The X Location value written to this field specifies the
starting horizontal X location of the cursor image. The
value is compared to the horizontal pixel counter and it
should be specified to be between the active start and
active stop horizontal pixel values.
This X Location value is also used to specify the starting
location for the cursor image in the upper half of the
display when Dual Scan mode is enabled by writing
DSCAN = ‘1’ in the
register.
The cursor hardware will clip the cursor at the right edge of
the screen. To prevent cursor distortion, a new X Location
value will not be used until the next frame.
