Section 9 16-Bit Free-Running Timer (FRT)
9.5.2
A compare-match signal occurs at the last state when the FRC and OCR values match (at the
timing when the FRC updates the counter value). When a compare-match signal occurs, the level
selected by the OLVL bit in TOCR is output at the output compare pin (FTOA or FTOB). Figure
9.5 shows the timing of this operation for compare-match A.
