T1OSCR PLLR OSTS HFIOFR HFIOFL MFIOFR LFIOFR HFIOFS
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared 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 PLLR 4xPLL Ready bit
1 = 4xPLL is ready
0 = 4xPLL is not ready
bit 5 OSTS: Oscillator Start-up Timer 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)
bit 4 HFIOFR: High-Frequency Internal Oscillator Ready bit
1 = HFINTOSC is ready
0 = HFINTOSC is not ready
bit 3 HFIOFL: High-Frequency Internal Oscillator Locked bit
1 = HFINTOSC is at least 2% accurate
0 = HFINTOSC is not 2% accurate
bit 2 MFIOFR: Medium-Frequency Internal Oscillator Ready bit
1 = MFINTOSC is ready
0 = MFINTOSC is not ready
bit 1 LFIOFR: Low-Frequency Internal Oscillator Ready bit
1 = LFINTOSC is ready
0 = LFINTOSC is not ready
bit 0 HFIOFS: High-Frequency Internal Oscillator Stable bit
1 = HFINTOSC is at least 0.5% accurate
0 = HFINTOSC is not 0.5% accurate
