PIC24FJ256GA110 FAMILY
8.1
The system clock source can be provided by one of
four sources:
• Primary Oscillator (POSC) on the OSCI and
• Secondary Oscillator (SOSC) on the SOSCI and
• Fast Internal RC (FRC) Oscillator
• Low-Power Internal RC (LPRC) Oscillator
The Primary Oscillator and FRC sources have the
option of using the internal 4x PLL. The frequency of
the FRC clock source can optionally be reduced by the
programmable clock divider. The selected clock source
generates the processor and peripheral clock sources.
The processor clock source is divided by two to pro-
duce the internal instruction cycle clock, F
document, the instruction cycle clock is also denoted
by F
can be provided on the OSCO I/O pin for some
operating modes of the Primary Oscillator.

The oscillator source (and operating mode) that is used
at a device Power-on Reset event is selected using
Configuration bit settings. The oscillator Configuration
bit settings are located in the Configuration registers in
the program memory (refer to

Select
(Configuration Word 2<10:8>), select the oscillator
source that is used at a Power-on Reset. The FRC
Primary Oscillator with Postscaler (FRCDIV) is the
default (unprogrammed) selection. The Secondary
Oscillator, or one of the internal oscillators, may be
chosen by programming these bit locations.
The Configuration bits allow users to choose between
the various clock modes, shown in

The

switching and the Fail-Safe Clock Monitor (FSCM).
Clock switching is enabled only when FCKSM1 is
programmed (‘0’). The FSCM is enabled only when
FCKSM<1:0> are both programmed (‘00’).
