8.4.4
The external Resistor-Capacitor (RC) modes support
the use of an external RC circuit. This allows the
designer maximum flexibility in frequency choice while
keeping costs to a minimum when clock accuracy is not
required.
The RC circuit connects to OSC1. OSC2/CLKOUT is
available for general purpose I/O or CLKOUT.
Figure 8-5 shows the external RC mode connections.
FIGURE 8-5:
The RC oscillator frequency is a function of the supply
voltage, the resistor (R
and the operating temperature. Other factors affecting
the oscillator frequency are:
• threshold voltage variation
• component tolerances
• packaging variations in capacitance
The user also needs to take into account variation due
to tolerance of external RC components used.

8.5
The oscillator module has three independent, internal
oscillators that can be configured or selected as the
system clock source.
1.
2.
3.
The system clock speed can be selected via software
using the Internal Oscillator Frequency Select bits
IRCF<2:0> of the OSCCON register.
The system clock can be selected between external or
internal clock sources via the System Clock Selection
(SCS) bits of the OSCCON register. See Section 8.6
“Clock Switching” for more information.
8.5.1
The INTOSC mode configures the internal oscillators
as the system clock source when the device is
programmed using the oscillator selection or the
FOSC<2:0> bits in the Configuration Word Register 1
(CONFIG1).
In INTOSC mode, OSC1/CLKIN is available for general
purpose I/O. OSC2/CLKOUT is available for general
purpose I/O or CLKOUT.
