code into the processing device, the control code executable by the processing device to output second data via the second debug port, the second data associated with input operations and exceptions that occur during execution of test code by the processing device.
