Hardware cursor

hardware cursors is specified as a 64 × 64-pixel area. Each pixel of these
hardware cursors is 8 bits and uses the indirect mode look-up table.
1.5.3 Frame Control
Double buffer scheme
This mode provides smooth animation. The display frame and drawing frame
are switched back and forth at each scan frame. A program in the vertical
blanking period controls flipping.
Scroll scheme
Wrap around scrolling can be done by setting the drawing area, display area,
display size and start address independently.
Windows display
The whole screen can be split into two vertically separate windows. Both
windows can be controlled independently.
