1)
The CLKOUT cycle time is influenced by the PLL jitter.
For a single CLKOUT cycle (2 TCL) the deviation caused by the PLL jitter is below 1 ns (for
For longer periods the relative deviation decreases (see PLL deviation formula).

Variable Memory Cycles
The bus timing shown below is programmable via the BUSCONx registers. The duration
of ALE and two types of waitstates can be selected. This table summarizes the possible
bus cycle durations.
