Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
u = Bit is unchanged
‘1’ = Bit is set
x = Bit is unknown
‘0’ = Bit is cleared
-n/n = Value at POR and BOR/Value at all other Resets
q = Conditional
bit 7
T1OSCR: Timer1 Oscillator Ready bit
If T1OSCEN = 1:
1= Timer1 oscillator is ready
0= Timer1 oscillator is not ready
If T1OSCEN = 0:
1= Timer1 clock source is always ready
bit 6
bit 5
PLLR 4x PLL Ready bit
1= 4x PLL is ready
0= 4x PLL is not ready
OSTS: Oscillator Start-up Time-out Status bit
1= Running from the clock defined by the FOSC<2:0> bits of the Configuration Word 1
0= Running from an internal oscillator (FOSC<2:0> = 100)

HFIOFR: High Frequency Internal Oscillator Ready bit
1= HFINTOSC is ready
0= HFINTOSC is not ready
HFIOFL: High Frequency Internal Oscillator Locked bit
1= HFINTOSC is at least 2% accurate
0= HFINTOSC is not 2% accurate
MFIOFR: Medium Frequency Internal Oscillator Ready bit
1= MFINTOSC is ready
0= MFINTOSC is not ready
LFIOFR: Low Frequency Internal Oscillator Ready bit
1= LFINTOSC is ready
