GeneralARM Processor // GPIO // Physical Pin Pin

Hey mods, move this message to a better place and I'll still love CodeProject. I couldn't find this topic listed.

Anyway, I am studying the ARM processor.

Doing the Stellaris LaunchPad, which I think is no longer sold.

The schematic I have here says that Pin 29 (in this case) is actually GPIO port F, bit 1.

I'll try to post a screen cap of the part of the schematic if it would help.

For now, my question is: Who made Pin 29 to be that bit on that port ?

Is it hard-wired in the ASIC ? Or is there a pin-assigning circuit in the chip which will let firmware do the choosing ?

My homework before posting this question included Google, Bing, and a few sites that didn't really answer the question.

The ARM site itself is currently overwhelming me; i.e., I would imagine the answer is probably on some page there, or some PDF file; now to guess where.

Were you affected by the geomagnetic storms this past weekend?
Communication disruptions, electrified pipes, random unexplained blue-screens in Windows - the list of effects is terrifying.
