28335的MCBSP中有FIFO增强功能嘛？

请问TMS320F28335的多通道缓冲接口MCBSP中有FIFO增强功能嘛？我买的教材上有讲MCBSP的FIFO增强功能，但TI官方给的MCBSP头文件中没有定义FIFO的寄存器，什么情况呢？

您好，Joey Mao：

      谢谢，我买的《TMS320 F28X源码解读》这本书中（170页）说MCBSP中有FIFO增强功能，也有MCBSP用FIFO通讯的例子（184页），是书中写错了嘛？

你看的书讲的是比较老的C2000芯片，如F281x, 用的是MCBSP type0.

后续新的芯片，如F2833x, F2806x的MCBSP是type1的，把FIFO移除了。
