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.
