Complementary PWM Mode

In the complementary PWM mode, three-phase output of non-overlapping positive and negative PWM waveforms can
be obtained by combining channels 3 and 4. PWM waveforms without non-overlapping interval are also available.
In complementary PWM mode, TIOC3B, TIOC3D, TIOC4A, TIOC4B, TIOC4C, and TIOC4D pins function as PWM
output pins, the TIOC3A pin can be set for toggle output synchronized with the PWM period. TCNT_3 and TCNT_4
function as up/down counters.
Table 10.52 shows the PWM output pins used. Table 10.53 shows the settings of the registers used.

Note: Avoid setting the TIOC3C pin as a timer I/O pin in the complementary PWM mode.
