Pushbutton interrupt code MSP430FR4133

  Hi. I am trying tot write a simple code that will turn on an LED when I push a button but something is wrong with my code and I can't figure it out.

I am using the msp430fr4133 LaunchPad.

Can you tell me where I did wrong?

Thank you.

Here is the code:

//interrupt with push button


#include <msp430.h> 





int main(void)
{
WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer
P1DIR |= BIT0; // Set P1.0 to output direction

P1OUT &= ~BIT0; // set P1.0 to 0 (LED OFF)

P1IES = 0x00;  //low to high transition

P1IE |= BIT2; // P1.2 interrupt enabled

P1IFG &= ~BIT2; // P1.2 IFG cleared

PM5CTL0 &= ~LOCKLPM5;

__bis_SR_register(LPM0_bits | GIE);          // Enter LPM0 w/ interrupt
       __no_operation();


}


// Port 1 interrupt service routine

#pragma vector = PORT1_VECTOR
__interrupt void PORT1_ISR(void)
{
P1OUT |= BIT0; // led on

}
