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.

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.
