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.
Do not use OSCLOCK for locking the oscillator calibration value. The
oscillator calibration value can be locked by writing LOCK in CLKCTRL.OSC20MCALIBB
to ‘1
’.
