Timer/Counter
Oscillator
2490Q–AVR–06/10
For AVR microcontrollers with Timer/Counter Oscillator pins (TOSC1 and TOSC2), the crystal is
connected directly between the pins. No external capacitors are needed. The Oscillator is opti-
mized for use with a 32.768 kHz watch crystal. Applying an external clock source to TOSC1 is
not recommended.
Note:
The Timer/Counter Oscillator uses the same type of crystal oscillator as Low-Frequency Oscillator
and the internal capacitors have the same nominal value of 36 pF.
