TCNT Count Timing: Figure 9.34 shows TCNT count timing in internal clock operation, and
figure 9.35 shows TCNT count timing in external clock operation.
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.
