Microphone Mute. Setting this bit mutes the MIC1 or MIC2 signal. The selection of the MIC1 or
MIC2 input pin is controlled by the MS bit in the General Purpose Register (Index 20h).
Microphone Volume Control. The GN[4:0] bits are used to control the gain level of the Micro-
phone input source to the Input Mixer. Each step corresponds to 1.5 dB gain adjustment, with
01000 = 0 dB. The total range is +12 dB to -34.5 dB gain. See Table 3 for further details.
Microphone 20 dB Boost. When ‘set’, the 20dB bit enables the +20 dB microphone boost block.
This bit allows for variable boost of 0 dB or +20 dB. Table 3 summarizes this behavior.
8008h. This value corresponds to 0 dB gain and Mute ‘set’.
