napoleon leoni / InterruptMask

InterruptMask library allows masking/unmasking GPIO interrupts (attached to either the rise or falling edges). It also allows clearing pending interrupts which may come handy before unmasking them.

+// Note to get the actual pin number in the LPC of an mbed pin in P0
+// simply do pN-P0_0, for example p12-P0_0=17, that is pin 12 in the mbed
