2.1
The PIC18FXX2 can be operated in eight different
Oscillator modes. The user can program three configu-
ration bits (FOSC2, FOSC1, and FOSC0) to select one
of these eight modes:

3.
4.
5.
6.
7.
8.
2.2
In XT, LP, HS or HS+PLL Oscillator modes, a crystal or
ceramic resonator is connected to the OSC1 and
OSC2 pins to establish oscillation. Figure 2-1 shows
the pin connections.
The PIC18FXX2 oscillator design requires the use of a
parallel cut crystal.
