Legend:
Notes: 1. Master enable bit settings are valid only during waveform output.
2. The input capture function cannot be used in PWM mode. If compare match A and compare match B occur simultaneously, the compare match signal is inhibited.
3. Do not set both channels 3 and 4 for synchronous operation when complementary PWM mode is selected.
4. When reset-synchronized PWM mode is selected, TCNT4 operates independently and the counter clearing function is available. Waveform output is not affected.
5. In complementary PWM mode, select the same clock source for channels 3 and 4.
6. TCR4 settings are valid in reset-synchronized PWM mode, but TCNT4 operates independently, without affecting waveform output.
