str731 的can 接受进不了中断为什么

下面是初始化程序
      CAN_InitTypeDef CAN0Init;
      CAN0Init.CAN_Mask = CAN_CR_IE| CAN_CR_CCE | CAN_CR_DAR;
      CAN0Init.CAN_Bitrate = CAN_BITRATE_100K;

    // initialize the interrupt controller
    EIC_IRQChannelConfig(CAN0_IRQChannel, ENABLE);
    EIC_IRQChannelPriorityConfig(CAN0_IRQChannel, 1);
    EIC_IRQCmd(ENABLE);

    // initialize the CAN at a standard bitrate,
           interruptsenabled
    CAN_Init(CAN0, &CAN0Init);

    // switch into Loopback+Silent mode (self-test)
    //CAN_EnterTestMode(CAN0,
               CAN_TESTR_SILENT);//CAN_TESTR_LBACK );//|
              把上面注销了因为之前是测试模式
    // configure the message objects
    CAN_InvalidateAllMsgObj(CAN0);


    CAN_SetTxMsgObj(CAN0, CAN0_TX_MSGOBJ, CAN_EXT_ID);
    CAN_SetRxMsgObj(CAN0, CAN0_RX_MSGOBJ, CAN_EXT_ID, 0,
                         CAN_LAST_EXT_ID, TRUE);


    // reception and release are done in the interrupt handler

    wait();

    GPIO_BitWrite(GPIO4,LD10,Bit_SET);//LED10

    // switch back into Normal mode
    //CAN_LeaveTestMode(CAN0);

    // disable interrupts globally
    //EIC_IRQCmd(DISABLE);
}

只是把进入测试模式的语句注销   可是为什么进不了中断
  那里还要配置呢  str731  求救
