Examples of Complementary PWM Mode
Figure 10.35 shows an example of operation in complementary PWM mode. TCNT3 and TCNT4
operate as up/down-counters, counting down from compare match between TCNT3 and GRA3
and counting up from the point at which TCNT4 underflows. During each up-and-down counting
cycle, PWM waveforms are generated by compare match with general registers GRB3, GRA4,
and GRB4. Since TCNT3 is initially set to a higher value than TCNT4, compare match events
occur in the sequence TCNT3, TCNT4, TCNT4, TCNT3.
