Contention between OCR Write and Compare-Match: If a compare-match occurs during the
state after an OCRA or OCRB write cycle, the write takes priority and the compare-match signal
is inhibited.
Figure 11.20 shows this type of contention.
If automatic addition of OCRAR/OCRAF to OCRA is selected, and a compare-match occurs in
the cycle following the OCRA, OCRAR and OCRAF write cycle, the OCRA, OCRAR and
OCRAF write takes priority and the compare-match signal is inhibited. Consequently, the result of
the automatic addition is not written to OCRA.
Figure 11.21 shows this timing
