Gregory, Very useful piece of info you gave. Can you please tell me how you get a copy of the captioned booklet? Does it come out regularly?? Can it be seen on Mchip's web site (I couldn't find it)? Asking them to send a copy is almost impossible. Asking them to send regularly - haha, you have to be crazy, don't even think about it. Thanks.
