i´ve recently seen the update to 9 axis (https://github.com/synthetos/g2/wiki/9-Axis-UVW-Operation) but i can´t find any information how to connect 3 new motors to the board…will there be any updates to the pinout?

Evening,
im currently at the state to directly connect a DRV8825-driver to an arduino due board. This is my current state:

based on

https://github.com/synthetos/g2/wiki/Arduino-DUE-Pinout-for-g2core

But i cant get a grasp on the microstepping connections. m1ms0 and m1ms1 are clear but whats with m1ms2. where is it comming from?
Basend on the information from https://www.pololu.com/product/2133 i assume ms2 needs to be connected separately. Is that correct?

Furtermore is my understanding that the output for m1vref is only for measurements and must not be connected. Is that correct?

Hints are appreciated
