Please explain what configuration of a board would cause these to be swapped, rather than why someone might want to configure the board this way. I've got no idea what this hardware is actually doing, so this is being pulled out of a hat, but I'd expect something like "Some boards swap the polarity of the P/N pins, use this property to indicate this to software". > + type: boolean The type here should be flag.
