GPIO Interrupts on LPC546xx

Looking at the latest LPC546xx datasheet (2.6) it says in section 7.15.1 GPIO Features that:

 

* All GPIO pins can be selected to create an edge or level-sensitive GPIO interrupt request

 

I need to get an interrupt from pin P4.7 but I cannot see how to achieve this. Both the PINT and GINT blocks only appear to function on GPIO ports 0 or 1 and I can't see any interrupt function in the GPIO block.

 

I'm clearly missing something as the datasheet is quite clear that all GPIO pins can generate an interrupt.

 

Thanks for any help,

 

Andy
