Bit 1 – RUNSTDBY: Run Standby

Run Standby

This bit force 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 4 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.
