I'm a bit confused with regard to configuring the comparator on a '628 to
use the internal reference.

The manual shows only one configuration using the internal ref - using both
comparators. I really only want to use, and use the other ports as digital.

It LOOKs like I can do this by using comparator 2, and then setting up the
voltage reference to output on the RA2 pin (which is one of comparator
2's  inputs.

Do I have that right?
