Note 1:
These parameters are characterized but not tested.
Data in "Typ" column is at 5V, 25˚C unless otherwise stated. These parameters are for design guidance
only and are not tested.
These parameters are asynchronous events not related to any internal clock edges.
Measurements are taken in RC Mode where CLKOUT output is 4 x TOSC.
