I have some problem in controlling Analog & Digital Control Port. I want to use these ports by 8-bit binary combimation. But, they don't activate simultaneously. I think each port has some latency. Consequently external device connected to these control ports would recognize different signal I didn't send to that. I want these ports to turn "on" at time. How fast could these ports change to another state? Is there any way to make these ports act simultaneously?
