A semiconductor chip transmits a request signal which requests notification of the setting state of a chip identifier to another semiconductor chip connected to one of the upstream and downstream, receives a response signal indicating the setting state of the chip identifier and the value of the chip identifier, as a response to the request signal, and performs a chip identifier setting process based on the response signal. When receiving a request signal from another semiconductor chip connected to the other of the upstream and downstream, the semiconductor chip transmits a response signal indicating the setting state of the chip identifier and the value of the chip identifier, as a response to the request signal. |
