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).
This is the shortest pulse that is guaranteed to pass through the pin input filter circuitry. Shorter pulses may or may not be
recognized.
This is the minimum pulse width that is guaranteed to pass through the pin synchronization circuitry. Shorter pulses may or
may not be recognized. In stop mode, the synchronizer is bypassed so shorter pulses can be recognized in that case.
Timing is shown with respect to 20% V
