pin currents and analog in

Hello community,

is there any example out there how to use the analog in pins?

In the doc

NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH. DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.

So how to wire up dome simple potentiometer ?

And what are the available currents s(sink/source) on the normal io pins?

Sunny greetings

Stefan
