11.3.6
The output compare flags are set to 1 by an internal compare-match signal generated when the
FRC value matches the OCRA or OCRB value. This compare-match signal is generated at the last
state in which the two values match, just before FRC increments to a new value.
Accordingly, when the FRC and OCR values match, the compare-match signal is not generated
until the next period of the clock source. Figure 11.12 shows the timing of the setting of OCFA
and OCFB.
