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.

[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.

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.
