2.10.1. Byte-invariant big-endian format

In byte-invariant big-endian format, the processor stores the most significant byte of a word at the lowest-numbered byte, and the least significant byte at the highest-numbered byte. Therefore, byte 0 of the memory system connects to data lines 31-24 as Figure 2.8 shows.
