TCNT Count Timing
Figure 10.34 shows TCNT count timing in internal clock operation, and figure 10.35 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
