Whilst getting my head around the port numbering and priorities etc for various chip packages I noticed a numbering oddity :

This is probably a stupid question and I have clearly missed something obvious but why aren't there ports covering the range XnD44 - XnD48?

And or why would it be numbered in that way :?

Seems to just not be implemented yet... maybe they plan to include it in a future release or update...

It says SPARE assuming it means extra pin not needed. Maybe it was easier to route to the other pins so they skipped those heh...

Would be nice for a real answer tho heh

And also Xn59..60
