Record Gain Mute. Setting this bit mutes the input to the L/R ADCs.
Left ADC Gain. The GL[3:0] bits control the input gain on the left channel of the analog
Right ADC Gain. The GR[3:0] bits control the input gain on the right channel of the analog
8000h. This value corresponds to 0 dB gain and Mute ‘set’.
Mic Record Gain Mute. When ‘set’, mutes the input to the microphone ADC.
Mic ADC gain. The GM[3:0] bits control the input gain on the microphone source. The gain is
8000h. This value corresponds to 0 dB gain and Mute ‘set’.
