1) The minimum and maximum oscillator periods for PLL operation depend on the selected
CPU clock generation mode. Please see respective table above.
2) The clock input signal must reach the defined levels V
IL and VIH2.

Memory Cycle Variables
The timing tables below use three variables which are derived from the BUSCONx registers and
represent the special characteristics of the programmed memory cycle. The following table
describes, how these variables are to be computed.
