4.1
The PIC16F917/916/914/913 has a wide variety of
clock sources and selection features to allow it to be
used in a wide range of applications while maximizing
performance and minimizing power consumption.
Figure 4-1
PIC16F917/916/914/913 clock sources.
Clock sources can be configured from external oscillators,
quartz crystal resonators, ceramic resonators, and
Resistor-Capacitor (RC) circuits. In addition, the system
clock source can be configured from one of two internal
oscillators, with a choice of speeds selectable via
software. Additional clock features include:
• Selectable system clock source between external
• Two-Speed Clock Start-up mode, which
• Fail-Safe Clock Monitor (FSCM) designed to
