Six bits select the height of the cursor image. The height is measured in lines and should be
set to a value of one less then the desired number of lines.
Two bits select the cursor width:
0 0
0
1 0
1 1
Six bits are used in DUAL SCAN mode, where DUAL SCAN mode is selected by writing
DSCAN = ‘1’ to the
This register is set to the cursor color value that is used when the pixel color value is a 0x2
(10 binary).
This register is set to the cursor color value that is used when the pixel color value is a 0x3
(11 binary).
This register provides the place in the X and Y position of the image where the cursor should
be inserted. The X position is represented by the XLOC bits and the Y position is represented
by the YLOC bits in the
with the respective counter (YLOC is the line counter, XLOC is the pixel counter). These
values must fall between the active start and stop parameters for the display.
This register also contains the enable bit, CEN, for the hardware cursor. Writing a ‘1’ to this bit
enables the hardware cursor.

disabled. This line is a few pixels wide and only lasts for one frame. It is hard to catch. In
order to prevent this problem: 1. Do not enable/disable the cursor when changing the
cursor bitmaps, and 2. When disabling the cursor, change the CursorXYLOc register to
point to a blank cursor image.
