2.3.1. Little-endian format

In little-endian format, the lowest addressed byte in a word is considered the least-significant byte of the word and the highest addressed byte is the most significant. So the byte at address 0 of the memory system connects to data lines 7 through 0.

For a word-aligned address A, Figure 2.1 shows how the word at address A, the halfword at addresses A and A+2, and the bytes at addresses A, A+1, A+2, and A+3 map on to each other when the core is configured as little-endian.
