Section 9 Timers
Output Compare Flag (OCFA or OCFB) Set Timing: OCFA and OCFB are set to 1 by internal
compare match signals that are output when FRC matches OCRA or OCRB. The compare match
signal is generated in the last state during which the values match (when FRC is updated from the
matching value to a new value). When FRC matches OCRA or OCRB, the compare match signal
is not generated until the next counter clock. Figure 9.29 shows the OCFA and OCFB set timing.
Overflow Flag (OVF) Set Timing: OVF is set to 1 when FRC overflows from H'FFFF to H'0000.
Figure 9.30 shows the timing.
