Computer systems constructed from large-scale integration circuitry have limitations or design problems relative to interfacing various control signals and data between different functional or logical areas implemented on different chips. This problem is usually the result of a limitation on the number of signal pins that are available on the chip. Generally speaking, circuitry is provided to eliminate a large number of interface signals and still provide a data transfer path for passing data between different chips. The arrangement is particularly useful in a computer system which normally has a serial data transfer capability for test purposes.
