PMSM application notes, "sprc212" vs "sprc129"

This is my first post and I apologize in advance if this is not the right place to post this topic.

I am looking for PMSM application notes, for 2808, using FOC with QEP.

So far I have found "sprc212" and "sprc129". From the descriptions of the application notes I can not see any differences.

Which one is better to start with?

Thanks
