These parameters are characterized but not tested.
** These parameters are design targets and are not tested. No characterization data available at this time.
Note 1: Data in the Typical (“Typ”) column is at 5.0V, 25˚C unless otherwise stated. These parameters are for design guidance
only and are not tested.
2: Measurements are taken in RC Mode where CLKOUT output is 4 x TOSC.
3: See Figure 16-1 for loading conditions.
