Toggling GPIO port

Other Parts Discussed in Thread: TMS320C28346

Hi,

I'm working with a TMS320C28346 microcontroller at 300Mhz, and I was testing the maximum speed that I can toggle a GPIO pin, right now I was just able to produce a 300kHz output frequency.

Is there any kind a limitation for using this method? What is the maximum speed that you can get?

Thanks for your help,

Paul Vicioso.
