Semiconductor integrated circuit having a plurality of processing circuits respectively executing necessary processes and a plurality of data holding circuits corresponding to the processing circuits

摘要

A control signal generating circuit for generating control signals, based on a first clock signal, a second clock signal and a mode setting signal, and a plurality of scanpath circuits. Operation of each of the scanpath circuits is controlled according to the generated control signals. The control signal generating circuit and scanpath circuits are provided in a semiconductor integrated circuit having reduced size.
