AM3352: AM3352 的串口配置

请问如果不适用FIFO DMA模式，串口能正常收发数据么？

可以正常接收单个字节的数据，但连续接收多个字节的话，发送的第 1~9个字节会放在缓存的2~10，发送的第10个字节会放在第一个缓存里。

单个字节接收的配置为：   
        UART0_Module_ClkConfig();           //使用UART0自己的时钟
        UART_PinMux_Setup(0);               /* Performing the Pin Multiplexing for UART0 instance. */
        UARTModuleReset(UART0_BASE_ADD); /* Performing a module reset. */
        UartFIFOConfigure(UART0_BASE_ADD);             /* Performing FIFO configurations. */
        UartConfigure(UART0_BASE_ADD,BAUD_RATE_9600, (UART_FRAME_WORD_LENGTH_8 | UART_FRAME_NUM_STB_1 | UART_PARITY_NONE));

void UartFIFOConfigure(unsigned int baseAdd)
{
    unsigned int fifoConfig = 0;

    /*
    ** - Transmit Trigger Level Granularity is 4
    ** - Receiver Trigger Level Granularity is 1
    ** - Transmit FIFO Space Setting is 56. Hence TX Trigger level
    **   is 8 (64 - 56). The TX FIFO size is 64 bytes.
    ** - The Receiver Trigger Level is 1.
    ** - Clear the Transmit FIFO.
    ** - Clear the Receiver FIFO.
    ** - DMA Mode enabling shall happen through SCR register.
    ** - DMA Mode 0 is enabled. DMA Mode 0 corresponds to No
    **   DMA Mode. Effectively DMA Mode is disabled.
    */
    fifoConfig = UART_FIFO_CONFIG(UART_TRIG_LVL_GRANULARITY_4,
                                  UART_TRIG_LVL_GRANULARITY_1,
                                  UART_FCR_TX_TRIG_LVL_56,
                                  1,
                                  1,
                                  1,
                                  UART_DMA_EN_PATH_SCR,
                                  UART_DMA_MODE_0_ENABLE);

    /* Configuring the FIFO settings. */
    UARTFIFOConfig(baseAdd, fifoConfig);
}

接收函数的判断标志为：

 while((HWREG(reg + UART_LSR)&0x01) == 1)
    {
         paramType->RxFlag = 1;
         paramType->Root.Buffer[num][len++] = UARTCharGetNonBlocking(reg);
         paramType->Root.Clen[num]++;
    }
