B.5 Storage Reference Instructions
The PPC405 uses load and store instructions to transfer data between memory and the general purpose registers.
Load and store instructions operate on byte, halfword and word data. The storage reference instructions also
support loading or storing multiple registers, character strings, and byte-reversed data. Table B-6 shows the
storage reference instructions available for use in the PPC405.
