STM8S105K4串口2无奇偶校验，也能接收偶校验的数据为什么？

MCU STM8S105K4    设置为一个起始为，8个数据位，无校验，一个停止位，用串口助手 发送能够 接收的数据，还是正确的，
static void UART_Config(void)
UART2_DeInit();
       UART2_Init((uint32_t)9600, UART2_WORDLENGTH_8D, UART2_STOPBITS_1, UART2_PARITY_NO,
        UART2_SYNCMODE_CLOCK_DISABLE, UART2_MODE_TXRX_ENABLE);
     }

      /* Enable the UART Receive interrupt: this interrupt is generated when the UART
    receive data register is not empty */
     UART2_ITConfig(UART2_IT_RXNE_OR, ENABLE);

     /* Enable UART */
     UART2_Cmd(ENABLE);
     /* Enable general interrupts */
     enableInterrupts();

中断接收
INTERRUPT_HANDLER(UART2_RX_IRQHandler, 21)
{
    /* In order to detect unexpected events during development,
       it is recommended to set a breakpoint on the following instruction.
    */
     unsigned char temp=0;
    unsigned char temp_state=0;
    /* Read one byte from the receive data register */
  
/*   temp_state=UART2->SR;
       if(temp_state 0x01)                         // 奇偶 ERROR
     {
       temp=8;
      UART2_ReceiveData8();
      //return;
    }
    else*/
   
    temp_state=UART2->SR;
       if((temp_state 0x01)!=1)
     //if(UART2_GetITStatus(UART2_IT_PE) == RESET)
     {
        temp=UART2_ReceiveData8();
   }

}
不知道是不是 哪里设置错了
