I am using a DS89C420.I want to connect one of its ports (for example port 0) to PCMCIA bus of my computer. Namely I want the controller to communicate in a parallel way to increase speed of communication.What should I do to achieve this? I mean what kind of interface should I use between the controller and PCMCIA bus and in which mode should I use the microcontroller? Could you offer a method for this? I will be happy if you give the name of the possible interface circuits.
