4.0
4.1
PIC16C5Xs can be operated in four different oscillator
modes. The user can program two configuration bits
(FOSC1:FOSC0) to select one of these four modes:

2.
3.
4.
4.2
In XT, LP or HS modes, a crystal or ceramic resonator
is connected to the OSC1/CLKIN and OSC2/CLKOUT
pins
PIC16C5X oscillator design requires the use of a paral-
lel cut crystal. Use of a series cut crystal may give a fre-
quency out of the crystal manufacturers specifications.
When in XT, LP or HS modes, the device can have an
external clock source drive the OSC1/CLKIN pin
(Figure 4-2).

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 specification.
Since each crystal has its own characteristics, the
user should consult the crystal manufacturer for
