10. Programmable Timing Pattern Controller (TPC)
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. The next data must be written before the next compare match B occurs.
Figure 10.10 shows the timing relationships.
