Data in typical column was characterized at 3.0 V and 5.0 V, 25 °C or is typical recommended value.
This parameter is characterized and not tested on each device.
This specification applies to any time the FLL reference source or reference divider is changed, trim value changed or
changing from FLL disabled (FBILP) to FLL enabled (FEI, FBI).
