23.7.5.2 Cursor sizes
23.7.5.3 Cursor movement
23.7.5.4 Cursor XY positioning
When the display point is inside the bounds of the cursor image, the cursor replaces
frame buffer pixels with cursor pixels.
When the last cursor pixel is displayed, an interrupt is generated that software can use as
an indication that it is safe to modify the cursor image. This enables software controlled
animations to be performed without flickering for frame synchronized cursors.
Two cursor sizes are supported, as shown in
Table 488. Palette data storage for STN monochrome mode.
The following descriptions assume that both the screen and cursor origins are at the top
left of the visible screen (the first visible pixel scanned each frame).
each pixel coordinate is assumed to be the top left corner of the pixel.
The CRSR_XY register controls the cursor position on the cursor overlay (see Cursor XY
Position register). This provides separate fields for X and Y ordinates.
The CRSR_CFG register (see Cursor Configuration register) provides a FrameSync bit
controlling the visible behavior of the cursor.
