In the schematic you can see that two application processors are communicating via ethernet interface.
They are using MAC TO MAC communication.
Here RMII is used . One processor is SAMA5D27 from Microchip and the other is from NXP(S32K148.).
Ref designator of ethernet section of SAMA527 is U59D and this processor is working in 3.3V domain
and the reference designator of other processor is U19C and U19D.
Since they are working in different voltage levels there is a level translator used in between them(U16 and U15).
May I know my signal flow is proper between two processors and also the selection of direction of level shifters.
