3.0
3.1
PIC18F1230/1330 devices can be operated in ten
different oscillator modes. The user can program the
Configuration bits, FOSC3:FOSC0, in Configuration
Register 1H to select one of these ten modes:

2.
3.
4.
5.
6.

10. ECIO
3.2
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 3-1 shows
the pin connections.
The oscillator design requires the use of a parallel
resonant crystal.
