6. This specification applies to any time the FLL reference source or reference divider is changed, trim value is changed,
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
9. This specification applies to any time the PLL VCO divider or reference divider is changed, or changing from PLL disabled
