Abstract
An integrated circuit having a normal mode for operating under normal operating conditions and a debug mode for operating to test and debug the integrated circuit. The integrated circuit includes a plurality of output pins that carry a first plurality of signals in the normal mode and carry a second plurality of signals in the debug mode. In one embodiment, the integrated circuit embodies a microprocessor. The microprocessor may include logic circuitry for enabling the second plurality of signals to be output from a multiplexer to the output pins in response to a predetermined event, such as a hit in an associated memory unit.
