Need 16Mhz frequency on jetson nano GPIO pin

I am trying to achive 16Mhz frequency on jetson nano GPIO pin. I saw this code on github(GitHub - jwatte/jetson-gpio-example: Simple example of memory-mapped NVIDIA Jetson GPIO access from user space C code) where we can access directly GPIO from kernel. I am completely new on Jetso nano board so I don’t understand what pin they used in code to toggle LED on nanosecond delay with high frequncy. Anyone can help me to understand this code. What GPIO pin I have to use to achive 16Mhz frequnecy?

hello rxuser,

for your reference,
there’s a Python library, Jetson GPIO that enables the use of Jetson’s GPIOs.
thanks
