3.2. Memory Formats

The bigend bit in the Control Register selects whether the ARM720T treats words in memory as being stored in big-endian or little-endian format. See Chapter 4 Configuration for more information on the Control Register.

ARM720T views memory as a linear collection of bytes numbered upwards from zero. Bytes 0 to 3 hold the first stored word, bytes 4 to 7 the second and so on. ARM720T can treat words in memory as being stored either in big-endian or little-endian format.
