9.2
9.2.1
The PIC12C67X can be operated in seven different
oscillator modes. The user can program three
configuration bits (F
seven modes:
• LP:
• HS:
• XT:
• INTRC*:
• EXTRC*: External Resistor/Capacitor
*Can be configured to support CLKOUT
9.2.2
In XT, HS or LP modes, a crystal or ceramic resonator
is connected to the GP5/OSC1/CLKIN and GP4/OSC2
pins
PIC12C67X 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, HS or LP modes, the
device can have an external clock source drive the
GP5/OSC1/CLKIN pin (Figure 9-2).

These values are for design guidance only. Since
each resonator has its own characteristics, the user
should consult the resonator manufacturer for
appropriate values of external components.
Note 1: For V
These values are for design guidance only. Rs may
be required in HS mode, as well as XT mode, to
avoid overdriving crystals with low drive level specifi-
cation. Since each crystal has its own characteris-
tics, the user should consult the crystal manufacturer
for appropriate values of external components.
