2 cursor RAM provides two bits of cursor information on every pixel clock (dot clock) cycle
during the 64

64 cursor window. Cursor-control-register bit 4 specifies whether the XGA mode
(default = logic 0) or X-window mode (logic 1) standard is used to interpret the cursor information. The two
bits of cursor pixel data determine the cursor appearance as shown in the table below:

64 Cursor Positioning
The cursor-position (X and Y) registers are used in conjunction with the sprite-origin (X and Y) registers to
position the 64
×
64 cursor on the display screen. The cursor-position (X and Y) registers specify the location
of the cursor on the display screen relative to the first displayed pixel out of blank. The sprite-origin (X and
Y) register specifies where to origin the 64
×
64 cursor array relative to the cursor position (X and Y). Upon
reset, the sprite-origin (X and Y) register automatically defaults to (31, 31). Therefore, the cursor-position
(X and Y) registers specify the location on the active display screen of the 31st column and 31st row
(counting from top left) of the 64
×
64 cursor array. The crosshair cursor intersects at the center of the sprite
cursor area.
2.5.3
The sprite-origin (X and Y) registers can be programmed from (0,0) to (63,63). For example, if the
sprite-origin (X and Y) registers were programmed to (0,0), the 64
×
64 cursor array would be located in the
lower right quadrant with respect to the cursor position (x,y). Figure 2–7 illustrates this more clearly by
showing the 64
×
64 cursor array location relative to the cursor position (x) for different sprite-origin values.
