ABSTRACT:
A serial display drive for an electronic system including control circuitry that manipulates a serial clock signal that synchronizes each of a plurality of status bits in a serial data stream. The serial display drive circuitry includes a set of indicating elements for displaying the status information and means for switching the indicating elements. The control circuitry periodically stops the serial clock signal to provide a status update interval for each of the indicating elements and to obviate the need for a register element and strobe signal to hold data for the light-emitting elements. In another embodiment, the control circuitry generates bar graph displays.
