1.1.2
All of the devices in the PIC18(L)F2X/4XK22 family
offer ten different oscillator options, allowing users a
wide range of choices in developing application
hardware. These include:
• Four Crystal modes, using crystals or ceramic
• Two External Clock modes, offering the option of
• Two External RC Oscillator modes with the same

• A Phase Lock Loop (PLL) frequency multiplier,
Besides its availability as a clock source, the internal
oscillator block provides a stable reference source that
gives the family additional features for robust
operation:
• Fail-Safe Clock Monitor: This option constantly
• Two-Speed Start-up: This option allows the
resonators

for use as additional general purpose I/O.
