cc2630 sensor controller

hi all,

we need optimal the power comsumption with the pheripheral .

(ie . use button to trigger led or buzzer in no RF work)

i think that Sensor Controller module should be do it . 

so ,about the  Sensor Controller which have some question need clear.

1.  Sensor Controller

    ref,CC13xx, CC26xx SimpleLink Wireless MCU Technical Reference Manual) 1.3.10 Sensor Controller

     Sensor Controller that is work in the power down mode . 

     how to vertifcation the action and let system in to power down mode ?

2.integrating  "LED Blinker" project into SampleSwitch project, 

  in my platform ,it show a warning about the linker : how to solve it ? it information overlap in the vector .

"Warning[Lp023]: absolute placement (in [0x20000000-0x200000c7]) overlaps with reserved areas: C:\ti\simplelink\zstack_home_1_02_02a_44539\Projects\zstack\HomeAutomation\SampleSwitch\CC26xx\cc26xx_app.icf 178"

void ctrlReadyCallback(void) {

} // ctrlReadyCallback




void taskAlertCallback(void) {

    // Clear the ALERT interrupt source
    scifClearAlertIntSource();

    if (scifGetTaskIoStructAvailCount(SCIF_LED_BLINKER_TASK_ID, SCIF_STRUCT_OUTPUT) == 1) {
        SCIF_LED_BLINKER_OUTPUT_T* pOutput = scifGetTaskStruct(SCIF_LED_BLINKER_TASK_ID, SCIF_STRUCT_OUTPUT);
        if (pOutput->counter & 0x0001) {
            HWREG(GPIO_BASE + GPIO_O_DOUTSET31_0) = BV(Board_LED1);
