11.5.7
The output compare flag, OCFA or OCFB, is set to 1 by a 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. When the
FRC and OCRA or OCRB value match, the compare-match signal is not generated until the next
cycle of the clock source. Figure 11.12 shows the timing of setting the OCFA or OCFB flag.
11.5.8
The FRC overflow flag (OVF) is set to 1 when FRC overflows (changes from H'FFFF to H'0000).
Figure 11.13 shows the timing of setting the OVF flag.
