PIC24FJ256GB110 FAMILY
7.1
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 USB PLL block, which
generates both the USB module clock and a separate
system clock from the 96 MHZ PLL. Refer to
Section 7.5 “Oscillator Modes and USB Operation”
for additional information.
The internal FRC provides an 8 MHz clock source. It
can optionally be reduced by the programmable clock
divider to provide a range of system clock frequencies.
The selected clock source generates the processor
and peripheral clock sources. The processor clock
source is divided by two to produce the internal instruc-
tion cycle clock, F
cycle clock is also denoted by F
instruction cycle clock, F
OSCO I/O pin for some operating modes of the primary
oscillator.

Oscillator Mode
OSCO pin function is determined by the OSCIOFCN Configuration bit.
This is the default oscillator mode for an unprogrammed (erased) device.

The oscillator source (and operating mode) that is
used at a device Power-on Reset event is selected
using Configuration bit settings. The oscillator Config-

details). The Primary Oscillator Configuration bits,
POSCMD1:POSCMD0 (Configuration Word 2<1:0>),
and the Initial Oscillator Select Configuration bits,
FNOSC2:FNOSC0
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 Table 7-1.
7.2.1
The
Word 2<7:6>) are used to jointly configure device clock
switching and the Fail-Safe Clock Monitor (FSCM).
Clock switching is enabled only when FCKSM1 is
programmed (‘0’). The FSCM is enabled only when
FCKSM1:FCKSM0 are both programmed (‘00’).
