R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 23-2 Unimplemented: Read as ‘0’
bit 1-0 FNOSC<1:0>: Initial Oscillator Group Selection on POR bits
00 = Fast RC Oscillator (FRC)
01 = Fast RC Oscillator (FRC) divided by N, with PLL module
10 = Primary Oscillator (HS,EC)
