D FLL acquisition time 2
2 This specification applies to any time the FLL reference source or reference divider is changed, trim value changed or changing
from FLL disabled (FBELP, FBILP) to FLL enabled (FEI, FEE, FBE, FBI). If a crystal/resonator is being used as the reference,
this specification assumes it is already running.

D DCO output clock long term jitter (over 2mS interval) 3
3 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
BUS.
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise injected
into the FLL circuitry via VDD and VSS and variation in crystal oscillator frequency increase the CJitter percentage for a given
interval.
