Abstract
There is provided a logic circuit formed of a flip-flop receiving an input data, a control signal, a set signal and a reset signal and producing an output signal and an inverted output signal. To this is added a first logic circuit performing a first logical arithmetic of the input data and the set signal to produce a first logic signal, and a second logic circuit performing a second logical arithmetic of the control signal and the reset signal to produce a second logic signal. A first selector circuit selects one of the first logic signal and the output signal and a second selector circuit selects one of the second logic signal and the inverted output signal thereby providing convesability between sequential and combination modes of operation.
