Examples of waveform output operation: Figure 9.10 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 coincide, the pin level does not change.

Figure 9.11 shows an example of toggle output.

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

by compare match B), and settings have been made so that output is toggled by both compare

match A and compare match B.
