(1)

After a wakeup from LPM1, LPM2, LPM3 or LPM4 the DCO frequency fDCO might exceed the specified frequency range for a few clocks

cycles by up to 5% before settling into the specified steady state frequency range.

Calculated using the box method: (MAX(–40°C to 85ºC) – MIN(–40°C to 85ºC)) / MIN(–40°C to 85ºC) / (85ºC – (–40ºC))
