From looking at your changes I see a lot of similarities in our code with the exception being the mechanism for banked register support. The difference being that your approach is a bit more explicit in the declaration of the banked registers. Whereas my approach was to update the banked registers once all the other registers were registered. Both approaches I believe work. > > I spoke with Peter M. and he and I are okay with your approach.
