bit 0

Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

Unimplemented: Read as ‘0’

bit 6

SOSCRUN: SOSC Run Status bit

1 = System clock comes from a secondary SOSC

0 = System clock comes from an oscillator other than SOSC

bit 5

Unimplemented: Read as ‘0’

bit 4

SOSCDRV: Secondary Oscillator Drive Control bit(1)

1 = High-power SOSC circuit selected

0 = Low/high-power select is done via the SOSCSEL<1:0> Configuration bits

bit 3

SOSCGO: Oscillator Start Control bit

1 = Oscillator is running even if no other sources are requesting it

0 = Oscillator is shut off if no other sources are requesting it (When the SOSC is selected to run from

a digital clock input, rather than an external crystal, this bit has no effect.)

bit 2

Unimplemented: Read as ‘0’

bit 1

MFIOFS: MF-INTOSC Frequency Stable bit

1 = MF-INTOSC is stable

0 = MF-INTOSC is not stable

bit 0

MFIOSEL: MF-INTOSC Select bit

1 = MF-INTOSC is used in place of HF-INTOSC frequencies of 500 kHz, 250 kHz and 31.25 kHz

0 = MF-INTOSC is not used

Note 1: When SOSC is selected to run from a digital clock input, rather than an external crystal, this bit has no

effect.
