ATmega103(L)
38
The ATmega103(L) provides three general purpose Timer/Counters – two 8-bit T/Cs
and one 16-bit T/C. Timer/Counter0 optionally can be asynchronously clocked from an
external Oscillator. This Oscillator is optimized for use with a 32.768 kHz crystal,
enabling use of Timer/Counter0 as a Real Time Clock (RTC). Timer/Counter0 has its
own prescaler. Timer/Counters 1 and 2 have individual prescaling selection from the
same 10-bit prescaling timer. These Timer/Counters can either be used as a Timer with
an internal clock time base or as a counter with an external pin connection that triggers
the counting.

TIMER/COUNTER2 CLOCK SOURCE
For Timer/Counters 1 and 2, the four different prescaled selections are: CK/8, CK/64,
CK/256 and CK/1024, where CK is the CPU clock. Observe that CPU clock frequency
can be lower than the XTAL frequency if the XTAL divider is enabled. For
Timer/Counters 1 and 2, added selections as CK, external source and stop can be
selected as clock sources.
