Assuming that the 3-bit input pattern that represents this 33% duty cycle grayscale is 0x2 or
010b, the values in
table. In this mode, the X locations are ignored by the grayscale generation.
The raster engine provides support for a hardware cursor. The hardware cursor has a
separate bus mastering interface that allows it’s image to be stored anywhere in memory.
Software provides a location start, reset, size, X and Y position, and two cursor colors. The
hardware loads a line at a time from memory and multiplexes the video stream data based on
the cursor values. The X and Y locations are compared to the horizontal and vertical counters
and trigger the state machine to enable the cursor output overlay.
