TOP the output will be continuously high for non-inverted PWM mode. For inverted PWM the output will have the
opposite logic values.
At the very start of period 2 in Figure 11-7 on page 67 OCnx has a transition from high to low even though there is no
Compare Match. The point of this transition is to guaratee symmetry around BOTTOM. There are two cases that give a
transition without Compare Match.
OCR0x changes its value from TOP, like in Figure 11-7 on page 67. When the OCR0x value is TOP the OCnx pin
value is the same as the result of a down-counting Compare Match. To ensure symmetry around BOTTOM the
OCnx value at TOP must correspond to the result of an up-counting Compare Match.
The timer starts counting from a value higher than the one in OCR0x, and for that reason misses the Compare
Match and hence the OCnx change that would have happened on the way up.

Timer/Counter Timing Diagrams
The Timer/Counter is a synchronous design and the timer clock (clkT0) is therefore shown as a clock enable signal in the
following figures. The figures include information on when Interrupt Flags are set. Figure 11-8 on page 68 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 11-9 on page 68 shows the same timing data, but with the prescaler enabled.

clk_I/O/8)
Figure 11-10 on page 69 shows the setting of OCF0B in all modes and OCF0A in all modes except CTC mode and PWM
mode, where OCR0A is TOP.
