For a project I’am using the RCM4300. And I have a question about it.
What I try to make is a program for a LCD-display. The display uses 3 control and 8 data signals. For the control signals I use port A and for the data signals port B.
I have some problem with port B. How can I set port B for this function? I treid, but I cannot set or reset PB0. I witten someting about auxiliary I/O bus but I do not know how to set it and control it.
