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.
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,
