Complementary PWM Mode

In the complementary PWM mode, three-phase output of non-overlapping positive and negative

PWM waveforms can be obtained using channels 3 and 4.

In complementary PWM mode, TIOC3B, TIOC3D, TIOC4A, TIOC4B, TIOC4C, and TIOC4D

pins become PWM output pins, the TIOC3A pin can be set for toggle output synchronized with

the PWM period. TCNT3 and TCNT4 function as increment/decrement counters.

Table 12.15 shows the PWM output pins used. Table 12.16 shows the settings of the registers.

A function to directly cut off the PWM output by using an external signal is supported as a port

function.
