According to the manual, the I/O ports addresses:
Exx9
ExxC
ExxD
ExxE
ExxF
are unused. How can I used these ports as general purpose I/O. I can decode the address bits and PE7 to generate a chip select signal, but I do not have a /IOR or /IOW function. Are the LCD ports write only?
Any help greatly appreciated.
