Waveform Output by Compare Match: The TPU can perform 0, 1, or toggle output from the
corresponding output pin using compare match.
• Example of setting procedure for waveform output by compare match
Figure 11-9 shows an example of the setting procedure for waveform output by compare match
Output selection
Select waveform output mode [1]
Set output timing
[2]
[1] Select initial value 0 output or 1 output, and
compare match output value 0 output, 1 output,
or toggle output, by means of TIOR. The set
initial value is output at 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.
