   i haven't shown you the best part yet
   it's buried on page 1451 of a 1475 page datasheet

   read every single footnote carefully

   what they say (and partly, don't say) is: if you inject more than +2000, -500 microamps into most of its IO pads, the device gains an intenal short to ground

   the only way to avoid this is resistors on basically every pin

   this happened because the ESD structures were too expensive to buy from TSMC and the startup Luminary Micro designed their own
