A semiconductor integrated circuit includes a sequential circuit including a plurality of flip-flops which latch and keep data supplied to an input terminal at a prescribed timing and which perform prescribed sequential treatments of the input data, and a combinational circuit implemented at the input and/or output terminals of the sequential circuit and which performs a prescribed combinational treatment or treatments of the input and/or output data to and/or from the sequential circuit. The semiconductor integrated circuit also includes a data-through circuit operated by an external control signal configured to transfer the data supplied to the input terminal direct to an output terminal of a prescribed flip-flop of the plurality flip-flops constituting the sequential circuit. |
