5.5.3.3.3
Read data at the longword address. Address space is defined by BAAR[TT,TM]. Hardware forces
low-order address bits to zeros for word and longword accesses to ensure that word addresses are
word-aligned and longword addresses are longword-aligned.

The only operand is the longword address of the requested location.
Word results return 16 bits of data; longword results return 32. Bytes are returned
in the LSB of a word result, the upper byte is undefined. 0x0001 (S = 1) is returned
if a bus error occurs.
