2. Examples of waveform output operation
Figure 10.6 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 such that 1 is output by compare match A, and 0 is output by compare match B. When
the set level and the pin level coincide, the pin level does not change.
Figure 10.7 shows an example of toggle output.
In this example, TCNT has been designated as a periodic counter (with counter clearing on
compare match B), and settings have been made such that the output is toggled by both
compare match A and compare match B.
