Cyclone III On-Chip Termination

Hi, I was wondering if anyone had a tutorial or instructions on how to enable the on-chip termination for the Cyclone III? On the Altera website, they mention that it can be done via assignment...

I was talking about the RUP and RDN pins. I've tied resistors to these pins to either VCC or gnd (as specified in the datasheets) so that I can use them for OCT. They will be matched to 50 Ohm resistors. How do I make sure that the pin planner doesn't use the RUP and RDN pins for other I/Os?
