11.2
11.2.1
The PIC16F870/871 can be operated in four different
Oscillator modes. The user can program two configura-
tion bits (FOSC1 and FOSC0) to select one of these
four modes:
• LP
• XT
• HS
• RC
11.2.2
In XT, LP or HS modes, a crystal or ceramic resonator
is connected to the OSC1/CLKI and OSC2/CLKO pins
to establish oscillation (Figure 11-1). The PIC16F870/
871 oscillator design requires the use of a parallel cut
crystal. Use of a series cut crystal may give a frequency
out of the crystal manufacturers specifications. When in
XT, LP or HS modes, the device can have an external
clock source to drive the OSC1/CLKI pin (Figure 11-2).
