Base address of the LCD controller inside KIO region.
Different boards from XTFPGA family have LCD controller at different
addresses. Please consult prototyping user guide for your board for
the correct address. Wrong address here may lead to hardware lockup.

help
LCD may be connected with 4- or 8-bit interface, 8-bit access may
only be used with 8-bit interface. Please consult prototyping user
guide for your board for the correct interface width.
