* 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.
Note1: Measurements are taken in RC Mode where CLKOUT output is 4 x TOSC.
