We are implementing MCM(Miscellaneous Control Module) on the S32K platform.

Specific Technical Questions:

By default, it is set to round-robin. If I change it, what impact will it have? How do I test it?

Hello,

You can find the explanation in reference manual:

As the register field express, it is slave access priority on M7 core.

Either you will use round robin, or you will define priorities for slaves for M7 access.

As ARM manual express:

You can see it as backdoor access to the core from other masters.

Best regardsm

Peter
