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

(2) After a wakeup from LPM1, LPM2, LPM3, or LPM4, the DCO frequency f_DCO might exceed the specified frequency range for a few clock cycles by up to 5% before settling into the specified steady-state frequency range.
