请帮我写一下dsp28335使用xintf进行通信的C语言代码

好的，下面是使用dsp28335的xintf进行通信的C语言代码示例：

// XINTF配置
void InitXintf(void)
{ 
    // 选择XINTF的GPIO引脚
    EALLOW;
    GpioCtrlRegs.GPAMUX2.bit.GPIO18 = 3; // XINTF_A[0]
    GpioCtrlRegs.GPAMUX2.bit.GPIO19 = 3; // XINTF_A[1]
    GpioCtrlRegs.GPAMUX2.bit.GPIO20 = 3; // XINTF_A[2]
    GpioCtrlRegs.GPAMUX2.bit.GPIO21 = 3; // XINTF_A[3]
    GpioCtrlRegs.GPAMUX2.bit.GPIO22 = 3; // XINTF_A[4]
    GpioCtrlRegs.GPAMUX2.bit.GPIO23 = 3; // XINTF_A[5]
    GpioCtrlRegs.GPAMUX2.bit.GPIO24 = 3; // XINTF_A[6]
    GpioCtrlRegs.GPAMUX2.bit.GPIO25 = 3; // XINTF_A[7]
    GpioCtrlRegs.GPAMUX2.bit.GPIO26 = 3; // XINTF_A[8]
    GpioCtrlRegs.GPAMUX2.bit.GPIO27 = 3; // XINTF_A[9]
    GpioCtrlRegs.GPAMUX2.bit.GPIO28 = 3; // XINTF_A[10]
    GpioCtrlRegs.GPAMUX2.bit.GPIO29 = 3; // XINTF_A[11]
    GpioCtrlRegs.GPBMUX1.bit.GPIO32 = 3; // XINTF_A[12]
    GpioCtrlRegs.GPBMUX1.bit.GPIO33 = 3; // XINTF_A[13]
    GpioCtrlRegs.GPBMUX1.bit.GPIO34 = 3; // XINTF_A[14]
    GpioCtrlRegs.GPBMUX1.bit.GPIO35 = 3; // XINTF_A[15]
    GpioCtrlRegs.GPBMUX1.bit.GPIO36 = 3; // XINTF_D[15]
    GpioCtrlRegs.GPBMUX1.bit.GPIO37 = 3; // XINTF_D[14]
    GpioCtrlRegs.GPBMUX1.bit.GPIO38 = 3; // XINTF_D[13]
    GpioCtrlRegs.GPBMUX1.bit.GPIO39 = 3; // XINTF_D[12]
    GpioCtrlRegs.GPCMUX1.bit.GPIO64 = 3; // XINTF_D[11]
    GpioCtrlRegs.GPCMUX1.bit.GPIO65 = 3; // XINTF_D[10]
    GpioCtrlRegs.GPCMUX1.bit.GPIO66 = 3; // XINTF_D[9]
    GpioCtrlRegs.GPCMUX1.bit.GPIO67 = 3; // XINTF_D[8]
    GpioCtrlRegs.GPCMUX1.bit.GPIO68 = 3; // XINTF_D[7]
    GpioCtrlRegs.GPCMUX1.bit.GPIO69 = 3; // XINTF_D[6]
    GpioCtrlRegs.GPCMUX1.bit.GPIO70 = 3; // XINTF_D[5]
    GpioCtrlRegs.GPCMUX1.bit.GPIO71 = 3; // XINTF_D[4]
    GpioCtrlRegs.GPCMUX1.bit.GPIO72 = 3; // XINTF_D[3]
    GpioCtrlRegs.GPCMUX1.bit.GPIO73 = 3; // XINTF_D[2]
    GpioCtrlRegs.GPCMUX1.bit.GPIO74 = 3; // XINTF_D[1]
    GpioCtrlRegs.GPCMUX1.bit.GPIO75 = 3; // XINTF_D[0]
    EDIS;

    // XINTF总线控制器配置
    EALLOW;
    DevCfgRegs.XINTFSEL.bit.XINTF_EMB_DEV_SEL = 0; // 选择XINTF和EMIF的总线控制器
    XintfRegs.XINTCNF2.bit.XTIMCLK = 0; // 设置时钟为SYSCLKOUT
    XintfRegs.XINTCNF2.bit.CLKMODE = 0; // 设置时钟模式为XCLKOUT
    XintfRegs.XTIMING0.bit.XWRLEAD = 1; // 写操作提前一个时钟周期
    XintfRegs.XTIMING0.bit.XRDLEAD = 1; // 读操作提前一个时钟周期
    XintfRegs.XTIMING0.bit.XRDACTIVE = 2; // 读操作持续两个时钟周期
    XintfRegs.XTIMING1.bit.XWRACC = 2; // 内存写入操作的访问时间为2个XCLKOUT周期
    XintfRegs.XTIMING1.bit.XRDACC = 2; // 内存读取操作的访问时间为2个XCLKOUT周期
    XintfRegs.XTIMING1.bit.XOENSEL = 1; // 使能输出使能信号
    XintfRegs.XTIMING1.bit.ENABLE = 1; // 使能时序生成器
    EDIS;
}

// XINTF读取数据
Uint16 ReadXintfData(Uint16 *addr)
{
    Uint16 data;
    data = *addr;
    return data;
}

// XINTF写入数据
void WriteXintfData(Uint16 *addr, Uint16 data)
{
    *addr = data;
}

以上是使用dsp28335的xintf进行通信的C语言代码示例，供你参考。
