When the time and output level configured at AGCOFFTIME goes under AGC_MIN, compression turns OFF.
AGCOFFTIME is configured at &h22[2:0].
Default = 0
Select Address
&h22 [ 2：0 ]
Operation Description
R_RATE is the configuration of the speed of volume increase. It is configured at &h23[3:0].

Select Address
&h23 [ 3：0 ]
Operation Description
4-11. Post-Scaler
When outputting 28bit-wide data computed by the DSP, the first 4 bits that were added on at input as overflow margin are
removed before the output; however, if the post-scaler is used when the DSP performs a variety of calculations and adjusts
the level for output, the level adjustments are made simpler.
