MSP432P401R: Digital input pin does not trigger interrupt for PM0

Hi,

I have a motion sensor attached with Digital Output of the sensor is connected to PM0 of controller.

I have configured the PM0 pin for edge triggered but my ISR is not being invoked.

Is it allowed to raise interrupt for PM0? (If I scan the input pin PM0, I see that level changes as expected but does not trigger interrupt)

My code snippet :

int myVar;


int main(void)
{
    /* Call driver init functions */
    Board_init();

    motionSensorInit();

    /* Initialize the GPIO since multiple threads are using it */
    GPIO_init();

    setupOneSecTimer();

    /* Start the TI-RTOS scheduler */
    BIOS_start();

    return (0);
}


void gpioMotionSensorInt(uint_least8_t index)
{
    myVar++;
}
void motionSensorInit()
{
    myVar = 0;

    GPIO_setConfig(GPIO_MOTION_SENSOR, GPIO_CFG_IN_PU | /*GPIO_CFG_IN_INT_RISING*/ GPIO_CFG_IN_INT_BOTH_EDGES);

    GPIO_setCallback(GPIO_MOTION_SENSOR, gpioMotionSensorInt);
    GPIO_enableInt(GPIO_MOTION_SENSOR);
