Trimming
A trimming register permits frequency readjustment to a precision of 1.5 % by the
application program. The initial final-test setting remains unchanged.
Internal 128 kHz RC oscillator
Frequency: 128 kHz, independent from the main clock
Precision: 12.5 % over full voltage and frequency range, minimum frequency 100 kHz
This clock drives the watchdog or the wake-up timer also automatically activates the internal
128 kHz oscillator.
Internal high-speed crystal oscillator
The internal high-speed crystal oscillator delivers the main clock in normal run mode. It
operates with quartz and ceramic resonators.
