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/CLKIN pin. When an external clock input is used, the "max." cycle time
limit is "DC" (no clock) for all devices.
