xx...xx00 is in the least-significant byte position (little end).
In byte diagrams, bit positions are numbered from right to
left —the little end is on the right and the big end is on the
left. Data structure diagrams in memory show low addresses
at the bottom and high addresses at the top. When data
items are aligned, bit notation on a 64-bit data bus maps
directly to bit notation in 64-bit-wide memory. Because byte
addresses increase from right to left, strings appear in
reverse order when illustrated.
example, bits 9–1). When accompanied by a signal or bus
name, the highest and lowest bit numbers are contained in
brackets and separated by a colon (for example, AD[31:0]).
