CS Module
Functional
DCO clock frequency out of specification when returning from LPM2, LPM3 or LPM4
When waking up from LPM2, LPM3 or LPM4 the first clocks generated by the DCO are not within the specified frequency range for approximately 13us (independent of the selected frequency). Any observable overshoot of the frequency is not critical for the device functionality. Frequency undershoots can be considered as additional wake-up delay because the frequency is below the target and less clocks are generated than expected. The overall impact of the clock overshoots and undershoots during stabilization is approximately 2us of additional delay.
Account for frequency undershoots as additional wake-up delay of about 2us.
