address decoding for each peripheral. All peripheral register addresses are word aligned
(to 32-bit boundaries) regardless of their size. This eliminates the need for byte lane
mapping hardware that would be required to allow byte (8-bit) or half-word (16-bit)
accesses to occur at smaller boundaries. An implication of this is that word and half-word
registers must be accessed all at once. For example, it is not possible to read or write the
upper byte of a word register separately.
