Hardware interrupt not working

I'm running OpenMSP430 in Vivado. I am simply trying to implement a button.

P1DIR = 0x00;
P1IE = 0x01;
P1IES = 0x00;
P1IFG = 0x00;

interrupt(PORT1_VECTOR) port1_isr(void) {
P3OUT=40;
P1IFG &= ~0x01;
}

Setting a constant value on p1_din does not change the value of P3OUT though. What could be causing this. Maybe my PMEM and DMEM configurations?
