ABSTRACT:
The present invention involves a configurable flip flop having a first data input node, a second data input node, and an output node. The configurable flip-flop includes an inverter coupled to the first data input node. Each of a plurality of configuration lines address a multiplexor and the flip-flop output node for selecting one of the first data input node, the second data input node, or an inverted first data input and coupling the selected one to a multiplexor output A latch receives the multiplexor output and generates a gated output and an edge triggered output. A configuration bit controlled selector couples either the gated output or the edge triggered output to the configurable flip-flop output node.
