Question

DFP does not describe the J-suffixed 'C552 pinout

As far as I can tell from the naming, this is the file which is supposed to cover both the non-suffixed and J-suffixed STM32C552Rxx. 

However, I can’t see any, e.g. mention of the PE2..PE5 pins which are present for the J-suffix.

I still would very much like to see the ‘C5 family covered also by the “old style” xml in the Open pin data.
