Reset value is ‘0’ when Two-Speed Start-up is enabled and ‘1’ if disabled.
Default output frequency of INTOSC on Reset (4 MHz).
When the SOSC is selected to run from a digital clock input, rather than an external crystal, this bit has no
effect.
Unimplemented: Read as ‘0’
SOSCRUN: SOSC Run Status bit
1 = System clock comes from secondary SOSC
0 = System clock comes from an oscillator other than SOSC
Unimplemented: Read as ‘0’
SOSCDRV: SOSC Drive Control bit
1 = T1OSC/SOSC circuit oscillator drive circuit selected by Configuration bits, CONFIG2L<4:3>
0 = Low-power T1OSC/SOSC circuit is selected
SOSCGO: Oscillator Start Control bit
1 = Turns on the oscillator, even if no peripherals are requesting it.
0 = Oscillator is shut off unless peripherals are requesting it
PRISD: Primary Oscillator Drive Circuit shutdown
1 = Oscillator drive circuit on
0 = Oscillator drive circuit off (zero power)
Unimplemented: Read as ‘0’
