One thing that favorably impresses me about MicroChip documentation is that the PDF files have embedded text in them. The PDF standard, such as it is, allows one to photograph a page of paper, thumb prints, fly specks and all, and call that an electronic document. You can use OCR on it if the scan was good, but it is usually not worth going to all that extra trouble. Thank you.
