Semiconductor integrated circuit device having flip-flops that can be reset easily

摘要

A semiconductor integrated circuit device includes a plurality of flip-flops, each of which has an external input terminal and external output terminal, the flip-flops being cascade-connected by having data output terminals respectively connected to data input terminals of the next-stage flip-flops. A reset signal is input via the external input terminal of the first-stage flip-flop and is sequentially transferred from the external output terminal thereof to the next-stage flip-flops. The reset signal is transferred via a transmission path different from the original data transmission path to reset all of the flip-flops.
