Abstract

See full text

An apparatus and method for exchanging information between printed circuit board assemblies of the present invention are disclosed. According to the invention, the number of address pins are assigned according to the amount of information to be exchanged between the boards. In a preferred embodiment, where data is transferred in 8 bit words, the amount of data that can be transferred using an address bits is given by 8.times.2.sup.n. Thus, more status information can be exchanged with fewer edge pins. The duplication function between boards can so be more effectively implemented.
