Figure 10.4 Periodic Counter Operation
Waveform Output by Compare Match: The TPU can perform 0, 1, or toggle output from the
corresponding output pin using compare match.
1. Example of setting procedure for waveform output by compare match
Figure 10.5 shows an example of the setting procedure for waveform output by compare
match.
Output selection
Select waveform output mode [1]
[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 unit 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.
