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 (TIOC pin).
After a match between TCNT and TGR, the compare match signal is not generated until the
TCNT input clock is generated.
Figure 9.33 shows output compare output timing.
