5.2.4.2.5 Integer Load and Store Multiple Instructions
The integer load/store multiple instructions move blocks of data to and from the GPRs. In some
implementations, these instructions are likely to have greater latency and take longer to execute, perhaps
much longer, than a sequence of individual load or store instructions that produce the same results.
When the MPC885 is operating with little-endian byte order, execution of a load or store multiple
instruction causes the system alignment error handler to be invoked; see "Byte Ordering" in Chapter 3,
"Operand Conventions," in the Programming Environments Manual for more information.

5.2.4.2.6 Integer Load and Store String Instructions
The integer load and store string instructions allow movement of data from memory to registers or from
registers to memory without concern for alignment. These instructions can be used for a short move
between arbitrary memory locations or to initiate a long move between misaligned memory fields.
When the MPC885 is operating with little-endian byte order, execution of a load or store string instruction
causes the system alignment error handler to be invoked; see "Byte Ordering" in Chapter 3, "Operand
Conventions," in the Programming Environments Manual for more information.
