match signal
Compare match output timing
The compare match signal is generated in the last state in which TCNT and the general register
match (when TCNT changes from the matching value to the next value). When a compare
match signal is generated, the output value set in TIOR is output to the output compare pin
(TIOCA, TIOCB). Accordingly, when TCNT matches a general register, the compare match
signal is not generated until the next counter clock pulse. Figure 10.22 shows the output timing
of the compare match signal.
