See: http://mbed.org/handbook/InterruptIn

Only pins on PortA and PortD can be used.

Accepted Answer

When I put the statement InterruptIn event(PTA2);

the printf (using USB serial) quits working on a Freescale KL25Z card. Comment it out and program works normally.

They decided to make the board as much equal as possible to the original Arduino board, so PTA1 and PTA2 are also the pins used for serial communication over USB.
