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.
The FRC frequency depends on the FRC accuracy
(see
Tuning register (see
8.1.1.2
The primary oscillator can use one of the following as
its clock source:
• MS (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).

The clock signals generated by the FRC and primary
oscillators can be optionally applied to an on-chip 4x
Phase-Locked Loop (PLL) to provide faster output
