ADuCM320 footprint


In the ADuCM320 EVB schematics, I've found several not-connected balls e.g. H7, H5 ea. (see below)

In the ADuCM320 datasheet, at the footprint description section, all these not-connected balls don't exist at all!

E.g. ball H7 is not exist ea...

The problem is that I've used the area under these "ghost balls" for via fan-out. This means that if these balls really exist, a short between them and the vias could happened...

Could you please clarify what are these balls? Are they reall exist?
