Bits 5:0 – CAL20M[5:0]: Calibration
These bits change the frequency around the current center frequency of the OSC20M for fine tuning.
At Reset factory calibrated values are loaded based on FREQSEL bits in FUSE.OSCCFG.

Bit 7 – LOCK: Oscillator Calibration Locked by Fuse
When this bit is set, the calibration settings in CLKCTRL.OSC20MCALIBA and
CLKCTRL.OSC20MCALIBB cannot be changed.
The Reset value is loaded from the OSCLOCK bit in the Oscillator Configuration fuse (FUSE.OSCCFG).
Bits 3:0 – TEMPCAL20M[3:0]: Oscillator Temperature Coefficient Calibration
These bits tune the slope of the temperature compensation.
At Reset factory calibrated values are loaded based on FREQSEL bits in FUSE.OSCCFG.

Bit 1 – RUNSTDBY: 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.
