I have a simple system with 32.768Khz crystal connected to XTAL1 and XTAL2
Do I need a special operation to enable it?
I did the following initializations in order to get a 1sec interrupt:
TCCR2B = 0x05; /* Osc/128 prescaler */
ASSR = _BV(AS2);
TIMSK2 = _BV(TOIE2); /* enable overflow interrupt */
However no interrupt was generated.
What did I do wrong?
