It was once stated by someone with a certifiable IQ that boggles the mind, "There is nothing new in the universe". On a more micro scale, many issues we face as we try to get tiny little black plastic blocks to do what we want them to, using resources available, we have to realize that many of our challenges have been faced and conquered in the past. I try to make it a habit to search forums for clues, or out-right answers before posting questions. Not to discourage anyone from creating a new post, but when effective answers don't seem to be forthcoming, maybe as a second resort, do a search. Don't forget, this is not the only PBP forum (ME Labs, the creator of PBP, has their own forum -- though not as popular -- at http://support.melabs.com).

I faced some programming challenges in the past using newer PIC chips with Peripherals not dealt with by standard PBP commands. My solution was to familiarize myself with the Microchip Data Sheets, and manipulate the registers manually; which PBP competently allows me to do. I have successfully done what you're struggling with, but not with magic PBP commands. I don't know how to answer or contribute to this thread, because how I accomplished things cannot easily be transferred in a simple post. Try doing Forum searches, varying key search words and phrases. It will probably surprise you just how many different ways folks in the past have fought your struggles, and the solutions they found. Both sites are good at keeping older legacy posts available. Good luck!
