Swap these bits, the first case is an acknowledgement of receiving a
command the second case is a status bit from carrying out the command.
Either way it seems a bit mindless to just or back in whatever bit you
read back here... in fact shouldn't val be _equal_ to the value -
instead of or-ing the value in ?
I think it probably should and I also think if you are error checking
you should check your flagged bit actually appears in the read-back dword.
