Big-Endian Mode
The following example demonstrates the operation of a system in big-endian mode starting
with a program that does the following:
store string ("hello, world") at 0x000
store pointer (0xFEDCBA98) at 0x010
store half word (0d1234) at 0x00E
store byte (0x55) at 0x00D
If the data is stored into local memory, it appears as shown in Figure B-2.
