bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
q = depends on condition
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
bit 7
PLLRDY: PLL Run Status bit
1
= System clock comes from 4xPLL
0
= System clock comes from an oscillator, other than 4xPLL
bit 6
SOSCRUN: SOSC Run Status bit
1
= System clock comes from secondary SOSC
0
= System clock comes from an oscillator, other than SOSC
bit 5
Unimplemented: Read as ‘0’.
bit 4
MFIOSEL: MFINTOSC Select bit
1
= MFINTOSC is used in place of HFINTOSC frequencies of 500 kHz, 250 kHz and 31.25 kHz
0
= MFINTOSC is not used
bit 3
SOSCGO(1): Secondary Oscillator Start Control bit
1
= Secondary oscillator is enabled.
0
= Secondary oscillator is shut off if no other sources are requesting it.
bit 2
PRISD: Primary Oscillator Drive Circuit Shutdown bit
1
= Oscillator drive circuit on
0
= Oscillator drive circuit off (zero power)
bit 1
MFIOFS: MFINTOSC Frequency Stable bit
1
= MFINTOSC is stable
0
= MFINTOSC is not stable
bit 0
LFIOFS: LFINTOSC Frequency Stable bit
1
= LFINTOSC is stable
0
= LFINTOSC is not stable
Note 1:
The SOSCGO bit is only reset on a POR Reset.
