The following figures show the Timer/Counter in Synchronous mode, and the timer clock
(clk
be replaced by the Timer/Counter Oscillator clock. The figures include information on
when Interrupt Flags are set. Figure 60 contains timing data for basic Timer/Counter
operation. The figure shows the count sequence close to the MAX value in all modes
other than phase correct PWM mode.

Figure 61 shows the same timing data, but with the prescaler enabled.

The Timer starts counting from a value higher than the one in OCR2A, and for that
reason misses the Compare Match and hence the OCn that would have happened
on the way up.
