17.9.3.5.2
The single output compare operation is selected by writing to only one of the two data registers (A or B),
thus enabling only one of the comparators. Following the first successful match on the enabled channel,
the output level is fixed and remains at the same level indefinitely with no further software intervention
being required. To generate a single output compare, the OCAB mode should be used to generate a flag on
both the A and the B match.
