4.2.1 DATA SPACE WIDTH
The data memory space is organized in
byte-addressable, 16-bit wide blocks. Data is aligned
in data memory and registers as 16-bit words, but all
data space EAs resolve to bytes. The Least Significant
Bytes (LSBs) of each word have even addresses, while
the Most Significant Bytes (MSBs) have odd
addresses.
