interrupt pins on msp430F5529

Hello,

Which pins can be used for attachInterrupt on a msp430f5529?

All my attempt to attach interrupt failed on the 5529. The code was running on 2553, but now I wanted to try it with the 5529 i could not make it work.

<code>

attachInterrupt(P4_0, isr_left, FALLING);

</code>

Is the notation for attachInterrupt any different for 5529 or do we have to do something different.

Best,
