Do you know of any Motorola documentation that addresses this issue
specifically?
Thanks.
All the motorola documentation states that byte accesses are not
permitted, as does the TPU microcoding guide.
I've just tried it out and byte reads work correctly, for both odd and
even addresses.
A byte write erases the other part of the halfword.
E.g. writing 0x42 to an even byte address will result in 0x4200 being
written to the halfword.
