5.4.2
Internal 16 MHz RC oscillator
●
Default clock after reset 2 MHz (16 MHz/8)
●
Fast wakeup time
User trimming
The register CLK_HSITRIMR with two trimming bits plus one additional bit for the sign
permits frequency tuning by the application program. The adjustment range covers all
possible frequency variations versus supply voltage and temperature. This trimming does
not change the initial production setting.
5.4.3
Internal 128 kHz RC oscillator
The frequency of this clock is 128 kHz and it is independent from the main clock. It drives
the independent watchdog or the AWU wakeup timer.
In systems which do not need independent clock sources for the watchdog counters, the
128 kHz signal can be used as the system clock. This configuration has to be enabled by
setting an option byte (OPT3/OPT3N, bit LSI_EN).
5.4.4
Internal high-speed crystal oscillator
The internal high-speed crystal oscillator can be selected to deliver the main clock in normal
run mode. It operates with quartz crystals and ceramic resonators.
●
Frequency range: 1 MHz to 24 MHz
●
Crystal oscillation mode: preferred fundamental
●
I/Os: standard I/O pins multiplexed with OSCIN, OSCOUT
5.4.5
External clock input
An external clock signal can be applied to the OSCIN input pin of the crystal oscillator. The
frequency range is 0 to 24 MHz.
5.4.6
Clock security system (CSS)
The clock security system protects against a system stall in case of an external crystal clock
failure.
In case of a clock failure an interrupt is generated and the high-speed internal clock (HSI) is
automatically selected with a frequency of 2 MHz (16 MHz/8).
