TLV320AIC3105电源模块无法开启

TLV320AIC3105输出寄存器写入上电，但是电源状态寄存器Page 0/Register 94显示电源未上电。这是什么原因？

user151383853：

这是有关低功耗应用方面的情况, 手册有这样的介绍:

As the TLV320AIC3105 is designed for low-power applications, when powered up, the device has several features powered down. A correct routing of the TLV320AIC3105 signals is achieved by a correct setting of the device registers, powering up the required stages of the device and configuring the internal switches to follow a desired route.• For more information of the device configuration and programming, refer to the TLV320AIC3105 technical documents section in ti.com (http://www.ti.com/product/TLV320AIC3105/technicaldocuments)

谢谢Airwill ，但是我已经设置过LEFT_LOP/M 的寄存器Page 0/Register 86，读出的装填显示“LEFT_LOP/M is not fully powered up”。

路由到LEFT_LOP/M/RIGHT_LOP/M的其他寄存器我也做过设置了，但是读出Page 0/Register 94显示0xc0“Left DAC/Right DAC is fully powered up,LEFT_LOP/M/RIGHT_LOP/M  output driver is powered down”。所有的寄存器我都看过好几遍了，没发现别的电源设置了。

她就是不上电，不知道还有没有别的原因。
