Waveform Output by Compare Match

The TPU can perform 0, 1, or toggle output from the corresponding output pin (TPU_TO pin)

using TGRA compare match.

(a)

Example of setting procedure for waveform output by compare match

Figure 15.5 shows an example of the setting procedure for waveform output by compare match.

Select waveform output mode

Output selection

Set output timing

Start count

[1]

[2]

Set external pin function

[3]

[4]

[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 TPU_TO pin until the

first compare match occurs.

[2] Set the timing for compare match generation in

TGRA.

[3] Set the external pin function in pin function

controller (PFC).

[4] Set the CST bit in TSTR to 1 to start the count

operation.
