Description: Moves data between a data register and alt-
ernate bytes within the address space starting at the
location specified and incrementing by two. The high-
order byte of the data register is transferred first and
the low-order byte is transferred last. The memory
address is specified in the address register indirect plus
16-bit displacement addressing mode. This instruction
was originally designed for interfacing 8-bit peripherals
on a 16-bit data bus, such as the MC68000 bus.
