When using IODELAY in bidirectional mode, the turnaround time needs to be considered.
Figure 7-10
that applies to one use of the bidirectional IODELAY functionality.
When DELAY_SRC = IO, MUXE and MUXF dynamically selects ODATAIN or IDATAIN
and ODELAY_VALUE or IDELAY_VALUE inside the IODELAY block.
The following Verilog code segment is used for demonstrating bidirectional IODELAY:
