2.1
The PIC18F6585/8585/6680/8680 devices can be
operated in eleven different oscillator modes. The user
can program four configuration bits (FOSC3, FOSC2,
FOSC1 and FOSC0) to select one of these eleven
modes:

10. ECIO+PLL
11. HS+SPLL
2.2
In XT, LP, HS, HS+PLL or HS+SPLL 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 PIC18F6585/8585/6680/8680 oscillator design
requires the use of a parallel cut crystal.
