2.4.2
All ColdFire processors use a big-endian addressing scheme. The byte-addressable organization of
memory allows lower addresses to correspond to higher order bytes. The address N of a longword data
item corresponds to the address of the high-order word. The lower order word is located at address N + 2.
The address N of a word data item corresponds to the address of the high-order byte. The lower order byte
is located at address N + 1. This organization is shown in
