2. Examples of waveform output operation
Figure 11.6 shows an example of 0 output/1 output.
In this example, TCNT has been designated as a free-running counter, and settings have been
made so that 1 is output by compare match A, and 0 is output by compare match B. When the
set level and the pin level match, the pin level does not change.

In this example TCNT has been designated as a periodic counter (with counter clearing

compare match A and compare match B.
