Following is the logic and the way how to find such information in Marlin sources:

1. Identify the `MOTHERBOARD` in the relevant `Configuration.h`
2. Find it in `boards.h`
3. Then scroll up in `boards.h` to see which is the leading MCU type
4. Find the `pins_XXX.h` in the relevant folder of the MCU type
