Zusammenfassung:	The invention relates to a control circuit and a control method for an inter-integrated circuit (I2C) bus. The circuit includes an I2C master device and a plurality of I2C device groups; the I2C device groups includes I2C drive devices and a plurality of I2C slave devices; the I2C interface of the I2C master device is connected with the I2C drive devices and the IO interfaces of the I2C master device are connected with the enabling terminals of the I2C drive devices; one ends of the I2C drive devices are connected with the plurality of I2C slave devices; the I2C master device sends enabling signals to the I2C drive devices; the I2C master device sends data to the I2C drive devices in an enabling state and the I2C drive devices process data which are then sent to each of the I2C slave devices; and if the device addresses of the I2C slave devices are identical with an address code, then the I2C slave devices communicate with the I2C master device. So the control circuit and the control method for the I2C bus en
