except PLL. All specified values 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 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/CLKI pin. When an external clock input
is used, the “max.” cycle time limit is “DC” (no clock) for all devices.
