ABSTRACT:
A logic module uses a multiplexer which can be used to configure the logic module as combinational or sequential. A sequential block comprises a flip-flop with preset and clear, and can be SR or D-type. The multiplexer is used in the feedback loop of the flip-flop, thus by choosing an appropriate select signal the feedback can be connected/disconnected.
