Summary:A method and apparatus for observing the contents on internal memory-mapped registers of controllers and co-processors which have been integrated on-chip with a central processing unit ("CPU"). The CPU asserts a first signal when access to internal memory is requested and deactivates a second signal which would normally allow simultaneous access to both internal and external memory locations. In this way, the contents of internal memory may be observed in real time.
