Set command sets the handsfree RX AGC value tuning
Parameter:
<agc_static_gain>
<agc_static_gain>
<agc_static_gain>
<agc_static_gain>
precompressor static gain. This is the gain applied to the input samples
when static gain is enabled. Meaningful Range is 0x2000 to 0xFFFF.
Value(agc_static_gain) = 8192
∗
10^(X/20) : X range is 0 to 18 dB.

pre-compressor gain selection flag. Write 0xFFFF to enable adaptive
gain (static gain disabled). Write 0x0000 to enable static gain (adaptive
gain disabled).
Meaningful value is just 0x0000 or 0xFFFF.
<agc_exp_thres>
<agc_exp_thres>
<agc_exp_thres>
<agc_exp_thres>
expansion threshold. This is the energy threshold of the input under
which expansion is applied. This parameter must be less than
agc_compr_thres.
Meaningful range is 0x0 to 0x2580. Write 0 to disable the expander.
Value(agc_exp_thres) = 128
∗
(X+75) : X range is -75 to 0 dBm0mu
<agc_exp_slope>
<agc_exp_slope>
<agc_exp_slope>
<agc_exp_slope>
expansion slope. This is the slope of the expander gain when expansion
is applied. Meaningful range is 0xFF01 to 0xFFF6.
Value(agc_exp_slope) = 256 * X : X range is -0.04 to -0.996.
<agc_compr_thres>
<agc_compr_thres>
<agc_compr_thres>
<agc_compr_thres>
compression threshold. This is the energy threshold of the input above
which compression is applied. Meaningful range is 0x0 to 0x2580. This
parameter must be greater than agc_exp_thres.
Value(agc_compr_thres) = 128
