Therefore, 0 data can be transferred ahead of 1 data by making compare match B occur before
compare match A. The 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 TGIA interrupt handling routine write the next data in
NDR, or by having the TGIA interrupt activate the DTC or DMAC. Note, however, that the next
data must be written before the next compare match B occurs.
Figure 11.11 shows the timing of this operation.
