The recommended power-up sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper initialization of the device.
To configure the TLV320AIC23BIPWRQ1 for stereo audio, set the STEREO bit in the Audio Interface Control Register (AIC23_REG_04) to '1'. This enables stereo mode and allows for independent left and right channel audio processing.
The TLV320AIC23BIPWRQ1 supports clock frequencies up to 50 MHz. However, the recommended clock frequency is 12.288 MHz for optimal performance.
The TLV320AIC23BIPWRQ1 has a built-in microphone bias voltage generator. To enable it, set the MICBIAS bit in the Analog Control Register (AIC23_REG_02) to '1'. The microphone bias voltage can be adjusted using the MICBIAS_LEVEL bits in the same register.
The NOISE_GATE bit in the Analog Control Register (AIC23_REG_02) enables or disables the noise gate function. When set to '1', the noise gate function is enabled, which helps to reduce noise and hiss in the audio signal.
