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 SOSCEN = 1:

= Secondary oscillator is ready

= Secondary oscillator is not ready

If SOSCEN = 0:

1 =

Timer1 clock source is always ready

bit 6

Unimplemented:

Read as ‘0’

bit 5

OSTS:

Oscillator Start-up Time-out Status bit

= Running from the clock defined by the FOSC<2:0> bits of the Configuration Word 1

= Running from an internal oscillator (FOSC<2:0> = 100)

bit 4

HFIOFR:

High-Frequency Internal Oscillator Ready bit

= HFINTOSC is ready

= HFINTOSC is not ready

bit 3-2

Unimplemented:

Read as ‘0’

bit 1

LFIOFR:

Low-Frequency Internal Oscillator Ready bit

= LFINTOSC is ready

= LFINTOSC is not ready

bit 0

HFIOFS:

High-Frequency Internal Oscillator Stable bit

= HFINTOSC 16 MHz Oscillator is stable and is driving the INTOSC

= HFINTOSC 16 MHz is not stable, the 12 MHz Start-up Oscillator is driving INTOSC
