c6657 set up an interrupt on a GPIO16 through CIC0

I set up an interrupt on GPIO16 through CIC0. The systhem interrupt(CIC0 input) number is 0 and the host interrupt(CIC0 output) number is 1. Event id=23. I use the INT4. GPIO16 is setted the input IO. However, it can't run into the interupt dealing fuction when the gpio16 is high.

My code use sysbios module. Can I use csl on this situation.

static void SetInterrupt()
{
    // CSL_GpioHandle hGpio;
    Error_Block eb;
    Hwi_Params hwiParams;
    Hwi_Handle hwi0;
    int sysInterrupt=0;
    System_printf("enter main()\n");
    System_flush();

    // Open the CSL GPIO Module 0
    hGpio = CSL_GPIO_open (0);
    KICK0 = 0x83e70b13;
    KICK1 = 0x95a4f1e0;
    PIN_CONTROL_0 = 0xFFFF0000;
    CSL_GPIO_setPinDirInput ( hGpio, 16) ; //set pin as input
    CSL_GPIO_setRisingEdgeDetect (hGpio, 16); // Set interrupt detection on GPIO pin 1 to rising edge
    CSL_GPIO_bankInterruptEnable (hGpio, 1);
    // Enable GPIO per bank interrupt for bank zero
    //chip-level INTC0 is for corepac0~1
    hnd = CSL_CPINTC_open(0);
    if (! hnd) {
        return;
     }
    //disable all host interrupt
    CSL_CPINTC_disableAllHostInterrupt(hnd);
    //configure no nesting support in the cpintc module
    CSL_CPINTC_setNestingMode (hnd, CPINTC_NO_NESTING);
    CSL_CPINTC_clearSysInterrupt (hnd, 0);
    //enable system interrupt 0
    CSL_CPINTC_enableSysInterrupt (hnd, 0);
    //map system interrupt 0(gpio16 gpint) to host interrupt 1
    CSL_CPINTC_mapSystemIntrToChannel (hnd, 0, 1);
    //enable host interrupt 1
    CSL_CPINTC_enableHostInterrupt (hnd, 1);
    //enable all host interrupts
    CSL_CPINTC_enableAllHostInterrupt(hnd);

    Error_init(&eb);
    Hwi_Params_init(&hwiParams);
    hwiParams.eventId = 23;
    // params.eventId = 86;
    // hwiParams.enableInt = 1;

    // params.arg = sysInterrupt;
    hwiParams.enableInt = 1;
    hwiParams.arg = 1;
    hwiParams.priority =1;
    hwi0=Hwi_create(4, (ti_sysbios_hal_Hwi_FuncPtr) &hwiFunc, &hwiParams, &eb);
    // hwiParams.enableInt = 1;
    if(hwi0==NULL)
    {
        System_abort("Hwi create failed");
    }
}

void hwiFunc(UArg sysInterrupt)
{

    // CSL_CPINTC_disableHostInterrupt(hnd, 1);
    // CSL_CPINTC_clearSysInterrupt(hnd, sysInterrupt);
    flag = 1;
    // CSL_CPINTC_enableHostInterrupt(hnd, 1);
