10.4.13 TCNT Capture at Crest and/or Trough in Complementary PWM Operation
The TCNT value is captured in TGR at either the crest or trough or at both the crest and trough
during complementary PWM operation. The timing for capturing in TGR can be selected by
TIOR.
Figure 10.93 shows an example in which TCNT is used as a free-running counter without being
cleared, and the TCNT value is captured in TGR at the specified timing (either crest or trough, or
both crest and trough).
