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

(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 to the specified steady state frequency range.
