Clock source modes can be classified as external or
internal.
• Internal clock source (INTOSC) is contained
• The External Clock mode (EC) relies on an
The system clock can be selected between external or
internal clock sources via the FOSC bit of the
Configuration Word.
4.3
The internal clock sources are contained within the
oscillator module. The internal oscillator block has two
internal oscillators that are used to generate all internal
system clock sources: the 16 MHz High-Frequency
Internal Oscillator (HFINTOSC) and the 31 kHz
(LFINTOSC).
The HFINTOSC consists of a primary and secondary
clock. The secondary clock starts first with rapid start-
up time, but low accuracy. The secondary clock ready
signal is indicated with the HFIOFR bit of the OSCCON
register. The primary clock follows with slower start-up
time and higher accuracy. The primary clock is stable
when the HFIOFS bit of the OSCCON register bit goes
high.
4.3.1
When the FOSC bit of the Configuration Word is
cleared, the INTOSC mode is selected. When INTOSC
is selected, CLKIN pin is available for general purpose
I/O. See

The output of the 16 MHz HFINTOSC is connected to

OSCCON register select the frequency output of the
internal oscillator:
• HFINTOSC
• LFINTOSC
There is no delay when switching between HFINTOSC
frequencies with the IRCF bits. This is because the
switch involves only a change to the frequency output
divider.
