PRU frequency = 333.333.333 ( 3 ns per cycle )
PRU_PIN_0 = OUTPUT_MODE
PRU_PIN_1 = INPUT_MODE
PRU_PIN_0 and PRU_PIN_1 are connected with jumper wire.
When I write high to pin_0 , I can see the high value at pin_1 after 7 clock cycles ( 21 ns) . It means read delay + write delay = [18-21] ns. I shared my code and debug status. My project is very time critical. That's why I need to learn what pin toggling delay and pin read delay are. maybe pin toggling delay is 5 ns, reading 15 ns, maybe otherwise , maybe both of them 10 ns. I need to learn delay of each step. I researched a lot but I could not find a document which gives these values. Every document says "low latency", nothing more.
