In your state machine, set the GPIO in toggle mode and insert toggle action in two states which are continously accessed in the state machine to and fro.

I tired the toggle action, but the result still can't solve my problem.
In the picture below, I make a contrast of simulation and my design (Red part).
Can GPIF-II make GPIO as fast as Clock pulse? because I need to design DDR signal.
