100 200 300 400 . In little endian, this would be
stored as: ix: 0 1 2 3
val: 400 300 200 100
[400]. It's easier to directly
acess in little endian as just data[0], instead of in big endian where
it would be data[3]. So, storing stuff backwards makes it easier to chop off
the LSBs data, since that's the suffix .
