摘要

It is an object of the present invention to provide a semiconductor integrated circuit that can change the pulse width of a reset signal for initializing the latch output, in which the pulse width of the reset signal is made wider during the verification process and narrower during the normal use. A semiconductor integrated circuit has a reset signal generation circuit that generates a reset signal having a reset period based on a power-on reset signal, and a latch circuit having an initialization circuit that initializes a latch output based on the reset signal. The reset signal generation circuit has a delay circuit that can variably set a pulse width corresponding to the reset period of the reset signal. An output line of the delay circuit is connected to a first pad terminal. An output line of the initialization circuit is connected to a second pad terminal. When the semiconductor integrated circuit is verified, the first and second pad terminals are brought in contact with a probe. During this verification process, according to input/output loads of a tester that is connected to the first pad terminal, the pulse width of the reset signal is set wider than that during the normal use when the pad terminals are not contacted with a probe.
