Output Compare Output Timing: A compare match signal is generated in the final state in
which TCNT and TGR match (the point at which the count value matched by TCNT is updated).
When a compare match signal is generated, the output value set in TIOR is output at the output
compare output pin. After a match between TCNT and TGR, the compare match signal is not
generated until the TCNT input clock is generated.
Figure 11-36 shows output compare output timing.
