Abstract

A programmable interface to selectively couple the terminals of an electronic system to desired circuit locations within the system. By applying programming signals to the input terminals of the interface in a prescribed sequence, the interface is programmed so that subsequently applied control signals will be coupled to the desired circuit locations. The function served by each terminal thus depends on the programming sequence. Reprogramming can change the function of each of the terminals by coupling them to different circuit locations.
