IOPLID
The numbers in this table are tested using the methodology presented in
Table 8
This propagation time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the data Input. When this is
true, add the appropriate Input adjustment from
and
The time it takes for data to travel
from the Input pin through the IFF
