Compare match
signal
FTIOA to FTIOD
The compare match signal is generated in the last state in which TCNT and GR match (when
TCNT changes from the matching value to the next value). When the compare match signal is
generated, the output value selected in TIOR is output at the compare match output pin
(FTIOA, FTIOB, FTIOC, or FTIOD). When TCNT matches GR, the compare match signal is
generated only after the next TCNT input clock pulse is input.
Figure 13.15 shows an example of the output compare timing.
