Data in Typical column was characterized at 5.0 V, 25C or is typical recommended value
The resulting bus clock frequency should not exceed the maximum specified bus clock frequency of the device.
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.
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.
