Abstract: A system on chip includes a display serial interface (DSI) host device, a camera serial interface (CSI) host device, a first register, and a loopback control circuit. The first register is configured to store a first flag indicating whether the system on chip is operating in a loopback mode or a non-loopback mode. The loopback control circuit is configured to loop back data generated by the DSI host device to the CSI host device in response to the first flag indicating that the system on chip is operating in the loopback mode.
