OCRnA changes its value from MAX, like in Figure 12-7 on page 89. When the OCRnA value
is MAX the OCn pin value is the same as the result of a down-counting Compare Match. To
ensure symmetry around BOTTOM the OCn value at MAX must correspond to the result of
an up-counting Compare Match.
The timer starts counting from a value higher than the one in OCRnA, and for that reason
misses the Compare Match and hence the OCn change that would have happened on the
way up.

Timer/Counter Timing Diagrams
The Timer/Counter is a synchronous design and the timer clock (clk
Tn) is therefore shown as a
clock enable signal in the following figures. The figures include information on when Interrupt
Flags are set. Figure 12-8 on page 90 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 cor-
rect PWM mode.
Figure 12-8. Timer/Counter Timing Diagram, no Prescaling
Figure 12-9 on page 90 shows the same timing data, but with the prescaler enabled.
Figure 12-9. Timer/Counter Timing Diagram, with Prescaler (f
clk_I/O/8)
Figure 12-10 on page 91 shows the setting of OCFnB in all modes and OCFnA in all modes
except CTC mode and PWM mode, where OCRnA is TOP.
