register 82, bit D7 and page 1 / register 47, bit D7. Disabling the MIC PGA sets the gain to 0 dB. Muting
the ADC causes the digital output to mute so that the output value remains fixed. When soft-stepping is
enabled, the CODEC_CLKIN signal must stay active until after the ADC power-down register is written, in
order to ensure that soft-stepping to mute has had time to complete. When the ADC POWER UP flag is
no longer set, the CODEC_CLKIN signal can be shut down.
