Using Purepath to implement ADC3101 PRB2 in miniDSP

Hi,

I'm trying to program mini DSP in ADC3101 because I need click remove function adding on PRB2.

 

So, I nned to change to use miniDSP instead of PRB2.

Now, I'm trying to just implement PRB2 by using Purepath.

 1. Choose Framework ADC3x01App4x_1

2. Choose MonoDec4xIn_1 with AGC enable

3. cascade 5 biquad

4 connect to MonoI2S_out.

 

However, it seems to works as different as PRB2.

Here is the question,

1.While choosing  MonoDec4xIn_1, does it means that I'm choosing "Decimation Filter A" and I don't have to add any component on Purepath GDE?

2. Does the AGC setting in MonoDec4xIn_1 is in the end of the 5 biquad Filtesr? Just like PRB2 or it is in from]nt of all?

Thanks for your help first.
