(b) Examples of waveform output operation
Figure 16.6 shows an example of 0-output and 1-output.
In this example, TPUn_TCNT has been designated as a free-running counter, and settings have
been made so that 1 or 0 is output by compare match A. When the set level and the pin level
match, the pin level does not change.

Figure 16.7 shows an example of toggle output.
In this example, TPUn_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
compare match A.
