IOB Output Switching Characteristics,
Output delays terminating at a pad are specified for LVTTL with 12 mA drive and fast slew rate. For other standards, adjust
the delays with the values shown in
DS025-3 (v2.2) July 17, 2002

SR input to valid data on Pad (asynchronous)
GSR to Pad
A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values can not be guaranteed “best-case”, but
if a “0” is listed, there is no positive hold time.
3-state turn-off delays should not be adjusted.
