TLV320AIC3120的Beep Generator (PRB_P25)使用问题



如何使用Beep Generator (PRB_P25)使得芯片内部产生固定频率的正弦信号,驱动外接的喇叭发出固定频率的声音,目前DAC的播放已经正常调通且DAC使用的是PRB_P25数字处理模块,采样频率为16K配置如下:

Aic3120_SetPage(0);

/*Beep Generator*/

/*生成1K的sin波形,发出5s的喇叭响声*/
Aic3120_WriteReg(0x4c,0x30);
Aic3120_WriteReg(0x4d,0xfc);

Aic3120_WriteReg(0x4e,0x76);
Aic3120_WriteReg(0x4f,0x41);

Aic3120_WriteReg(0x49,0x01);
Aic3120_WriteReg(0x4a,0x38);
Aic3120_WriteReg(0x4b,0x80);

Aic3120_WriteReg(0x47,0x80);
Aic3120_WriteReg(0x48,0x80);

以上是关于该模块的配置,但是没有任何反应,望有经验者给出技术指导,谢谢!
