2.1
The PIC18F2331/2431/4331/4431 devices can be
operated in 10 different oscillator modes. The user can
program the configuration bits F
uration register 1H to select one of these 10 modes:

2.2
In XT, LP, HS or HSPLL 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 oscillator design requires the use of a parallel cut
crystal.

Capacitor values are for design guidance only.
These capacitors were tested with the resonators
listed below for basic start-up and operation. These
values are not optimized.
Different capacitor values may be required to produce
acceptable oscillator operation. The user should test
the performance of the oscillator over the expected
