CC1310: pin_shutdown and I/O interrupt

Part Number: CC1310

I implemented a code to exchange interrupts between two devices like this:

DEVICE 1 I press the button0 and the DEVICE 2 answers me with LED0 on.

Now to this code, I am implementing pin_Shutdown to have a very low consumption after I send it to the command. For the moment I have declared a button that I don't use and the shutdown works.

Can I use the buttons I use to send the command and then send it to shutdown?

I implemented this, but I have problems:

The device sends the command but does not go into shutdown.

PIN_Config ledPinTable[] =
{
	LED_1   | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX,
        LED_2   | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX,
        BUTTON_0 | PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_NEGEDGE,	
	PIN_TERMINATE
};

PIN_Config ButtonTableWakeUp[] = {
        BUTTON_0 | PIN_INPUT_EN | PIN_PULLUP | PINCC26XX_WAKEUP_NEGEDGE,
                        
    PIN_TERMINATE                                 /* Terminate list */
};

/* Shutdown Button pin table */
PIN_Config ButtonTableShutdown[] = {
       BUTTON_0| PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_NEGEDGE,
                          
    PIN_TERMINATE                                 /* Terminate list */
};

static void buttonClockCb(UArg arg) {
    PIN_Handle buttonHandle = (PIN_State *) arg;


    Clock_stop(hButtonClock);


    if (activeButtonPinId != PIN_TERMINATE) {

        if (!PIN_getInputValue(activeButtonPinId)) {

            switch (activeButtonPinId) {
            case BUTTON_0:
                Semaphore_post(Semaphore_handle(&shutdownSem));
                break;
            default:

                break;
            }
        }
    }


    PIN_setConfig(buttonHandle, PIN_BM_IRQ, activeButtonPinId | PIN_IRQ_NEGEDGE);


    activeButtonPinId = PIN_TERMINATE;
}

static void buttonCb(PIN_Handle handle, PIN_Id pinId) {

    activeButtonPinId = pinId;


    PIN_setConfig(handle, PIN_BM_IRQ, activeButtonPinId | PIN_IRQ_DIS);


    Clock_setTimeout(hButtonClock, (50 * (1000 / Clock_tickPeriod)));
    Clock_start(hButtonClock);
}

static void taskFxn(UArg a0, UArg a1)
{

    Semaphore_pend(Semaphore_handle(&shutdownSem), BIOS_WAIT_FOREVER);

    PINCC26XX_setWakeup(ButtonTableWakeUp);

    Semaphore_pend(semHandle, BIOS_WAIT_FOREVER);

    Power_shutdown(0, 0);

    while (1);
}

void Send_Button_Command(PIN_Handle handle, PIN_Id pinId)
{
    CPUdelay(8000*50);
	if (!PIN_getInputValue(pinId))
	{
	  switch(pinId){

	  case BUTTON_0:
	        //SEND COMMAND TO TURN ON LED 1 ON SECOND DEVICE
                Semaphore_post(semHandle);
	        break;
               
	  }
	}
}

Thanks
