Channel 0 (16-bit count mode): Count on 8TCNT1 overflow
signal*¹
Channel 1 (compare match count mode): Count on 8TCNT0
compare match A*¹
Channel 2 (16-bit count mode): Count on 8TCNT3 overflow
signal*²
Channel 3 (compare match count mode): Count on 8TCNT2
compare match A*²
1
External clock, counted on rising edge
1
0
External clock, counted on falling edge
1
External clock, counted on both rising and falling edges
Notes: 1. If the clock input of channel 0 is the 8TCNT1 overflow signal and that of channel 1 is
the 8TCNT0 compare match signal, no incrementing clock is generated. Do not use
this setting.
2. If the clock input of channel 2 is the 8TCNT3 overflow signal and that of channel 3 is
the 8TCNT2 compare match signal, no incrementing clock is generated. Do not use
this setting.
