Claim 0:
1. A data transmission and reception method of a data driving device comprising:
configuring an environment for a high-speed communication with a data processing device by performing a low-speed communication with the data processing device, the low-speed communication having a clock frequency lower than that of the high-speed communication;
receiving a clock pattern from the data processing device and performing a clock training;
storing an initial configuration value as a configuration restoration value after having received the initial configuration value regarding the environment for a high-speed communication from the data processing device; and
restoring the environment for a high-speed communication according to the configuration restoration value when any abnormality is detected in the high-speed communication while periodically receiving image data from the data processing device by the high-speed communication and processing the image data,
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.
