2.2.1 Writing the OSCLOCK Fuse in FUSE.OSCCFG to '1' Prevents Automatic Loading of Calibration Values
Writing the OSCLOCK fuse in FUSE.OSCCFG to ‘1’ prevents
the automatic loading of calibration values from the signature row. The device will
run with an uncalibrated OSC20M oscillator.
Work Around
Do not use OSCLOCK for locking the oscillator calibration value. The oscillator
calibration value can be locked by writing LOCKEN in CLKCTRL.MCLKLOCK to
‘1’ when using the OSC20M oscillator as the Main Clock
source.
