* 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 edge.
Note 1: Measurements are taken in RC mode where CLKOUT output is 4 x TOSC.
