Abstract
A circuit for controlling flip-flop hold and set-scan operations responds to one state of a HOLD/PASS signal by blocking the provision of a flip-flop CLOCK signal to one or more flip-flops which are to conduct a holding operation. The circuit responds to the pass state of the HOLD/PASS signal by permitting the flip-flop clock to be provided to the control flip-flops so that they can conduct shift or pass operations.
