Using VEX range finder on the full-size FRC

[CronosPrime1]

I was trying to hook up a VEX infrared range finder to the full-sized robot. On the VEX robot, the sensor is supposed to be hooked up to two interrupt ports. I need to hook up my sensor to the full-sized FRC. What do the interrupt ports on the VEX robot do, and is there an equivalent on the full-sized FRC? Can I just hook up the connectors that are supposed to go into the VEX interrupt ports to any digitial I/O port?
