Not Connected Pin
Such pins are not bonded with the silicon. Although any potential at
these pins will not impact the device it is recommended to leave them
unconnected. NC pins might be used for additional functionality in later
versions of the device. Leaving them unconnected will guarentee
hardware compatibility to later device versions.
