Section 13 Timer Z
13.4.2 Waveform Output by Compare Match
Timer Z can perform 0, 1, or toggle output from the corresponding FTIOA, FTIOB, FTIOC, or
FTIOD output pin using compare match A, B, C, or D.
Figure 13.12 shows an example of the setting procedure for waveform output by compare match.
Output selection
Select waveform output mode
Set output timing
[1] Select 0 output, 1 output, or toggle
output as a compare much output, by
means of TIOR. The initial values set in
TOCR are output unit the first compare
match occurs.
[2] Set the timing for compare match
generation in GRA/GRB/GRC/GRD.
[3] Enable or disable the timer output by
TOER.

Figure 13.12 Example of Setting Procedure for Waveform Output by Compare Match
1. Examples of waveform output operation
Figure 13.13 shows an example of 0 output/1 output.
In this example, TCNT has been designated as a free-running counter, and settings have been
made such that 0 is output by compare match A, and 1 is output by compare match B. When
the set level and the pin level coincide, the pin level does not change.
