Various controls of display are set up.
(1) REF Command
When MPU accesses to the graphic display
RAM, the relationship between X address and
write data is normalized or reversed.
Therefore, the order of segment drive output
can be reversed by register setting, to lessen
the limitation on placing IC when composing an
LCD module.
