Section 11 Multi-Function Timer Pulse Unit 2 (MTU2)
11.4.8 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 11.52 shows the PWM output pins used. Table 11.53 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.
