Where are the interrupt pins on NUCLEO-F411RE?

I just got the board yesterday and I cannot find the locations of interrupt pins. Can someone help me out?

Thanks

If you use a recent version of the mbed lib (right mouse button, update in the online compiler): Every unique numbered pin. That means you can use any pin as InterruptIn, but you cannot use multiple pins with the same number on a different port as InterruptIn. So you can use PA_1, PB_2, PA_3, PC_4, etc. But in this example you could not use also PE_1.

if i use PA_1 as InterruptIn, Can i use PH_1 as DigitalIn or DigitalOut ?

Yes, just not as InterruptIn.
