AM3352 SPI Standard

The AM335X McSPI has selectable clock phase and clock polarity per chip select. You can see details in section 24 of the AM335X TRM Rev. J and section 5.11 of the AM335X Datasheet Rev. F.

Does it mean AM3352 is not compatible with Motorola Format ?

Can you describe what format exactly you are looking for?

Yes, this is supported.
