3101 LINE_LP和LINE_RP输入。I2S没信号

 尊敬的TI工程师：

我3101的设置参数在下面，作为分机，外部提供2M的BCLK和32K的WCLK，设置了PLL

用模拟I2C设置的参数，设置完再读取时，MICBIAS寄存器为0X06，设置的是0x00，而且电路中MICBIAS悬空的，应该没影响

用示波器看DOUT没有波形，麻烦看下哪里设置的不对吗，附件里有电路，PLL

Write_Chip(id,0x30,0x00,0x00);//选择page0
 Write_Chip(id,0x30,0x01,0x80);//I2C reset
 Write_Chip(id,0x30,0x65,0x00);//CLOCK_div  默认PLL
 Write_Chip(id,0x30,0x66,0xA0);//PLL_IN 选BCLK 2MHz
 Write_Chip(id,0x30,0x07,0x00);//FS(ref)48K
 Write_Chip(id,0x30,0x02,0x11);//codec采样率32K = FS/1.5
 //48K = 2M*(7*7.0273)/2048
 Write_Chip(id,0x30,0x03,0x81);//PLL开 P = 1
 Write_Chip(id,0x30,0x04,0x1C);//J = 7
 Write_Chip(id,0x30,0x0B,0x07);//R = 7
 Write_Chip(id,0x30,0x05,0x03);//D = 03 实际为0.0273
 Write_Chip(id,0x30,0x06,0x64);//D = 64
 
 Write_Chip(id,0x30,0x08,0x00);//I2S从模式
 Write_Chip(id,0x30,0x09,0x30);//32位
 //模拟-->IIS
 Write_Chip(id,0x30,0x13,0x04);//MIC1LP到L-PGA
 Write_Chip(id,0x30,0x16,0x04);//MIC1RP到R-PGA
 Write_Chip(id,0x30,0x19,0x00);//偏置电压0V
 Write_Chip(id,0x30,0x0F,0x00);//0dB
 Write_Chip(id,0x30,0x10,0x00);//0dB

我怀疑没有得到正确设置, 如果时序是正常的, 可能各配置指令间还需要一定的延迟时间

但是我读出来寄存器的值都是设置值的话应该已经设置成功了吧
