目前正在调试SRIO doorbell中断程序，slave断已经能够正常接收到doorbell信息，并且相应的标志位也已经有了响应。但是slave端就是不进中断程序，接下来也不知道怎么去调试。
程序是触发INTDST0中断。接收到信号之后INTDST0_DECODE中的最后一位也被置为了1。大神指点一下该怎么去调试吧。不知道接下去怎么去做了。还有就是INTDST0_RATE_CNTL这个寄存器到底是什么意思啊。看半天文档都看不明白。
中断设置程序如下：
void initInt()
{

      CSL_IntcContext          intcContext;
      CSL_IntcGlobalEnableState state;
      CSL_IntcEventHandlerRecord  EventRecord;
      CSL_IntcParam             vectId;
      CSL_Status                                     status;
      CSL_IntcObj                SrioIntcObj;
      CSL_IntcHandle             SrioIntcHandle;
      CSL_IntcEventHandlerRecord  record[11];

      RIO_DOORBELL0_ICCR = 0xffffffff;
      RIO_DOORBELL1_ICCR = 0xffffffff;
      RIO_DOORBELL2_ICCR = 0xffffffff;
      RIO_DOORBELL3_ICCR = 0xffffffff;
      DSP_EVTCLR0 = 0xffffffff;
      DSP_EVTCLR1 = 0xffffffff;
      DSP_EVTCLR2 = 0xffffffff;
      DSP_EVTCLR3 = 0xffffffff;

      intcContext.eventhandlerRecord = record;
intcContext.numEvtEntries    = 11;
         status = CSL_intcInit(&intcContext);
      if (status != CSL_SOK) {
      printf("Intc initialization failed\n");
      return;
         }

      /* Enable NMIs */
      status = CSL_intcGlobalNmiEnable();
      if (status != CSL_SOK) {
            printf("Intc global NMI enable failed\n");
                     return;
      }

      /* Enable global interrupts */
      status = CSL_intcGlobalEnable(&state);
      if (status != CSL_SOK) {
               printf ("Intc global enable failed\n");
                     return;
      }

      /* Opening intc module */
      vectId = CSL_INTC_VECTID_8;
      SrioIntcHandle = CSL_intcOpen (&SrioIntcObj, CSL_INTC_EVENTID_RIOINT0, \
                                    &vectId , NULL);

      if (SrioIntcHandle == NULL) {
               printf("Intc open failed\n");
                     return;
      }

      EventRecord.handler = (CSL_IntcEventHandler)&eventSrioHandler;
         EventRecord.arg = (void*)(SrioIntcHandle);
status = CSL_intcPlugEventHandler(SrioIntcHandle,&EventRecord);

if (status != CSL_SOK) {
      printf("Intc plug event handler failed\n");
      return;
}

      CSL_intcHwControl(SrioIntcHandle, CSL_INTC_CMD_EVTCLEAR, NULL);
      CSL_intcHwControl(SrioIntcHandle, CSL_INTC_CMD_EVTENABLE, NULL);

}
