Like
PIC18F6310/6410/8310/8410 family includes a feature
that allows the device clock source to be switched from
the main oscillator to an alternate low-frequency clock
source. PIC18F6310/6410/8310/8410 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 FOSC<3:0>
Configuration bits. The details of these modes are
covered earlier in this chapter.

register details.
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.
PIC18F6310/6410/8310/8410 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 (RTC).
Most often, a 32.768 kHz watch crystal is connected
between
RC1/T1OSI/CCP2 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 13.3 “Timer1
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.
