Bits [9:8] — MICG1-MICG0
Microphone Preamp Gain. These two bits select the gain of the microphone input channel. The gain of the
microphone input channel can be 0 dB, +6 dB, or +12 dB. The default gain of the microphone input channel is 0
dB.

Bits [7:6] — MCLK1-MCLK0
Master Clock Ratio. These two bits select the ratio of the audio master clock frequency to the audio sampling
frequency. The ratio can be 256 Fs, 384 Fs, or 512 Fs. The default master clock frequency is 256 Fs.

S Sample Rate. These bits tell the internal PLL what the audio sampling rate is so that it provides the proper
clock rate to the data converters and the digital filters. The default sample rate is 48 kHz. See Table 30 for a
complete listing of available sampling rates. All combinations of I2SFS[3:0] not in Table 30 are not valid.
