12.4.12 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 12.82 is an operating 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).
