PIC16F18876 datasheet OSCTUNE
The PIC16F18876 datasheet Rev E (Latest on the website) is obviously goofed up on the OSCTUNE register. I would attach it in-line, but I am not allowed. We will see if it allows me to attach the clip from the datasheet...
1st, according to the simulator, it boots up agreeing with the datasheet, with a value of "0b100000". I assume it would boot up with the center frequency as the default... So, is it booting up at the center frequency, or the minimum frequency? Normally the tuning just acts as a 2's compliment number with 0 being the center frequency.
Beyond that, obviously, nobody proof read the tuning bits on this page!
