    What is the max clock frequency that the GPIO can simulate ?

      Hi, everyone.

           I am using FX3 . Now i need use 2 GPIO pins  to simulate the serial bus , one pin is clock out and the other is data out .

           I set the GPIO as siample GPIO, and set the output value through their registers. In my test, the simulative max clock frequency is 1.03MHz.

           So What is the max clock frequency that the GPIO can simulate? I need the clock faster.

           Otherwise, Can the complex GPIO  perform faster and  simulate synchronous clock and data? I cant use other LPP ports.
