Legend: Setting available (valid). — Setting does not affect this mode.
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. The counter cannot be cleared by input capture A when reset-synchronized PWM mode is selected.
5. In complementary PWM mode, select the same clock source for channels 3 and 4.
6. Use the input capture A function in channel 1.
