Abstract
A controllerhas an I/O crossover switching network, an optional I/O network expansion, a plurality of serial I/O shifters, a clock generatorand I/O control logic. The I/O crossover-switching networkis also referred to as an I/O multiplexer. Serial data may be transferred between a serial I/O shifter and an external device by way of a dedicated serial data pin (SDATA)or an optional alternate pathwaywhich uses one of a plurality of parallel pins. The optional alternate pathwaycan be used when pinsare unavailable or to reduce the number of pins on the device. The controller is shown to communicate with an external devicealso having parallel pins. While a single deviceis shown, the external devicecan be any number of a plurality of devices having serial and parallel signal pathways that is controlled by the microprocessorof the present invention.
