External clock: Counting on both rising and falling edges
Note: * No countup clock is generated if the channel 0 (channel 2) clock input is the TCNT1
(TCNT3) overflow signal, and that the channel 1 (channel 3) clock input is the TCNT0
(TCNT2) compare match signal. Do not, therefore, attempt to make such a setting.
