8.2
8.2.1
The PIC12C5XX can be operated in four different
oscillator
configuration bits (FOSC1:FOSC0) to select one of
these four modes:
• LP:
• XT:
• INTRC: Internal 4 MHz Oscillator
• EXTRC: External Resistor/Capacitor
8.2.2
In XT or LP modes, a crystal or ceramic resonator is
connected to the GP5/OSC1/CLKIN and GP4/OSC2
pins
PIC12C5XX oscillator design requires the use of a
parallel cut crystal. Use of a series cut crystal may give
a
specifications. When in XT or LP modes, the device
can have an external clock source drive the GP5/
OSC1/CLKIN pin (Figure 8-3).
