In complementary PWM mode, TCNT3 and TCNT4 overshoot and undershoot at the transitions
between up-counting and down-counting. The setting conditions for the IMFA bit in channel 3 and
the OVF bit in channel 4 differ from the usual conditions. In buffered operation the buffer transfer
conditions also differ. Timing diagrams are shown in figures 10.37 and 10.38.
