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 4x PLL Ready bit

1 = 4x PLL is ready

0 = 4x PLL is not ready

bit 5

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)

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
