(b) Examples of waveform output operation

Figure 10.10 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 10.10 Example of 0 Output/1 Output Operation

Figure 10.11 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.
