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
The time it takes for data to travel from the Input
pin through the IFF latch to the I output with no
input delay programmed
