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 OSC1 pin. When an
external clock input is used, the ‘max’ cycle time limit is ‘DC’ (no clock) for all devices.
