4.4.1 Definition of Internal Timing

The internal operation of the XC236x is controlled by the internal system clock fSYS.

Because the system clock signal fSYS can be generated from several internal and

external sources via different mechanisms, the duration of system clock periods (TCSs)

and their variation (and also the derived external timing) depend on the used mechanism

to generate fSYS. This influence must be regarded when calculating the timings for the

XC236x.

Note: The example for PLL operation shown in Figure 15 refers to a PLL factor of 1:4,

the example for prescaler operation refers to a divider factor of 2:1.
