CC1310: HW interrupt will result the whole task execution

dear champion,

my customer using TI Stack 15,4 and when they use the HW interrupt KEY_TIMER_EVT, it will result the whole task execution from the beginning.

where is the wrong could happen?

SDK version:1.60.0.21

example project: sensor

CCS version:8.0.0

compiler version: TI v16.9.6.TLS

if(Sensor_events & SENSOR_KEY_TIMER_EVT)
    {
        NV_userFlage_t  userFlage;
        uint8_t appKeyState=0;
        appKeyState=UserKeyStateCheck(PIN_getInputValue(PIN_KEY));
        switch(appKeyState)
        {
                case KEY_STATE_LONG://the key is holding low for 3s
                #if(ALLOW_DEBUG_FLAG)
                DevUartWrite("Key Long\r\n", 10);
                #endif
                Ssf_clearNetworkInfo();      //clear the network information
                userAtteSuccessFlag=false;   //re-certification
                userSendRSuccessFlag=false;
                userFlage.AtteSuccessFlag=false;
                DevDataUpdate_FLAGE(&userFlage);
                Jdllc_init(&Sensor_macCallbacks, &jdllcCallbacks);  //add by the customer and the initial function
                Ssf_setPollClock(devInfoBlock.pollInterval);//polling
                Util_setEvent(&Sensor_events, SENSOR_START_EVT); //begin beacon request
                Semaphore_post(sensorSem);    // wake the application
                break;
        }
        Util_clearEvent(&Sensor_events, SENSOR_KEY_TIMER_EVT);  

Best Regards,

Emma
