PIC18F97J60 FAMILY
TABLE 2-2:
2.7
The PIC18F97J60 family of devices includes a feature
that allows the device clock source to be switched from
the main oscillator to an alternate clock source. These
devices also 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 and the External Clock modes.
The particular mode is defined by the FOSC2: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. The PIC18F97J60
family of devices offers the Timer1 oscillator as a second-
ary oscillator. In all power-managed modes, this oscillator
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 the RC0/T1OSO/T13CKI and RC1/T1OSI
pins. Loading capacitors are also connected from each
pin to ground. The Timer1 oscillator is discussed in
greater detail in Section 12.3 “Timer1 Oscillator”.
In addition to being a primary clock source, the internal
oscillator 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 PIC18F97J60 family devices
are shown in Figure 2-1. See Section 24.0 “Special
Features of the CPU” for Configuration register details.
