And "stores integers in big-endian form" is not unconditionally true. There are the LOAD REVERSED and STORE REVERSED instructions which load and store, respectively, the bytes in the register specified into the memory location specified in reverse sequence. I.e. bytes 0..3 or 0..7 load or store into bytes 3..0 or 7..0 of the specified memory location. Of course, integers in registers do need to be in big-endian format in order to be used for arithmetic operations (at least if you want the correct result).
