Both the user-definable 64
×
64 cursor and the crosshair cursor can be enabled for display simultaneously,
allowing the generation of custom crosshair cursors. As previously mentioned, the sprite-origin (x,y)
registers specify the 64

64 cursor pattern location relative to the cursor position and crosshair cursor.
Dual-Cursor Positioning
Figure 2–12 illustrates displaying the dual cursors, showing the relationship between the auxiliary window,
the crosshair cursor, and the 64
×
64 cursor for the case where the sprite-origin (x,y) registers are set to
(31, 31).

Figure 2–12. Dual-Cursor Positioning
Figure 2–13 shows one possible custom cursor that could be created by setting the sprite-origin registers
to (0,0) and drawing an arrow in 64

64 cursor RAM. The cursor window has been set to full screen by setting
the window-start (x,y) registers to 0000 (hex) and the window-stop registers to the last active pixel location.
The 64

64 cursor area could be located in different locations about the cursor position by programming
the sprite-origin (x,y) registers to different values as described earlier (see Section 2.3.9.3).
