Output Compare Output Timing: The compare-match signal is generated at the final state of
TCNT and TGR matching. When a compare-match signal is issued, the output value set in TIOR
is output to the output compare output pin (the TIOC pin). After TCNT and TGR matching, a
compare-match signal is not issued until immediately before the TCNT input clock.
Output compare output timing (normal mode and PWM mode) is shown in figure 10.37.
