dsp28335 + w5500网络模块通过spi通信配置不同求大神帮忙有代码

Spi配置：
        SpiaRegs.SPICCR.bit.SPISWRESET = 0;//软件复位SPI
        SpiaRegs.SPICCR.all = 0x07;//数据长度为8bit、0x0007禁止内部回路模式模式0x0017开启
       
        SpiaRegs.SPICTL.all = 0x06;/使能Master/Slave XMIT
        SpiaRegs.SPISTS.all = 0x0000;//状态寄存器
        SpiaRegs.SPIBRR = 0x05;//设置波特率

        InitSpiGpio();//从初始化功能引脚
        SpiaRegs.SPICCR.bit.SPISWRESET = 1;//重新使能SPI



InitSpiGpio();//从初始化功能引脚
EALLOW;


    GpioCtrlRegs.GPAPUD.bit.GPIO16 = 0;   // Enable pull-up on GPIO16 (SPISIMOA)
    GpioCtrlRegs.GPAPUD.bit.GPIO17 = 0;   // Enable pull-up on GPIO17 (SPISOMIA)
    GpioCtrlRegs.GPAPUD.bit.GPIO18 = 0;   // Enable pull-up on GPIO18 (SPICLKA)
    GpioCtrlRegs.GPAPUD.bit.GPIO19 = 0;   // Enable pull-up on GPIO19 (SPISTEA)


    GpioCtrlRegs.GPAQSEL2.bit.GPIO16 = 3; // Asynch input GPIO16 (SPISIMOA)
    GpioCtrlRegs.GPAQSEL2.bit.GPIO17 = 3; // Asynch input GPIO17 (SPISOMIA)
    GpioCtrlRegs.GPAQSEL2.bit.GPIO18 = 3; // Asynch input GPIO18 (SPICLKA)
    GpioCtrlRegs.GPAQSEL2.bit.GPIO19 = 3; // Asynch input GPIO19 (SPISTEA)

    GpioCtrlRegs.GPAMUX2.bit.GPIO16 = 1; // Configure GPIO16 as SPISIMOA
    GpioCtrlRegs.GPAMUX2.bit.GPIO17 = 1; // Configure GPIO17 as SPISOMIA
    GpioCtrlRegs.GPAMUX2.bit.GPIO18 = 1; // Configure GPIO18 as SPICLKA
    GpioCtrlRegs.GPAMUX2.bit.GPIO19 = 0; // Configure GPIO19 as SPISTEA

    EDIS;

通过spi发送接收数据

       while(SpiaRegs.SPISTS.bit.BUFFULL_FLAG!=0);
        SpiaRegs.SPITXBUF = (byte<<8);//发送信息
        while(SpiaRegs.SPISTS.bit.BUFFULL_FLAG!=0);
        while(SpiaRegs.SPISTS.bit.INT_FLAG!=0)
                recvData = SpiaRegs.SPIRXBUF&0x00FF;
