If bits CKS2 to CKS0 in either TCR0 or TCR1 are set to B’100, the 8-bit timers of the two channels are cascaded. With
this configuration, a single 16-bit timer could be used (16-bit timer mode) or compare matches of the 8-bit channel 0 could
be counted by the timer of channel 1 (compare match counter mode). In this case, the timer operates as below.
16-Bit Counter Mode: When bits CKS2 to CKS0 in TCR0 are set to B'100, the timer functions as a single 16-bit timer
with channel 0 occupying the upper 8 bits and channel 1 occupying the lower 8 bits.
Compare Match Counter Mode: When bits CKS2 to CKS0 in TCR1 are B'100, TCNT1 counts compare match A’s for
channel 0.
Channels 0 and 1 are controlled independently. Conditions such as setting of the CMF flag, generation of interrupts,
output from the TMO pin, and counter clear are in accordance with the settings for each channel.
Note on Usage: If the 16-bit counter mode and compare match counter mode are set simultaneously, the input clock
pulses for TCNT0 and TCNT1 are not generated and thus the counters will stop operating. Software should therefore
avoid using both these modes.

Pin output
The CMF flag in TCSR0 is set to 1 when a 16-bit compare match event occurs.
The CMF flag in TCSR1 is set to 1 when a lower 8-bit compare match event occurs.
If the CCLR1 and CCLR0 bits in TCR0 have been set for counter clear at compare match, the 16-bit counter
The settings of the CCLR1 and CCLR0 bits in TCR1 are ignored. The lower 8 bits cannot be cleared
