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 9.87 shows output compare output timing (normal mode and PWM mode) and figure 9.88
shows output compare output timing (complementary PWM mode and reset synchronous PWM
mode).
