FLL acquisition time3, 4
4 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.

C
Long term jitter of DCO output clock (averaged over 2 ms
interval)5
5 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 the crystal oscillator frequency increase the CJitter percentage
for a given interval.
