4.4.1
The internal operation of the XC161 is controlled by the internal master clock
The master clock signal
different mechanisms. The duration of master clock periods (TCMs) and their variation
(and also the derived external timing) depend on the used mechanism to generate
This influence must be regarded when calculating the timings for the XC161.

Note: The example for PLL operation shown in
The used mechanism to generate the master clock is selected by register PLLCON.
