input delay adjustments, output delays terminating at pads
(based on standard) and 3-state delays.
T
input buffer to the I-pin of an IOB pad. The delay varies
depending on the capability of the SelectIO input buffer.
T
pad through the output buffer of an IOB pad. The delay
varies depending on the capability of the SelectIO output
buffer.

T
pad through the output buffer of an IOB pad, when 3-state is
disabled. The delay varies depending on the SelectIO
capability of the output buffer.
Table 39
described as the delay from the T pin to the IOB pad
through the output buffer of an IOB pad, when 3-state is
enabled (i.e., a high impedance state).
IOTP
is described as the delay from the T pin to the IOB
