Examples of Waveform Output Operation:

Figure 12.8 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.
