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,
