 Examples of Output Waveform Control at Synchronous Counter Clearing in
Clearing in Complementary PWM Mode
An example of the procedure for setting output waveform control at synchronous counter
clearing in complementary PWM mode is shown in figure 10.57.
Complementary PWM Mode
Figures 10.58 to 10.61 show examples of output waveform control in which the MTU2
operates in complementary PWM mode and synchronous counter clearing is generated
while the WRE bit in TWCR is set to 1. In the examples shown in figures 10.58 to 10.61,
synchronous counter clearing occurs at timing (3), (6), (8), and (11) shown in figure 10.56,
respectively.
In the MTU2S, these examples are equivalent to the cases when the MTU2S operates in
complementary PWM mode and synchronous counter clearing is generated while the SCC
bit is cleared to 0 and the WRE bit is set to 1 in TWCR.
