Connect 4MEMs Mics to STM32N6 MDF1 interface

Hi ST Community,

I'm working on a custom board with STM32N6, and I plan to connect 4 MEMs microphones ( MPN: MP23DB01HPTR) to MDF1 interface. From my understanding, I need to use 4 instances ( Instance 0,1,2,3).

Here is my Mics schematic :

How should I configure the following MDF1 parameters in STM32CubeIDE ?

1. SITF0, SITF1, SITF2, SITF3 ?

2. Number of interleave ? 

How many CLK pins is required ?

I am hopping to use the following configuration ( one clock pin and two data lines), but not sure how it can be done ?
