注：片选有效时，从机会自动加载SPI0_S_PRE的预置值到发送移位缓冲区，所以最好可以在片选
|
||||||
|
有效前向SPI0_S_PRE寄存器写入预发值，或者在主机端丢弃首个接收字节，发送时注意主机会先
|
||||||
|
取走SPI0_S_PRE里面的值产生一个S0_IF_BYTE中断。
|
||||||
|
如果片选从无效到有效，从机首先进行发送的话，最好把输出的首字节放到SPI0_S_PRE寄存器中；
|
||||||
|
如果已经处于片选有效的话，数据数据使用SPI0_DATA就可以

* Description : CH554模拟USB Module(CH554),厂商自定义接口设备，需要安装驱动，
|

|
驱动搜索CH37XDRV或者安装ISPTool会自动安装该设备类驱动，该设备类除了控制传输外，还是直插端点2批量上下传和端点1
|
||||||
|
中断上传，可以通过372DEBUG.EXE获取其他USB调试工具进行收发数据演示
