Hi,
I am attempting to use a 2323 with a 32.768KHz watch crystal without success.
I do not want to resort to an external oscillator. Some information on the 2323's oscillator
circuit would help. Surely someone has acheived this?
Thanks.

Hello Peter et al.,

The crystal oscillator on all current AVRs can only drive crystal with frequencies above 455kHz. Any frequency required below this level must be provided by an external clock. On some devices there's a special oscillator adapted to 32kHz, but this one is applicable to the timers only. The AT90S2323 doesn't have this special timer, I'm afraid.

Best regards,

Morten, AVR tech. support, Atmel FAE
