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 MSB (left dots) and LSB (right dots).
* The graphic width for only the smaller value of either the designated value or the max. 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).
