Abstract: The invention provides a clock select circuit and method which uses feedback arrangements between latches in different branches, with each branch for coupling an associated clock signal to the circuit output. An override circuit is provided in one of the feedback arrangements for preventing a latching delay in that feedback arrangement. This enables rapid switching between clocks in both directions.
