Table D-2:
The meaning of the single bit in a given pixel position in the XOR plane changes depending on the bit in the
corresponding position in the AND plane. If the value of the bit for a given pixel position in the AND plane
is 0, then part of the cursor will be displayed at that pixel position and the value of the corresponding bit in
the XOR plane selects one of the two available cursor colors to be displayed there. Otherwise if the value
of the bit in the AND plane is 1, then that pixel position of the cursor will become transparent, allowing a
pixel of the main display image behind the cursor to show through and the value of the corresponding bit in
the XOR plane chooses whether or not the color of the pixel of the main display image will be inverted.
Table D-3 summarizes this.
