Notes: *1 In PWM mode, the input capture function cannot be used. When compare match A and
compare match B occur simultaneously, the compare match signal is inhibited.
*2 When set for complementary PWM mode, do not simultaneously set channel 3 and
channel 4 to function synchronously.
*3 Counter clearing works with reset-synchronized PWM mode, but TCNT4 runs
independently. The output waveform is not affected.
*4 Clock selection when complementary PWM mode is set should be the same for
channels 3 and 4.
*5 In reset-synchronized PWM mode, TCNT4 runs independently. The output waveform is
not affected.
