How to overturn a character in right and left.
4-dot data is transfered as a unit, from ROM to
VRAM or VRAM to VRAM. ROM is composed of 8
bits.
In case of "Increment x" is effective, 8-bit data is
transfered as shown below.

Position of all specified dots, maximun 256, is
overturned with right and left in horizontal. The
heart of their X coordinates becomes an axis of
symmetry.
On the other hand, in case of "Decrement x" is
effective, 8-bit data is transferred as shown below.
In each 4-dot data is automatically swapped in right
and left.
