4.3.2
When PLL operation is configured (PLL_CLC.LOCK = 1), the on-chip phase locked loop
is enabled and provides the master clock. The PLL multiplies the input frequency by the
factor F (
Factor), and the output divider (F = NDIV+1 / (PDIV+1
synchronizes the master clock to the input clock. This synchronization is done smoothly,
i.e. the master clock frequency does not change abruptly.
Due to this adaptation to the input clock, the frequency of
it is locked to

The timing listed in the AC Characteristics refers to TCPs. Because

circumstances.
The actual minimum value for TCP depends on the jitter of the PLL. As the PLL is
constantly adjusting its output frequency in order to correspond to the applied input
frequency (crystal or oscillator), the relative deviation for periods of more than one TCP
is lower than for one single TCP (see formula and
This is especially important for bus cycles using waitstates and for the operation of
timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train
generation or measurement, lower baud rates, etc.) the deviation caused by the PLL
jitter is negligible.
The value of the accumulated PLL jitter depends on the number of consecutive VCO
output cycles within the respective timeframe. The VCO output clock is divided by the
output prescaler (K = KDIV+1) to generate the master clock signal
number of VCO cycles can be represented as K ×
