DSP6713的关于TLV320AIC23B的IIC配置

各位仁兄,本人最近用SEED公司的DSP6713的I2C0控制TLV320AIC23B的寄存器时,程序调试总出现问题,现贴出来,做过这方面的仁兄请指导一下:

#include "DEC6713.h"

   while(1){};
}

我本想通过IIC0来配置AIC23B的寄存器,使AIC23B为Bypass模式，这样就可以直接将音频信号输出来，以验证AIC23B配置的正确.可总也出不来,不知道哪位知道原因,请指教.

         0x00000000  /* RCLKCHK - Not used */
      };

请问一下高手,我要从TLV320AIC23B采集16位无符号整数数据,那么McASP的接收部分的数据形式该怎样配置?是否必须以32位进行采集?
