S9KEAZ128AMLK型号MCU KBI中断

请教各位大神；KBI中断设置为高电平触发，进入中断程序后，如果加上判断中断源引脚的程序，则读KBI1_SP寄存器的值为0x000000，如果不加上判断语句，则第一次读的值为0x000000，以后近中断读的值为0x00002000，与预期相符；中断引脚使能寄存器配置为0x000000；改引脚进入中断后使能为GPIO输入输出，做OWI通讯；
以下为我的中断初始化及服务程序：void KBI_PIR_Init_app(void)
{
      uint32_t       i;
      KBI_ConfigType  sKBIConfig;
      MCU_drive_dis;
      DOCI_R;

      /* Disable all the KBI pins */
      for (i = 0; i < KBI_MAX_PINS_PER_PORT; i++)
      {
            sKBIConfig.sPin[ i].bEn       = 0;
      }

      sKBIConfig.sBits.bRstKbsp = 1;/*Writing a 1 to RSTKBSP is to clear the KBIxSP Register*/
      sKBIConfig.sBits.bKbspEn = 1;/*The latched value in KBxSP register while interrupt flag occur to be read.*/
      sKBIConfig.sBits.bMode = KBI_MODE_EDGE_LEVEL;
      sKBIConfig.sBits.bIntEn  = 1;

      sKBIConfig.sPin[KBI1_PTF5_SHIFT].bEdge = KBI_RISING_EDGE_HIGH_LEVEL;
      sKBIConfig.sPin[KBI1_PTF5_SHIFT].bEn = 1;

      KBI_SetCallback(KBI1, &KBI1_PIR_Task);
      KBI_Init(KBI1, &sKBIConfig);
}

void KBI1_PIR_Task(void)
{
      KBI_mark=KBI_GetSP(KBI1);
      //if(KBI_mark == KBI1_PTF5_MASK)  加上此判断，每次读取值为0x000000；
      {
            KBI_DisableInt(KBI1);
            KBI_RstSP(KBI1);
            MCU_drive_dis;
            delay10us_PC(8);
            GPIO_read=FGPIO_Read(FGPIOB);
            if(GPIO_read&0x2000) //delete glitch
            {

                     DOCI_read_data=DOCI_read();
                     global_uart_send[4]=DOCI_read_data>>8;
                     global_uart_send[5]=DOCI_read_data;
                     global_uart_send[0]=MCU_ADDR;
                     global_uart_send[1]=0x07;
                     global_uart_send[2]=0x06;
                     global_uart_send[3]=0x00;
                     global_uart_send[6]=Cal_CRC(global_uart_send,global_uart_send[1]-1);
                     UART_SendWait_app(UART1);
                     UART_clear();
                     UART_send_num++;
            }
      }
      KBI1->PE |= 0x2000;
      KBI_EnableInt(KBI1);
}
