Peripheral operating requirements and behaviors  
6. This specification applies to any time the FLL reference source or reference divider is changed, trim value is changed,  
DMX32 bit is changed, DRS bits are 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.  
7. Excludes any oscillator currents that are also consuming power while PLL is in operation.  
8. This specification was obtained using a Freescale developed PCB. PLL jitter is dependent on the noise characteristics of  
each PCB and results will vary.  
9. 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.
