These parameters are for design guidance only and are not tested, nor characterized.
characterization data for that particular oscillator type under standard operating conditions with the device executing code.
Exceeding these specified limits may result in unstable oscillator operation and/or higher than expected current consump-
tion. 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.
