If the count input of channel 0 (channel 2) is the TCNT1 (TCNT3) overflow signal and
that of channel 1 (channel 3) is the TCNT1 (TCNT3) compare-match signal, no
incrementing clock will be generated. Do not use this setting.

Description
Clock Select 2 to 0
The input clock can be selected from three clocks divided
from the system clock ( ). When use of an external clock
is selected, three types of count can be selected: at the
rising edge, the falling edge, and both rising and falling
edges.
000: Clock input disabled
001: /8 internal clock source, counted on the falling
010: /64 internal clock source, counted on the falling
011: /8192 internal clock source, counted on the falling
100: For channel 0: Counted on TCNT1 overflow signal *
101: External clock source, counted at rising edge
110: External clock source, counted at falling edge
