18.4.8
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.
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 increment/decrement counters.
Table 18.39 shows the PWM output pins used. Table 18.40 shows the settings of the registers
used.
A function to directly cut off the PWM output by using an external signal is supported as a port
function.
