Could I use any GPIO pin as interrupt input signal which worked at edge detection mode?

Hi，

Because 6 dedicated IRQ(0~5) pins are not enough for me, I need other GPIO pin work as interrupt input signal. So, I have below two questions:

1. Could any GPIO be used as interrupt signal input, which worked at edge detection mode? 

2. If above 1 is yes, what difference between dedicated IRQ and GPIO?  Maybe is response priority?

Thanks in advance!

Best regards!
