Pin Function Grouping

Thought for 4 sec

Thought for a moment

I’ll make the GPIO functional grouping more general by changing all port-specific groups like GPIOA/GPIOB/GPIOC/GPIOD/GPIOE to a single GPIO group, while keeping Power, Ground, Reference, and Oscillator as-is.

Done. I generalized the functional grouping so all PTA/PTB/PTC/PTD/PTE terminals now use Pin Group = GPIO.

The remaining high-level groups are now: Power, Ground, Reference, Oscillator, and GPIO; rail-specific details remain in Pin Description where useful.

Add a Section property to all pins, and apply the same value used in the Pin Group property to each pin's Section property

I’ll copy each pin’s current Pin Group value into its Section property across all 172 terminals, then spot-check representative pins from each group.

3/3 tasks completed.

Thought for a moment

Done. I added Section to the pins and set it to match each pin’s Pin Group value:

GPIO pins → Section = GPIO
Power pins → Section = Power
Ground pins → Section = Ground
Reference pins → Section = Reference
Oscillator pins → Section = Oscillator

I spot-checked representative pins from each group and confirmed Section matches Pin Group.
