Timing Diagrams and Specifications
These parameters are characterized but not tested.
Data in "Typ" column is at 5.0V, 25 C unless otherwise stated. These parameters are for design guidance
only and are not tested.
based on characterization data for that particular oscillator type under standard operating conditions with the
device executing code. Exceeding these specified limits may result in an unstable oscillator operation
and/or higher than expected current consumption. All devices are tested to operate at "min." values with an
external clock applied to the OSC1 pin.
When an external clock input is used, the "Max." cycle time limit is "DC" (no clock) for all devices.
