In standard mode, STC0 is the only cursor tile code register that is enabled. Use
the cursor horizontal position register (SHP, x’00F12’) and the cursor vertical
position register (SVP, x’007F14’) in both modes to program the display start
position. In extended mode, this position refers to the upper left corner of tile (1).
Set the color palette for each tile individually.
7.6.2 Graphics Layer Display Modes
The size of the tiles in the graphics layer is programmable to 16W x 16H pixels
in standard mode and 16W x 18H pixels in extended mode. Select the mode for
this layer in the GTHT bit of the OSD2 register (x’007F08’).
You cannot use the tiles created
for graphics layer extended
mode as cursor tiles.
In extended mode, the tiles are the same size as the characters in the text layer.
This allows for a cleaner display when text and graphics appear side by side.
