15. Counter Clearing by TGRA_3 Compare Match
Notes: 1. Use this function only in complementary PWM mode 1 (transfer at crest)
In complementary PWM mode, by setting the CCE bit in the timer waveform control register
(TWCR), it is possible to have TCNT_3, TCNT_4, and TCNTS cleared by TGRA_3 compare
match.
Figure 9.62 illustrates an operation example.
