D FLL acquisition time 3
3 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.

4 This specification applies to any time the PLL VCO divider or reference divider is changed, or changing from PLL disabled

it is already running.
