Does the w/a thing actually work correctly for masked registers?
It look to use rmw even for masked registers and IIRC some masked
registers return 0xffff for the mask when read. I lost track of the
values and masks being passed around before I got down that deep so
can't immediatly see if the code is guaranteed to set only the
expected mask bit(s) for the write.
