Microphone gain behaves differently on WT41N0 (MPA 3) vs MC9596 and WT4090

Using the WT41N0 it appears the setting and reading of microphone gain (AUDIOEX_SetGain/AUDIOEX_GetGain) behaves differently on MPA 3 than MPA 2 and MPA 1.

 

I am unable to find any docs on the behavior or even a EMDK for C that covers the WT41N0.  EMDK 2.5 covers up to MC9596 (MPA 2).

 

1) Is there any place I can get documentation of the new behavior of the microphone used in the WT41N0?

 

2) Is there an EMDK for C for the WT41N0?

 

Thanks,

Any help is appreciated
