器件型号：TAS2770您好！
我们有一个 TAS2770音频放大器连接到 Nordic Nrf52832 µC 的 I2S 输出。
但扬声器输出上没有任何内容(所连接的示波器屏幕上呈绿色显示)
我已经配置了 nRF52、可以看到 I2S 信号(FSYNC 为黄色、LBCLK 为蓝色、SDIN 为紫色)。
我写入 TAS2770寄存器：
I2C0_WriteReg (TAS2770_address、TAS2770_BOOKCTL_PAGE、0)；//第0页
I2C0_WriteReg (TAS2770_address、TAS2770_BOOKCTL_REG、0)；//书籍0
I2C0_WriteReg (TAS2770_address、TAS2770_SW_RST、1)；//软件复位
NRF_DELAY_ms (1)；
I2C0_WriteReg (TAS2770_address、TAS2770_TDM_CFG_REG0、0x06)；// 48kHz、自动 TDM 关闭、 帧从低到高开始
I2C0_WriteReg (TAS2770_address、TAS2770_TDM_CFG_REG1、0x02)；//偏移= 1、在 SBCLK 上升沿上同步
I2C0_WriteReg (TAS2770_address、TAS2770_TDM_CFG_REG2、0x30)；// TDM 立体声、字= 16位、帧= 16位
I2C0_WriteReg (TAS2770_address、TAS2770_TDM_CFG_REG3、0x10)；//右侧通道= TDM 插槽1、左侧通道= TDM 插槽0
I2C0_WriteReg (TAS2770_address、TAS2770_Play_CFG_REG0、0x01)；// 11.5dB 增益5.32Vpk
I2C0_WriteReg (TAS2770_address、TAS2770_CLK_CFF、0x08)；// sblk 与 FS 的比率= 32
I2C0_WriteReg (TAS2770_address、TAS2770_PWR_CTRL、0)；//在启用 I、V 的情况下启动音频回放
是否存在不良的配置？

寄存器0x77在0x17读取、因此 FS_RATE _V =错误条件。 为什么会出现此故障？ 它是如何触发的？
感谢你的帮助。
