1. Logic element circuitry comprising: selection circuitry for using a first selection circuit input signal to select a second selection circuit input signal or a third selection circuit input signal as a selection circuit output signal; logic circuitry for providing a logic circuit output signal, wherein said logic circuit output signal is a logical function of first and second logic circuit input signals; and a first programmable interconnection circuitry configured to couple a signal from a group consisting of the selection circuit output signal and a signal from outside the logic element to at least one of the first and second logic circuit input signals.
