Color LCD Controller (CLCDC)

Table 5-5 lists the register bit assignments.

If CrsrFrameSync is 0, the cursor position changes immediately, even if the cursor is

currently being scanned.

If CrsrFramesync is 1, the cursor position is only changed during the next vertical frame

blanking period.

Cursor Clip Position Register

The ClcdCrsrClip Register is read and write. It defines the distance from the top-left

edge of the cursor image, to the first displayed pixel in the cursor image.

Figure 5-11 shows the register bit assignments.
