Extern irq on TWRMCF52259

In the reference manual, in the eport chapter, I have ridden there are up to eight interrupt pins. There are only four extern IRQ (IRQ7,IRQ5,IRQ3,IRQ1), so which are the other four?

 

And in the TWRMCF52259, what pin can I use for an extern interrupt? The switches aren't connected to this pins.

 

Thanks
