†† These parameters are asynchronous events not related to any internal clock edge.
OSC1
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.
Measurements are taken in RC Mode where CLKOUT output is 4 x T
