One thing to watch out for here is that when you write something like:
...
setPinHi();
test code ...
setPinLo();
...
you might not be timing all of the test code, or only the test code.
The compiler can often move the code around the "setPin" statements,
especially if they are macros or functions that the compiler can see
during the compilation.
