The second case uses bidirectional IODELAY when the I/O is an input switching to an
output.
by the 3-state TSCONTROL signal coming from the ODDR T flip-flop. This controls the
selection of MUXes E and F for the output path and ODELAY_VALUE respectively.
Additionally, the OBUF changes to not being 3-stated and starts to drive the PAD.
