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 (TIOC) pin. After a
match between TCNT and TGR, the compare match signal is not generated until the TCNT input
clock is generated. Figure 12.35 shows output compare output timing.
Input Capture Signal Timing:
Figure 12.36 shows input capture signal timing.
