I am using RCM2200 module for my project. In that project i am facing problems with interfacing of graphic display(TM12864A2FFWg-B).

I have one doubt in the interfacing of this GLCD.Actually the data can be send through parallel/serial by setting P/S pin as HIGH or LOW.but it was not give the pin to outside.How can i set it.

kindly give a solution for it.
