PIC18F2X1X/4X1X
2.7
Like previous PIC18 devices, the PIC18F2X1X/4X1X
family includes a feature that allows the device clock
source to be switched from the main oscillator to an
alternate low-frequency clock source. PIC18F2X1X/
4X1X devices offer two alternate clock sources. When
an alternate clock source is enabled, the various
power-managed operating modes are available.
Essentially, there are three clock sources for these
devices:
• Primary oscillators
• Secondary oscillators
• Internal oscillator block
The primary oscillators include the External Crystal
and Resonator modes, the External RC modes, the
External Clock modes and the internal oscillator block.
The particular mode is defined by the FOSC3:FOSC0
Configuration bits. The details of these modes are
covered earlier in this chapter.

The secondary oscillators are those external sources
not connected to the OSC1 or OSC2 pins. These
sources may continue to operate even after the
controller is placed in a power-managed mode.
PIC18F2X1X/4X1X devices offer the Timer1 oscillator
as a secondary oscillator. This oscillator, in all power-
managed modes, is often the time base for functions
such as a real-time clock.
Most often, a 32.768 kHz watch crystal is connected
between the RC0/T1OSO/T13CKI and RC1/T1OSI
pins. Like the LP mode oscillator circuit, loading
capacitors are also connected from each pin to ground.
The Timer1 oscillator is discussed in greater detail in
Section 11.3 “Timer1 Oscillator”.
In addition to being a primary clock source, the internal
oscillator block is available as a power-managed
mode clock source. The INTRC source is also used as
the clock source for several special features, such as
the WDT and Fail-Safe Clock Monitor.
The clock sources for the PIC18F2X1X/4X1X devices
are shown in Figure 2-8. See Section 22.0 “Special
Features of the CPU” for Configuration register details.
