This block contains the MMIO registers for the drawing engine.
This block synchronizes and FIFOs data from the internal MMIO bus. Host data and
patterns pass through this block as well as register operations.
Monochrome bitmaps, fonts, and patterns pass through this block and are expanded
to the appropriate full color depth. The color expanded data will then be sent to the
rotator block for alignment or loaded into the Pattern RAM. Full color data also passes
through this block and is combined from
host is converted to the appropriate format by this block.
