Abstract
Described is a sequencing device comprising a plurality of shift register stages, a plurality of switches and an output bus which couples the outputs from the shift register stages to inputs of the switches. Each shift register stage includes a data input port coupled to a selected switch, a clock input port coupled to a clock control signal line and a clear input port coupled to a clear control signal line. The sequencing device may be set in at least one of a plurality of states by external events that are provided as input signals to the sequencing device through input bus (10).
