Exclusive-OR is carried out between the current image data and the
image data one line previous. Only the changed bit is set to ON (1). The
alignment of dots is MSD (left dots) and LSB (right dots).
buffer size (512 KB) is drawn. The minimum unit of the data drawing is 8 dots (1
byte). If the graphic width is set to 3 dots, it will be reset to 8 dots (1 byte).
