An I2C/SPI control interface circuitry, an integrated circuit structure, and a bus structure thereof are provided. The I2C/SPI control interface circuitry includes an I2C control module and a SPI control module. The I2C control module has an I2C clock port and an I2C data port, and the SPI control module has a SPI clock port, a SPI data input port, a SPI data output port, and a SPI chip enable port. The I2C clock port is electrically connected with the SPI chip enable port to become an I2C clock/SPI chip enable input/output end. The I2C data port is electrically connected with the SPI data input port and the SPI data output port to become an I2C/SPI data input/output end. The SPI clock port is the SPI clock output end. The I2C and SPI control module are alternative to be enabled to avoid signal interference and lower the cost of the package and the manufacture of the integrated circuit.
