CONTROLLER FOR AUTOMATICALLY CONTROLLING TIMING SPECIFICATION AND THE TIMING SPECIFICATION CONTROLLING METHOD THEREOF

摘要

will automatically control the timing specification controllers and their timing specification control method is disclosed. The controller is based on a counter for counting the main clock , if the counter is counting the half of the set value for generating a control signal FSM (Finite State Machine), the generated control signal in accordance with the set value of the number to be included in one main clock period (v) a synchronization clock for generating a synchronous clock generating section , and generates a control data generator for generating a data signal in accordance with the valid data based on the determined edge . As a result , the burden on the central processing unit by the controller using only the software controllable register , as well as a minimum be reduced , to secure a margin for correct setting time and hold time by the timing control by the communication is stabilized .
