D-8
128x128x1bpp 2-Color Mode
This mode provides two colors for drawing the cursor. There is no provision for transparency in the 128x128
pixel space occupied by the cursor so unless the image behind the cursor happens to be the same color as
one of the two colors used to draw the cursor, the cursor will appear as a 128x128 pixel square.
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.
