The internal operation of the XC167 is controlled by the internal master clock
f
MC
.
The master clock signal
f
MC
can be generated from the oscillator clock signal
f
OSC
via
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
f
MC
.
This influence must be regarded when calculating the timings for the XC167.
Definition of Internal Timing
Figure 15
Generation Mechanisms for the Master Clock
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.
The used mechanism to generate the master clock is selected by register PLLCON.
