Color LCD Controller (CLCDC)

Cursor Image RAM Register

The CursorImage Register is read and write. It contains 256-word wide values which

are used to define the image or images overlaid by the hardware cursor mechanism. The

image must always be stored in LBBP mode (little-endian byte, big-endian pixel) mode,

as described in Image format on page 5-11. Two bits are used to encode color and

transparency for each pixel in the cursor.

Depending on the state of bit 0 in the ClcdCrsrConfig Register (see Cursor

Configuration Register on page 5-20), the cursor image RAM contains either four

32x32 cursor images, or a single 64x64 cursor.

The two colors defined for the cursor are mapped onto values from the ClcdCrsrPalette0

and ClcdCrsrPalette1 Registers (see Cursor Palette Registers on page 5-20).

Cursor Control Register

The ClcdCrsrCtrl Register is read and write. It provides access to frequently used cursor

functions, such as display on/off control for the cursor, and the cursor number for 32x32

bit cursors.

Figure 5-7 shows the register bit assignments.
