ATtiny26(L)

1477B–AVR–04/02

Timer/Counters 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.

Prescaler

Figure 31 below shows the Timer/Counter prescaler.

Figure 31. Timer/Counter0 Prescaler

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.
