Timer/Counter0
Prescaler
The ATtiny26(L) provides two general purpose 8-bit Timer/Counters. The Timer/Counters have separate prescaling selection from the separate prescaler. The Timer/Counter0 clock (CK) as the clock timebase. The Timer/Counter1 has two clocking modes, a synchronous mode and an asynchronous mode. The synchronous mode uses the system clock (CK) as the clock timebase and asynchronous mode uses the fast peripheral clock (PCK) as the clock time base.
Figure 36 below shows the Timer/Counter prescaler.

TIMER/COUNTER0 CLOCK SOURCE
The four prescaled selections are: CK/8, CK/64, CK/256, and CK/1024 where CK is the oscillator clock. CK, external source, and stop, can also be selected as clock sources.
