4.7.2
The internal operation of the XC223xN is controlled by the internal system clock
Because the system clock signal
external sources using different mechanisms, the duration of the system clock periods
(TCSs) and their variation (as well as the derived external timing) depend on the
mechanism used to generate
for the XC223xN.

Note: The example of PLL operation shown in
The specification of the external timing (AC Characteristics) depends on the period of the
system clock (TCS).
