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.
Example) Setting the mask position according to the
following parameters during NTSC
Mask Number 1
