PURPOSE: A system for controlling a device of a processor is provided to detect an error generating source by controlling a plurality of devices by connecting the devices using a personal data line. CONSTITUTION: A processor(300) generates data controlling a device in a control data creating unit(301), and transmits the data to a switching device(320) through an input/output bus interface unit(303). An internal data processing unit(302) of the processor(300) receives data transmitted from the switching device(320) through the input/output bus interface unit(303) and processes the data. Because address for information an ID of a specific device is included in a bus transmitted from the processor(300), an ID comparator(321) of the switching device(320) can perceive the specific device to be controlled by the processor(300). A switching unit(322) of the switching device(320) switches a path by the specific device, and transmits data transmitted from the processor(300) through the separated data line. If the specific device is a device_1(310_1), the device_1(310_1) receives data from the switching device(320) and generates a signal indicating a signal for completing a preparation for receiving a control data from a RDY creating unit(313). Thus, the generated signal is transmitted to the switching device(320), and the signal is transmits from a RDY transmitting unit(323) of the switching device(320) to the processor(300). Therefore, the processor(300) transmits a device control data.
