1) The minimum and maximum oscillator periods for PLL operation depend on the selected CPU clock
2) The clock input signal must reach the defined levels
3) The minimum high and low time refers to a duty cycle of 50%. The maximum operating frequency (

limited to a range of 4 MHz to 40 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. Operation at lower input frequencies is possible but is guaranteed by
design only (not 100% tested).
