13 years agoA good place to look is the Pin Information File for the specific device you're using (either pdf or xls format). Besides listing the specific pinout for the device there are a few pages near the end of each document that list and describe each of the "special purpose" pins like VCCIO, VCCINT, configuration pins, etc. It tells you how to connect each one, which ones are dual-purpose, how to connect the ones you're not using, etc. Invaluable information all in one place.
