I remember well one time long ago when I did that. I had done the firmware for a piece of hardware that had some DIP switches to configure. I was having trouble doing the documentation for what each switch did and when you would want to configure it a particular way. Finally I realized it was because the switches weren't laid out logically, so I wrote the documentation the way I thought it should work then changed the code to match the documentation. Win-win, easier documentation and easier to use hardware.
