/* BMLL */
==== BMLL ====
* If source and destination ranges overlap then there can be some unexpected data written. You should avoid overlapped areas or keep them at least 2 bytes apart. Result of overlapping areas can differ between runs. Investigation is going on to determine how this data can be stablisedpredicted or forced.
* When DIX=0, then both source and destination vram addresses are incremented. When DIX=1, then both source and destination vram addresses are decremented.
* I can't currently see what DIY does in respect of BMLL. It seems it has no effect. This may be an error in the documentation.
