Left Channel Source. The SL[2:0] bits select the left channel source to pass to the ADCs for
recording. See Table 6 for possible values.
Right Channel Source. The SR[2:0] bits select the right channel source to pass to the ADCs for
recording. See Table 6 for possible values.
0000h. This value selects the Mic input for both channels.
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 source,
applied after the input mux and before the ADCs. Each step corresponds to 1.5 dB gain adjust-
ment, with 0000 = 0 dB. The total range is 0 dB to +22.5 dB gain.
Right ADC Gain. The GR[3:0] bits control the input gain on the right channel of the analog
source, applied after the input mux and before the ADCs. Each step corresponds to 1.5 dB gain
adjustment, with 0000 = 0 dB. The total range is 0 dB to +22.5 dB gain.
8000h. This value corresponds to 0 dB gain and Mute ‘set’.
