I have tested this fault scenario with a transfer beginning
at a single byte at the end of a mapped page only, which IMO
does violate m68k alignment rules. I cannot remember ever
seeing such faults reported from conforming software before.
68020+ does support unaligned data accesses, so IMHO such transfers
are valid. For compatibility with 68000/68008/68010/68012, data is
recommended to be 2-byte aligned.
Instructions must always be aligned to 2 bytes, though.
