Completed the exhaustive pass for the remaining GPIO ports and special interfaces. GPIO ports B/C plus D/E/F/G/H/I/Z-style pins are grouped, and DSI, USB, JTAG/SWD, reset/control, DDR data/control/reference, and specialized grounds were assigned to single primary functional groups.

Suggested next steps:

I’ll normalize the pin groups to generic labels, audit all terminals for missing group/section properties, then reorganize the symbol positions by section.

The audit found duplicate supply terminals where only the first instance had been grouped; I corrected those scoped VDD/VDDCORE/VDDQ/VSS terminals and normalized GPIOA/B/C to generic GPIO.

Completed the symbol cleanup: normalized GPIO labels to generic GPIO, fixed duplicate supply pins, assigned the remaining ungrouped terminals, and added section-based symbol positioning anchors for Power/GPIO/Clock/DDR/USB/Debug/Control regions. Final audit reports none found for terminals missing Pin Group or Section.
