Hi David,

Usually when a pin says N/C it means that there are more pins on the package
than die bonding areas to be connected.

Sometimes it is a reserved pin and the manufacturer does not wish to support
in the general population.

You would have to look at the die bonding docs to get the complete picture.

I work at Freescale Semi. And I know from our products this is usually the
case in many type of products.

Terry
