A simple example that uses the GPIO group and pin interrupts. LED1 turns on when P21 and P22 are grounded (using group 0 interrupt) LED1 turns of when P23 or P24 are grounded (using group 1 interrupt) LED2 turns on when P19 is grounded (using GPIO interrupt 0) LED2 turns off when P18 is grounded (using GPIO interrupt 1)
History

Changed interrupt priority comment, the CortexM0 has four levels 0-3.
Moved the SetPriority function before the interrupt enable. In CortexM0 the priority shouldnt be changed while the interrupt is enabled
