tested.
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 con-
sumption. All devices are tested to operate at “min” values with an external clock applied to OSC1 pin. When an external
clock input is used, the “max” cycle time limit is “DC” (no clock) for all devices.
These parameters are characterized but not tested.
