* These parameters are characterized but not tested.
** These parameters are design targets and are not tested. No characterization data available at this time.
† 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.
Note 1: Measurements are taken in RC Mode where CLKOUT output is 4 x Tosc.
2: Please refer to Figure 12-1 for load conditions.
