128x128x1bpp 1-Color and Transparency Mode
This mode provides one color for drawing the cursor and a second color for transparency (which allows the
image behind the cursor to show through).
In this mode, it is possible to have only up to 2 different 2KB patterns stored in a 4KB memory space starting
at the base address specified in the low and high base address registers for the given cursor.
The following tables show how the cursor data is organized in memory and the meaning of the bit for each
position.
