  • Patent number: 10347170
    Abstract: A method of recovering an error in data communication according to an exemplary embodiment of the present inventive concept includes performing data communication between a first device and a second device through a data line and a clock line; detecting a communication error in the data communication when the first device is in an output mode; and in response to the detecting, outputting, by the second device, a stop signal to the data line repeatedly until the first device is in an input mode. According to exemplary embodiments, if a device stays in an output mode due to a communication error, a stop signal is repeatedly output to the device until the device switches to an input mode, whereupon the communication error can be recovered from. Thus, quality of data communication can be improved.
