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

pin through the IFF latch to the I output with no
input delay programmed
