I don't have a ready-made solution for you, but note that GDB
is scriptable.  If you look at Emacs's src/.gdbinit file
(http://git.savannah.gnu.org/cgit/emacs.git/tree/src/.gdbinit)
you can see what we do to help ourselves debug Emacs's C code.

Note how you can use C-like operations in it, so you could code up some
.gdbinit file for yourself where you write some handy commands that
print the state of your devices's registers in a meaningful manner.

Note that this is a "GDB-only" solution (the only Emacs part of it is
that you got the info in an Emacs discussion group, and that the sample
file provided came from Emacs's source code).
