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.
