Command Sequence
Operand Data:
The only operand is the longword address of the requested location.
Result Data:
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.

Write Memory Location (
WRITE
)
Write data to the memory location specified by the longword address. BAAR[TT,TM] defines address
space. Hardware forces low-order address bits to 0s for word and longword accesses to ensure that word
addresses are word-aligned and longword addresses are longword-aligned.
