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 9.9 shows an example of the setting procedure for waveform output by compare match

Select waveform output mode

[3]

[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.
