* 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 5V, 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: Refer to Figure 19-2 for load conditions.
