Waveform Output by Compare Match
The TPU can perform low, high, or toggle output from the corresponding output pin using a compare match.

Example of setting procedure for waveform output by compare match
Figure 15.6 shows an example of the setting procedure for waveform output by a compare match.

<Waveform output>
Select an initial value from low-output
or high-output and compare match
output value from low-output, high-
output, or toggle-output by TIOR. The
set initial value is output on the
TIOCyn pin until the first compare
match occurs (y = A to D, n = 0 to 11).

Set the timing for generating a
compare match in TGRy.

Set the CSTj bit in TSTRy to start
count operation (y = A, B, j = 0 to 5).

Examples of waveform output operation
Figure 15.7 shows an example of low output/high output.
In this example, TPUm.TCNT has been set as a free-running counter, and settings have been made so that high is output
by compare match A and low is output by compare match B. When the set level and the pin level match, the pin level
does not change.
