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 10.77 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).
