    maximum frequency on a GPIO

          What is the maximum frequency for simple output     GPIOs? On the     DVK, I set the      gpio clock values to the default defined in the      FX3APIGuide.pdf pp. 232:   
           fastClkDiv = 2      slowClkDiv = 0      simpleDiv =      CY_U3P_GPIO_SIMPLE_DIV_BY_2      clkSrc =     CY_U3P_SYS_CLK.   
          There is also a sentence: "These default values must be used if only simple      GPIO is required."   
          Does this means that      GPIO cannot achieve a higher frequency?    
          The frequency I get from a pin on      DVK is around     740KHz. How can I increase this speed?
