CCS/MSP432P401R: Verify toggle on P2.3 with interruption

Part Number: MSP432P401R

Tool/software: Code Composer Studio

Hello fellows,

I am trying to verify when the pin P2->IN change is state, but I have try everything and I don't get anything with success. So my intention is each time the P2.3 goes from low to High and High to low an interrupt occurs, and the blue led blink, anyone can help me?
