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.
