Abstract

A circuit includes a code sequence generator which generates a maximum length linearly occurring code sequence and which has a plurality of code data outputs coupled to respective inputs of a multiplexer, the multiplexer having an output which is coupled to an input of a three-state buffer. The output of the multiplexer and an output of the buffer are coupled to respective output terminals of the circuit. A control circuit supplies select signals to the multiplexer which cause the multiplexer to couple a selected one of its inputs to its output, and supplies to the buffer a control signal which selectively enables and disables the buffer.
