The DES IV is loaded into a DES algorithm which is (hopefully!) highly
positionally dependent.

Since the SPI is arbitrary, it doesn't really make any difference what
order you interpret it in. You can interpret it in either little or
big endian order and it won't alter your operation (so long as you are
consistant, of course!)
