The SA-1100 microprocessor evaluation platform is neither a "typical" system nor is it a "reference design." This evaluation platform is a Design Verification Platform for the SA-1100 microprocessor. Designers of SA-1100-based systems should be able to extract the portions of the SA-1100 microprocessor evaluation platform schematics that are relevant to their particular set of design goals.
The SA-1100 microprocessor evaluation platform was designed to allow the SA-1100 to operate in as many modes as possible, and to provide hardware for "lab debug" assist. This evaluation platform assumes that the first SA-1100 being inserted into it is nonfunctional, and could possibly be damaging to other hardware in the system.
