Abstract

Pin-count or wire quantity sometimes prove to be a limiting factor in a design. The circuitry presented here can allow for reduced count of these things by allowing pins or wires to operate in a full-duplex mode. The cir- cuitry can be built of discrete components; however, it is intended to reside on a single chip and is illustrated this way in Figure I. If the circuitry were built discretely, the savings would be a reduction of communication wires between devices, but at the cost of many extra parts. Inte- gration of the circuitry within the chip allows for both (I) reduced wire interconnects between devices with this cir- dry and (2) reduced pin count on parts with this circuitry.
