TSC2301 Audio Control Register (Page 2, Address 00H)
The audio control register of the TSC2301 controls the digital audio interface, the microphone preamp gain, the
record multiplexer settings, and the ADC highpass filter pole. This register determines which ADC high pass filter
response is selected, as well as which audio inputs are connected to the stereo ADCs. The gain of the MIC input
(0 to 12 dB) is also selected. This register is also used to tell the data converters the frequency of MCLK, along
with the frequency of LRCLK (ADC and DAC sample rates). The format of the audio data is also selected.
The audio control register is formatted as follows:

Bits [15:14] — HPF1-HPF0
ADC High Pass Filter. These two bits select the pass-band for the high-pass filter or disable the filter. The default
state of the filter is enabled, with -3-dB frequency at 0.000019xFs.
