 Examples of Output Waveform Control at Synchronous Counter Clearing in Complementary PWM Mode

Figure 19.65 to Figure 19.68 show examples of output waveform control in which MTU3 and MTU4 operate in

complementary PWM mode and synchronous counter clearing is generated while the WRE bit in TWCRA is set to 1. In

the examples shown in Figure 19.65 to Figure 19.68 , synchronous counter clearing occurs at timing (3), (6), (8), and

(11) shown in Figure 19.63 , respectively.
