ABSTRACT:
A programmable n stage shift counter divider circuit includes a plurality of n flip-flops arranged in cascade from a first stage to an nth stage. The data inputs of each of the flip flops are coupled with the output of the next preceding stage through corresponding OR gates. A source of preload signals is coupled with the second inputs of the OR gates; and a combined trap detector and terminal count detector has inputs coupled with the outputs of the last n-1 stages of the shift counter circuit and an output coupled with the source of pre-load signals to operate it.
