Cursor
2.4.1 Cursor display
It is possible to display the cursor on the screen. It is also possible to select whether or not to display the cursor,
and when cursor display is selected, it is always displayed in the front-most screen. This LSI has a pattern register
for the display of a cursor with a size of 16 pixels
× 16 lines × 2 bits in which it is possible to write the cursor shape.
Displaying the cursor has no effect on the display memory.
The cursor display color can be specified by the contents of the 2-bit (4-value) cursor pattern register for each pixel.
One of the four values is “transparent”, and that pixel is not displayed when this value is specified. The other 3
values respectively correspond to the 8-bit cursor color registers (CSCOL1 to CSCOL3), and the specified value is
converted to the actually displayed pixel data from the color palette common to the display memory output.
2.4.2 Cursor display position
The cursor display position is specified in terms of the position in the screen of the cursor origin (the top left corner
of the cursor).
