Timer/Counter0 gets the prescaled clock 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, which triggers the counting.
Figure 18 shows the general Timer/Counter0 prescaler.

The four different prescaled selections are: CK/8, CK/64, CK/256, and CK/1024 where
CK is the Oscillator Clock. For the Timer/Counter0, added selections as CK, external
clock source and stop, can be selected as clock sources. Figure 19 shows the block dia-
gram for Timer/Counter0.
