Waveform Output by Compare Match
The TPU can perform 0, 1, or toggle output from the corresponding output pin using a compare
match.
Note: * The H8SX/1527 does not have pins TIOCA4, TIOCB4, TIOCA5, and TIOCB5 for
channels 4 and 5. Therefore, 0-, 1-, or toggle-output waveform and PWM waveform at
an input capture input and a compare match cannot be output.

Figure 9.5 Periodic Counter Operation

[1] Select initial value from 0-output or 1-output,
and compare match output value from 0-output,
1-output, or toggle-output, by means of TIOR.
[1]
The set initial value is output on the TIOC pin
until the first compare match occurs.

[2] Set the timing for compare match generation in
TGR.

[3] Set the CST bit in TSTR to 1 to start the count
operation.
