And...funny note. Thanks to a friend I managed to get a look at the start of that CC article. The wording in it was so similar to the app note, I couldn't understand how they were written by different people. So...I had another look. Turns out the app note was written by the same author as the CC article, but someone updated the app note summary and then changed the author tag to his own. Odd.
