Initial Read or Write Port?

If you are wanting to use the ports in anything other than their default configuration you need to initialise the relevant port registers (direction, function etc). Note that the sample programs usually have calls to brdInit() which setup the port registers for the core modules corresponding prototype boards. If using your own hardware you may need to make your own "brdInit" function.
