What's really good about it is that this is a straight design now,
from the IC designers to the compiler/library.  This would not have
been possible (at least not that way) with the previous AVR designs.
Part of the picture is that each peripheral now consists of a
well-defined set of registers starting at a particular base address,
so combining them into a single struct is just a logical consequence.

(Recent ATmegas are much closer to this than early AT90s but still
quite a mile away from the ATmega design.)
