No this is not possible, and I'm sorry for not explaining it better. The pin is not controlled by me. It is implicitly set/cleared via the memory controller, but it doesn't matter because we have external logic forcing it high. Having the possibility to control this pin in software wouldn't make it "hardware write protection" would it? The protection state is kept by an external AVR and in order to enable write access both a jumper and a write protection flag must be set.
