User manual
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.
