Abstract

During the testing and debugging of a microprocessor-based system, it is useful to connect the system to a controller or processor. The adapter shown in the drawing allows the interrogation of memory and microprocess registers to be performed mainly by the controller rather than relying too heavily on the microprocessor itself. Thus, nearly all the address space of the microprocessor can be used as intended with little space being reserved for the test.
