9.2
9.2.1
The PIC16F630/676 can be operated in eight different
Oscillator Option modes. The user can program three
Configuration bits (FOSC2 through FOSC0) to select
one of these eight modes:
• LP
• XT
• HS
• RC
• INTOSC Internal Oscillator (2 modes)
• EC
9.2.2
In XT, LP or HS modes a crystal or ceramic resonator
is connected to the OSC1 and OSC2 pins to establish
oscillation (see Figure 9-1). The PIC16F630/676 oscil-
lator design requires the use of a parallel cut crystal.
Use of a series cut crystal may yield a frequency
outside of the crystal manufacturers specifications.
When in XT, LP or HS modes, the device can have an
external clock source to drive the OSC1 pin (see
Figure 9-2).
