CPU and EBC are clocked with the CPU clock signal

The specification of the external timing (AC Characteristics) depends on the period of the
CPU clock, called “TCP”.
The other peripherals are supplied with the system clock signal

factor F (
the output divider (F = PLLMUL+1 / (PLLIDIV+1 × PLLODIV+1)). The PLL circuit
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

circumstances.
The actual minimum value for TCP depends on the jitter of the PLL. As the PLL is
constantly adjusting its output frequency so it corresponds 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 e.g. for the operation of
timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train
