Claim 5:
6. A data transmission and reception method of a data processing device comprising:
configuring an environment for a high-speed communication with a data driving device by performing a low-speed communication with the data driving device, the high-speed communication having a clock frequency higher than that of the low-speed communication;
storing an initial configuration value regarding the environment for the high-speed communication;
transmitting the initial configuration value to the data driving device after having transmitted a clock pattern indicating a communication clock for the data driving device; and
periodically transmitting image data to the data driving device by the high-speed communication,
wherein the performing the clock training includes transmitting a first status signal indicating completion of the clock training and, when any abnormality is detected in the high-speed communication in restoring a configuration of the environment, transmitting a second status signal changed from the first status signal to the data processing device.
