5.2.1.4
Secondary Oscillator
The secondary oscillator is a separate crystal oscillator
that is associated with the Timer1 peripheral. It is opti-
mized for timekeeping operations with a 32.768 kHz
crystal connected between the SOSCO and SOSCI
device pins.
The secondary oscillator can be used as an alternate
system clock source and can be selected during
run-time using clock switching. Refer to Section 5.3
for more information.

5.2.1.5
External RC Mode
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. The
function of the OSC2/CLKOUT pin is determined by the
state of the CLKOUTEN bit in Configuration Word 1.
Figure 5-6 shows the external RC mode connections.
FIGURE 5-6:
EXTERNAL RC MODES
The RC oscillator frequency is a function of the supply
voltage, the resistor (REXT) and capacitor (CEXT) values
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.

Always verify oscillator performance over
the VDD and temperature range that is
expected for the application.
