1 TRIM register at default value (0x80) and FTRIM control bit at default value (0x0).
2 This specification applies to any time the FLL reference source or reference divider is changed, trim value changed or changing
from FLL disabled (BLPE, BLPI) to FLL enabled (FEI, FEE, FBE, FBI). If a crystal/resonator is being used as the reference,
this specification assumes it is already running.
3 This specification applies to any time the PLL VCO divider or reference divider is changed, or changing from PLL disabled
(BLPE, BLPI) to PLL enabled (PBE, PEE). If a crystal/resonator is being used as the reference, this specification assumes it is
already running.
4 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.
5 Below D
lock minimum, the MCG is guaranteed to enter lock. Above Dlock maximum, the MCG does not enter lock. But if the
MCG is already in lock, then the MCG may stay in lock.
6 Below D
unl minimum, the MCG does not exit lock if already in lock. Above Dunl maximum, the MCG is guaranteed to exit lock.
