Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
â1â = Bit is set
U = Unimplemented bit, read as â0â
â0â = Bit is cleared
x = Bit is unknown

bit 1
bit 0
Unimplemented: Read as â0â
SOSCRUN: SOSC Run Status bit
1 = System clock comes from a secondary SOSC
0 = System clock comes from an oscillator other than SOSC
Unimplemented: Read as â0â
SOSCGO: Oscillator Start Control bit
1 = Oscillator is running, even if no other sources are requesting it
0 = Oscillator is shut off, if no other sources are requesting it (When the SOSC is selected to run from
a digital clock input, rather than an external crystal, this bit has no effect.)
Unimplemented: Read as â0â
MFIOFS: MF-INTOSC Frequency Stable bit
1 = MF-INTOSC is stable
0 = MF-INTOSC is not stable
MFIOSEL: MF-INTOSC Select bit
1 = MF-INTOSC is used in place of HF-INTOSC frequencies of 500 kHz, 250 kHz and 31.25 kHz
0 = MF-INTOSC is not used
