Data Sheet
The minimum and maximum oscillator periods for PLL operation depend on the selected CPU clock generation
mode. Please see respective table above.
The clock input signal must reach the defined levels
The minimum high and low time refers to a duty cycle of 50%. The maximum operating freqency (
drive mode depends on the duty cycle of the clock input signal.
limited to a range of 4 MHz to 16 MHz.
It is strongly recommended to measure the oscillation allowance (or margin) in the
final target system (layout) to determine the optimum parameters for the oscillator
operation. Please refer to the limits specified by the crystal supplier.
When driven by an external clock signal it will accept the specified frequency
range (see
