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 7-5

Unimplemented: Read as ‘0’

bit 4

HFIOFR: High-Frequency Internal Oscillator Ready bit

1 = 16 MHz Internal Oscillator (HFINTOSC) is ready

0 = 16 MHz Internal Oscillator (HFINTOSC) is not ready

bit 3-2

Unimplemented: Read as ‘0’

bit 1

LFIOFR: Low-Frequency Internal Oscillator Ready bit

1 = 31 kHz Internal Oscillator (LFINTOSC) is ready

0 = 31 kHz Internal Oscillator (LFINTOSC) is not ready

bit 0

HFIOFS: High-Frequency Internal Oscillator Stable bit

1 = 16 MHz Internal Oscillator (HFINTOSC) is stable

0 = 16 MHz Internal Oscillator (HFINTOSC) is not yet stable
