Timer/Counter0
Timer/Counter Prescaler

ATtiny28L/V
The ATtiny28 provides one general-purpose 8-bit Timer/Counter – Timer/Counter0.
Timer/Counter0 has prescaling selection from the 10-bit prescaling timer. The
Timer/Counter0 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.
Figure 28 shows the Timer/Counter prescaler.
Figure 28. Timer/Counter0 Prescaler
The four different prescaled selections are: the hardware modulator period, CK/64,
CK/256 and CK/1028, where CK is the oscillator clock. CK, external source and stop
can also be selected as clock sources.
Figure 29 shows the block diagram for Timer/Counter0.
