...much of which resolves into a single hardware register read/write!
A lot of the driver library 'magic' is in the symbolic constants in
the header files.

The library is great for getting things going - use the debug version
and it validates the 'constants' you pass in.

Exact IO timing on the output pins is difficult to say the least.
It's not specified and I went through an interesting exchange on the
question of how long it takes between a write to a port and a read
from the same port... it's on one of the Luminary forums.
