AM623: Does AM623x support DDR CLOCK Spread Spectrum?

Tool/software:

Hi, Expert

As title description, this thread is double confirm to make sure I do not miss understanding.

Question from customer, they want to know, Does AM623x support DDR CLOCK Spread Spectrum?

Already reference many threads.

Question : 

1. We do not support DDR CLOCK Spread Spectrum, am I correct?

2. What's the DDR PLL?

3. Default setting for AM62x, DDR CLOCK Spread Spectrum is disable, am I correct?

Thank you.
