Hello,
I want to know whether there is any delay coming with the GPIO Pin_Write function. As per pins datasheet, rising and falling times for fast mode is 12 ns each. This is for strong drive modes. I am interested in resistivee pull up/ down mode, and has configured slew rate to be fast. Is the delay I expect should be around 24 ns?

   

Any clue on this is appreciated.

   

Thanks.

The pullup R's range from 3.5 to 8.5K in value, standard RC

   

rise time will apply for a given bus loading. Note there is a

   

toggle rate issue that can be improved with register writes,
