MOVE.BP
MOVEU.B
MOVE.B
MOVE.W
MOVE.L
Operation
1.The destination operand X:xxxx is always specified as a byte address for the MOVE.BP, MOVEU.B, and
MOVE.B instructions. The upper 15 bits of the address select the appropriate word location in memory, and
the LSB selects the upper or lower byte of that word.
