Ok, fair enough. I had missed 2) and 3) here. It could still be done
as a structure (rather than function pointers) with individual named
members for each register offset along with bool flags for 2) and
integers to describe 3).

Please that suggestion some thought, and then decide for yourself,
I won't complain if you keep the current version.
