Abstract

The present invention relates to a method for generating a clock for communication between a controller generating and outputting communication data and a device receiving the communication data from the controller, the method comprising: the controller assigning communication-clock generation command information in a communication protocol to output communication data; the communication data-receiving device counting the number of clocks generated from a built-in clock generator, while receiving the communication-clock generation command information; the device dividing the number of clocks counted by a fixed value; and the device producing a communication clock by using a resulting value from the division.  The present invention is advantageous in that communication speed related information can be assigned in a part of the communication protocol, without the use of a precision clock generator, so as to generate a communication clock in an effective way to attain accurate communication.
