Counter Unit of ATmega644PA-AUR
ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P uses the same type of crystal oscillator for Lowfrequency Crystal Oscillator and Timer/Counter Oscillator. See ”Low Frequency Crystal Oscillator” on page 43 for details on the oscillator and crystal requirements. The device can operate its Timer/Counter2 from an external 32.768kHz watch crystal or a external clock source. See ”Clock source connections” on page 40 for details. Applying an external clock source to TOSC1 can be done if EXTCLK in the ASSR Register is written to logic one. See ”OCR2B – Output Compare Register B” on page 163 for further description on selecting external clock as input instead of a 32.768kHz watch crystal.
