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 edges.

Note 1:

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

Note: Refer to Figure 11-1 for load conditions.
