Abstract
A processor for outputting processor state information during idle bus cycles to facilitate the diagnosing and debugging of a processor. The processor includes a plurality of external pins for communicating data from the processor; a visibility register for selecting one of a plurality of modes which identifies processor state information to output onto the plurality of external pins; and a bus interface unit for communicating data to the external pins of the processor and for detecting an idle bus cycle. The bus interface unit outputs processor state information according to the identified mode onto the plurality of external pins in response to detecting an idle bus cycle.
