The oscillator module has a wide variety of clock sources
and selection features that allow it to be used in a wide
range of applications while maximizing performance and
minimizing power consumption. Figure 7-1 illustrates a
block diagram of the oscillator module.
Clock sources can be configured from external
oscillators, quartz crystal resonators, ceramic resonators
and Resistor-Capacitor (RC) circuits. In addition, the
system can be configured to use an internal calibrated
high-frequency oscillator as clock source, with a choice
of selectable speeds via software.
