Bit Descriptions:

RSVD:

Reserved - Unknown during read

COLOR:

Color - Read/Write

The Color value that is written to this field specifies the
cursor image color that is inserted directly into the video
pipeline. This color overlays all other colors when the
cursor is enabled. This color does not go through the LUT.

The 2-bits-per-pixel cursor image is stored anywhere in
SDRAM. When cursor pixels are fetched from SDRAM,
they are decoded and displayed as:

00 - Transparent
01 - Invert video stream
10 - CursorColor1 during no blink; CursorBlinkColor1
during blink
11 - CursorColor2 during no blink; CursorBlinkColor2
during blink
