I don't think this pin is referenced in software, at least not in this register, AFAICS. The only reason why Kyungmin mentioned it and why it is mentioned in the datasheet in the description of this register, is that this pin defines the selection between NAND and OneNAND - along with some other pins (OM[4:1] or some such). So, you cannot set this pin in software, you cannot read this pin in software (I think), maybe you have to switch a jumper when selecting another configuration, but that again has little to do with software, IMHO.
