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.

Master clock (MCLK) = 256 x Fs
Bits [5:2] — I2SFS3-I2SFS0
I2S 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 36 for a
complete listing of available sampling rates. All combinations of I2SFS[3:0] not in Table 36 are not valid.

Bits [1:0] — I2SFM1-I2SFM0
I2S Format. These two bits select the I2S interface format. Both 16-bit and 20-bit data formats are supported. The
default format is 20-bit I2S.

ADC VOLUME CONTROL REGISTER (Page 2, Address 01h)
The ADC volume control register controls the independent programmable gain amplifiers (PGA's) on the left and
right channel inputs to the audio ADCs of the TSC2301. The gain of these PGAs can be adjusted from
-40 dB to 20 dB in 0.5-dB steps. The ADC inputs can also be hard-muted, or internally shorted to VCM so that no
input signal is seen.
The ADC volume control register is formatted as follows:
