First, if you want to connect the display as MMIO, you naturally have to add an address
decoder to your display. I wonder whether it is some space in PLD to fit it in.
As I don't have the original Ethernut board, neither have I studied it, I do not know.

This is the siple part, just use a pointer directed to correct address e.g.

unsigned char *display=0xf123;
*display=0x12;
