AVC Attack Rate
This is the rate at which the AVC will apply attenuation to the
signal to bring it to the threshold level. AVC Attack Rate is
programmable. To use a custom rate, use the formula below
to convert from dB/S to hex value:
Hex Value = (1 - (10^(-(Rate_dBs/( 20*SYS_FS)))) * 2^19
where, SYS_FS is the system sample rate configured in
CHIP_CLK_CTRL register.
Example values:
0x28 = 32dB/s
0x10 = 8dB/s
0x05 = 4dB/s
0x03 = 2dB/s

AVC Decay Rate
This is the rate at which the AVC releases the attenuation
previously applied to the signal during attack. AVC Decay
Rate is programmable. To use a custom rate, use the formula
below to convert from dB/S to hex value:
Hex Value = (1 - (10^(-(Rate_dBs/( 20*SYS_FS)))) * 2^23
where, SYS_FS is the system sample rate configured in
CHIP_CLK_CTRL register.
Example values:
0x284 = 32dB/s
0xA0 = 8dB/s
0x50 = 4dB/s
0x28 = 2dB/s
