CAN, TE, Filter, LTE, ni

如下是配置为只接收扩展帧0x1314的筛选器配置，请问我想配置为只接收标准帧某个ID的话，应该怎么修改呢？？？
static void CAN_Filter_Config(void)
{
      CAN_FilterInitTypeDef  CAN_FilterInitStructure;


      CAN_FilterInitStructure.CAN_FilterNumber=0;
      CAN_FilterInitStructure.CAN_FilterMode=CAN_FilterMode_IdMask;
      CAN_FilterInitStructure.CAN_FilterScale=CAN_FilterScale_32bit;


      CAN_FilterInitStructure.CAN_FilterIdHigh= ((((u32)0x1314<<3)|CAN_ID_EXT|CAN_RTR_DATA)&0xFFFF0000)>>16;
      CAN_FilterInitStructure.CAN_FilterIdLow= (((u32)0x1314<<3)|CAN_ID_EXT|CAN_RTR_DATA)&0xFFFF;
      CAN_FilterInitStructure.CAN_FilterMaskIdHigh= 0xFFFF;
      CAN_FilterInitStructure.CAN_FilterMaskIdLow= 0xFFFF;
      CAN_FilterInitStructure.CAN_FilterFIFOAssignment=CAN_Filter_FIFO0 ;
      CAN_FilterInitStructure.CAN_FilterActivation=ENABLE;
      CAN_FilterInit(&CAN_FilterInitStructure);

      CAN_ITConfig(CANx, CAN_IT_FMP0, ENABLE);
}
