Oscillator Configurations
9.2.1
OSCILLATOR TYPES
The PIC12CE67X can be operated in seven different
oscillator modes. The user can program three
configuration bits (FOSC2:FOSC0) to select one of
these seven modes:
LP:
Low Power Crystal
HS:
High Speed Crystal Resonator
XT:
Crystal/Resonator
INTRC*:
Internal 4 MHz Oscillator
EXTRC*: External Resistor/Capacitor
*Can be configured to support CLKOUT
9.2.2
CRYSTAL OSCILLATOR / CERAMIC
RESONATORS
In XT, HS or LP modes, a crystal or ceramic resonator
is connected to the GP5/OSC1/CLKIN and GP4/OSC2
pins
to
establish
oscillation
PIC12CE67X 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 9-3).

Note 1: See Capacitor Selection tables for
recommended values of C1 and C2.
2: A series resistor (RS) may be required for
AT strip cut crystals.
3: RF varies with the crystal chosen
(approx. value = 10 M
).

should consult the resonator manufacturer for
appropriate values of external components.

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 specification.
Since each crystal has its own characteristics, the
user should consult the crystal manufacturer for
appropriate values of external components.
