are 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 oper-
ation 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.
