Pin Grouping by Function


There are currently 8 pin groups, while Terminal Order applies to individual pins, not whole groups. Should I:
  1. Assign each group a shared order (Power=1 … Ground=10), or
  2. Keep unique ordering for all 32 pins and use 1–10 only as section priority?
I’ll alternate the remaining groups between Left and Right, with Power Top and Ground Bottom.
Use option 2: keep unique pin ordering, with section priority from 1 through 10 and Ground at 10.
I’ll apply globally unique pin ordering in section-priority order: Power first, then Clock, Control, Debug, GPIO groups, and Ground last. Power/Ground will use Top/Bottom, with the other groups alternating Left and Right.
Applied and verified unique terminal ordering across all 32 pins:
  • Power: first, Top
  • Ground: last, Bottom
  • Remaining groups alternate between Left and Right
  • Orders progress by section priority from Power through Clock, Control, Debug, GPIOA/B/D, then Ground
