[SOLVED] Does attaching sleep mode interrupt remove interrupt on same pin?

Actually looking at this a little more, I think I want the sleep trigger to be CHANGE - I have an external pullup circuit and was having trouble getting the device to wake sometimes (not passing the trigger voltage), then found this old post: Having trouble using Sleep() with wakeUpPin where @peekay123 mentions that pinMode is set to PULLDOWN for RISING, PULLUP for FALLING, and INPUT for change. Where is this kind of stuff documented? Should I put in a PR to the firmware docs?
