A semiconductor device, which is daisy-chain connected with other semiconductor devices, includes a first communication section that receives reception data; a determining section that determines a type of the reception data, and that outputs a first and a second control signal according to the determination; a setting processing section that sets an address value based on the reception data and the second control signal, and that outputs a third control signal according to the setting of the address value; and a second communication section that includes a first input terminal to which the reception data is input, and an output terminal to which a communication line, that transmits transmission data to the other semiconductor devices, is connected, and that causes the first input terminal and the output terminal to be in connected or non-connected state based on the first or the third control signal.
