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 SOSCR: Secondary Oscillator Ready bit

If T1OSCEN =

1 = Secondary oscillator is ready

0 = Secondary oscillator is not ready

If T1OSCEN = 0:

1 = Timer1 clock source is always ready

bit 6 PLLRDY: PLL Ready bit

1 = PLL is ready

0 = PLL 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 Words

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 3-2 Unimplemented: Read as ‘0’

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 16 MHz Oscillator is stable and is driving the INTOSC

0 = HFINTOSC 16 MHz is not stable, the Start-up Oscillator is driving INTOSC
