i want to understand how the LPC pins working. so i want to know the step between a register and the output/input port. i didnÂ´t want to know about the software i know how i configure ports! I want to know the hardeware. I couldnÂ´t find anythink about it in the usermanual or somewhere else. it would be very helpful if someone know where i can find some schematics. thanks a lot.

You are trying to solve a particular problem? What problem? Also which LPC device? There are significant differences in pin usage for each family of LPC devices. Are you using an LPCXpresso board? If so, which board? Owners of LPCXpresso boards can register for support and then download the schematics for that board from the Embedded Artists site: http://www.embeddedartists.com/support/overview
