2.4.4
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. There are two modes: RC and RCIO.
2.4.4.1
In RC mode, the RC circuit connects to OSC1. OSC2/
CLKOUT outputs the RC oscillator frequency divided
by 4. This signal may be used to provide a clock for
external circuitry, synchronization, calibration, test or
other application requirements. Figure 2-5 shows the
external RC mode connections.
FIGURE 2-5:
2.4.4.2
In RCIO mode, the RC circuit is connected to OSC1.
OSC2 becomes an additional general purpose I/O pin.
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:
• input 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.

The Oscillator module has two independent, internal
oscillators that can be configured or selected as the
system clock source.
1.
2.
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<1:0>) bits of the OSCCON register. See
Section 2.9 “Clock Switching” for more information.
2.5.1
The INTOSC and INTOSCIO modes configure the
internal oscillators as the primary clock source. The
FOSC<3:0> bits in the CONFIG1H Configuration
register determine which mode is selected. See
Section 23.0 “Special Features of the CPU” for more
information.
In INTOSC mode, OSC1/CLKIN is available for general
purpose I/O. OSC2/CLKOUT outputs the selected
internal oscillator frequency divided by 4. The CLKOUT
signal may be used to provide a clock for external
circuitry, synchronization, calibration, test or other
application requirements.
In INTOSCIO mode, OSC1/CLKIN and OSC2/CLKOUT
are available for general purpose I/O.
2.5.2
The output of the HFINTOSC connects to a postscaler
and multiplexer (see Figure 2-1). One of eight
frequencies can be selected via software using the
IRCF<2:0> bits of the OSCCON register. See
Section 2.5.4 “Frequency Select Bits (IRCF)” for
more information.
The HFINTOSC is enabled when:
• SCS1 = 1 and IRCF<2:0> 000
• SCS1 = 1 and IRCF<2:0> = 000 and INTSRC = 1
• IESO bit of CONFIG1H = 1 enabling Two-Speed
• FCMEM bit of CONFIG1H = 1 enabling Two-
• FOSC<3:0> of CONFIG1H selects the internal
The HF Internal Oscillator (IOFS) bit of the OSCCON
register indicates whether the HFINTOSC is stable or not.
