Examples of Waveform Output Operation:

Figure 11.8 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.
