Abstract
The control apparatus reads the value of an external switch, and checks whether the apparatus serves as a control side or subordinate side. If the control apparatus serves as a subordinate side, it waits until the control side writes a configuration through a bus. If the control apparatus serves as a control side, it sets necessary values in itself, and writes a configuration in a device on the bus. In this way, the control apparatus can operate as both the control side and subordinate side.
