Therefore, 0 data can be transferred ahead of 1 data by making compare match B occur before
compare match A. NDR contents should not be altered during the interval from compare match B
to compare match A (the non-overlap margin).
This can be accomplished by having the IMFA interrupt service routine write the next data in
NDR, or by having the IMFA interrupt activate the DMAC. The next data must be written before
the next compare match B occurs.
Figure 11.10 shows the timing relationships.
