Semiconductor integrated circuit has a control circuit. The control circuit causes the clock signal generating circuit to control the first clock signal and the second clock signal to make a logic of data held by the first data holding terminal and a logic of data held by the second data holding terminal equal to each other, and switches on the switch circuit, and the error detection circuit senses a logic of the first data holding terminal and a logic of the second data holding terminal after switching on the switching circuit.
