1. A display driving device comprising:
a first communication circuit configured to receive data that sets a circuit part for a second communication mode using a higher communication frequency than a first communication mode, from a display data transmitting device, and output a first level of a first communication status signal, in the first communication mode;
a second communication circuit configured to perform a second clock training, using a clock signal received from the display data transmitting device in the second communication mode, and output a second communication status signal based on a result of the clock training, wherein the second communication circuit is activated after the first communication mode is completed; and
a third communication circuit configured to generate a status signal based on the first communication status signal and the second communication status signal, and transmit the status signal to the data transmitting device.
