If the coordinates increase by 1, the position moves
by 4 horizontal pixels and 2 vertical lines.
The upper left and lower right horizontal and vertical
coordinates (1 byte each) are each divided into upper
and lower 4 bits.

Usage: Sets the mask position mainly according to the
optical.
Note:
Set the mask size to sufficiently cover the mask
object. In addition, ensure that the settings are
set on the WIDE end.
The minimum unit of the mask width is 4
horizontal pixels and the minimum unit of the
mask height is 2 vertical lines.
