TAS5825M配置完成之后上电能输出,一段时间过后就没有输出,此时查看寄存器0x68的值变成了0x01(Sleep)
配置顺序按照手册上配置;
1. Configure ADR pin with proper setting for I2C device address.
2. Bring up power supplies (it does not matter if PVDD or DVDD comes up first).
3. Once power supplies are stable, bring up PDN to High and wait 5ms at least, then start SCLK, LRCLK.
4. Once I2S clock are stable, set the device into HiZ state and enable DSP via the I2C control port.
5. Wait 5ms at least.Then initialize the DSP Coefficient, then set the device to Play state
6. The device is now in normal operation.
配置完成之后能正常工作,一段时间(随机,可能是几秒,可能是几十秒)后0x68的值变成了0x01(Sleep)
