Fixed.

Yeah, and as you can see the two are overlapping. I'd like to keep it
like this as a memory aid.

Yes; do you prefer adding that to the comment, or dropping the register
altogether?

Yes. I dropped the XXX comment. Another spec names the reg as
DBI_FIFO_THROTTLE, which I'm inclided to trust as it matches the
contents.
