Basically, turn on the interrupt and register the handler with the VIC.
Then enable the pin interrupts using IO2IntEnR for rising edge or IO2IntEnF for falling.
In your interrupt handler you then check what pins have active interrupts with
IOxi20IntStatR or IO2IntStatF and then clear them once acted on using IO2IntClr

Hi

I am trying to using P2.27 and P2.26 as input interrupt pins.
I understand the these interrupts shares the EXINT3 interrupt vector

Has anyone have an example using this function
