Abstract
A sideband bus setting system in which multiple target devices (ICs) are communicably connected to a master device through a bus so as to set data to ICs mounted on an electronic device. The target device is provided with a target domain ID identifying a target domain-which is a subgroup of multiple target devices, and the master device is provided with the same target domain ID as that provided for the target device. The master device receives the target domain ID from the target device, and performs data-setting process to the target device when the target domain ID received from the target device coincides with the target domain ID provided for the master device. According to the above feature, the failure of the bus (for example, the failure of a sideband multiplexer) can be detected in advance, thereby preventing overlooking the improper data-setting operation.
