<p>A logic circuit part (10), which is composed of a flip-flop group (11) and a combinational circuit (12) and performs a sequential logic operation, is added with a specify circuit (22) for selectively specifying desired flip-flop circuits (FC) in the flip-flop group and a write circuit (21) for applying a set or reset signal to the flip-flop circuits selectively specified by the specify circuit. Each flip-flop circuit includes: a flip-flop for writing input data in response to a system clock (Csy); a first AND gate which, when the flip-flop circuit is selectively specified by the specify circuit, passes therethrough the set signal to set the flip-flop; a second AND gate which, when the flip-flop circuit is selectively specified by the specify circuit, passes therethrough the reset signal to reset the flip-flop; and a third AND gate which, when the flip-flop circuit is selectively specified by the specify circuit, passes therethrough the output logic (Sout) of the flip-flop to the outside. <IMAGE></p> |
