本程序是对MCBSP进行操作,通过MCBSP接口把数据送给AIC23,让AIC23实现放音功能.-this pro. is to operate on the mcbsp on vc5402,via mcbsp the data are translated to AIC23,WHICH can play sound.

mcbsp实例，在多帧模式下，使用采样率发生器同步帧，将McBSP配置为数字环回模式与32位数据传输格式-mcbsp instance, in the multi-frame mode, the sample rate generator synchronization frame, the McBSP configured as a digital loopback mode
