Sorry, I was wrong about this... the manual does not say 1 or 32. It says: "Port A can be configured to generate multiple interrupt signals or a single combined interrupt flag. When set to 1, the component generates a single combined interrupt flag."
There is no other text describing this option, but I believe all GPIOs on port A will have an interrupt. In our case we have 32 GPIOs on port A and 32 interrupts connected to them.
Thanks Phil
