ATtiny26(L)
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.
Figure 36. Timer/Counter0 Prescaler
The four prescaled selections are: CK/8, CK/64, CK/256, and CK/1024 where CK is the oscilla-
tor clock. CK, external source, and stop, can also be selected as clock sources.
