Property: Configuration Change Protection
Bit 7

Bit 1 – RUNSTDBY Run Standby
This bit forces the oscillator ON in all modes, even when unused by the system. In Standby Sleep mode
this can be used to ensure immediate wake-up and not waiting for oscillator start-up time.
When not requested by peripherals, no oscillator output is provided.
It takes four oscillator cycles to open the clock gate after a request but the oscillator analog start-up time
will be removed when this bit is set.
