9.1
The
dsPIC33FJ64GS406/606/608/610 devices provide six
system clock options:
• Fast RC (FRC) Oscillator
• FRC Oscillator with PLL
• Primary (XT, HS, or EC) Oscillator
• Primary Oscillator with PLL
• Low-Power RC (LPRC) Oscillator
• FRC Oscillator with Postscaler
• Secondary (LP) Oscillator
9.1.1
The Fast RC (FRC) internal oscillator runs at a nominal
frequency of 7.37 MHz. User software can tune the
FRC frequency. User software can optionally specify a
factor (ranging from 1:2 to 1:256) by which the FRC
clock frequency is divided. This factor is selected using
the FRCDIV<2:0> (CLKDIV<10:8>) bits.
The primary oscillator can use one of the following as
its clock source:
• XT (Crystal): Crystals and ceramic resonators in
• HS (High-Speed Crystal): Crystals in the range of
• EC (External Clock): The external clock signal is
The secondary (LP) oscillator is designed for low power
and uses a 32.768 kHz crystal or ceramic resonator.
The LP oscillator uses the SOSCI and SOSCO pins.
The LPRC internal oscIllator runs at a nominal
frequency of 32.768 kHz. It is also used as a reference
clock by the Watchdog Timer (WDT) and Fail-Safe
Clock Monitor (FSCM).

configuration is described in Section 9.1.3 “PLL
Configuration”.
The FRC frequency depends on the FRC accuracy
(see Table 27-20) and the value of the FRC Oscillator
Tuning register (see Register 9-4).
9.1.2
The oscillator source 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 Section 24.1 “Configuration Bits” for further
details.) The Initial Oscillator Selection Configuration
bits, FNOSC<2:0> (FOSCSEL<2:0>), and the Primary
Oscillator
POSCMD<1:0> (FOSC<1:0>), select the oscillator
source that is used at a Power-on Reset. The FRC
primary oscillator is the default (unprogrammed)
selection.
The Configuration bits allow users to choose among
12 different clock modes, shown in Table 9-1.
