dsPIC33FJ12MC201/202
8.1
The dsPIC33FJ12MC201/202 devices provide seven
system clock options:
• Fast RC (FRC) Oscillator
• FRC Oscillator with PLL
• Primary (XT, HS or EC) Oscillator
• Primary Oscillator with PLL
• Secondary (LP) Oscillator
• Low-Power RC (LPRC) Oscillator
• FRC Oscillator with postscaler
8.1.1
8.1.1.1
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.
8.1.1.2
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
8.1.1.3
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.
8.1.1.4
The Low-Power RC (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).

8.1.1.5
The clock signals generated by the FRC and primary
oscillators can be optionally applied to an on-chip
Phase-Locked Loop (PLL) to provide a wide range of
output
configuration is described in Section 8.1.3 “PLL
Configuration”.
The FRC frequency depends on the FRC accuracy
(see Table 24-18) and the value of the FRC Oscillator
Tuning register (see Register 8-4).
8.1.2
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 21.1 “Configuration
Bits” for further details.) The Initial Oscillator

(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 8-1.
