2.0
2.1
Devices in the PIC18F97J60 family incorporate an
oscillator and microcontroller clock system that differs
from standard PIC18FXXJXX devices. The addition of
the Ethernet module, with its requirement for a stable
25 MHz clock source, makes it necessary to provide a
primary oscillator that can provide this frequency as
well as a range of different microcontroller clock
speeds. An overview of the oscillator structure is shown
in Figure 2-1.
Other oscillator features used in PIC18FXXJXX
enhanced microcontrollers, such as the internal RC
oscillator and clock switching, remain the same. They
are discussed later in this chapter.

2.2
The PIC18F97J60 family of devices can be operated in
five different oscillator modes:
1.
2.
3.
4.
5.
2.2.1
The oscillator mode is selected by programming the
FOSC2:FOSC0 Configuration bits. FOSC1:FOSC0
bits select the default primary oscillator modes, while
FOSC2 selects when INTRC may be invoked.
The OSCCON register (Register 2-2) selects the Active
Clock mode. It is primarily used in controlling clock
switching in power-managed modes. Its use is discussed
in Section 2.7.1 “Oscillator Control Register”.
The OSCTUNE register (Register 2-1) is used to select
the system clock frequency from the primary oscillator
source by selecting combinations of prescaler/postscaler
settings and enabling the PLL. Its use is described in
Section 2.6.1 “PLL Block”.
