(b) Examples of waveform output operation
Figure 18.3 shows an example of 0 output/1 output.
In this example, TRGCNT 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 match, the pin level does not change.

Figure 18.4 shows an example of toggle output. In this example TRGCNT 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.
