2.2.3 Frequency Drift of 16/20 MHz Oscillator at High Supply and High Temperature
The frequency of the internal 16/20 MHz oscillator may drift out of the given specifications when the oscillator is disabled or stopped when VDD is above 4.5V and the temperature is above 85°C.
Work Around
Keep the oscillator running by setting the Run Standby (RUNSTDBY) bit to
‘1’ in the 16/20 MHz Oscillator Control A (CLKCTRL.OSC20MCTRLA)
register and avoid using Power-Down sleep mode.
