NOTE
In the above figure, NAND_CS can be either CS0 or CS1
depending on the boot location. It is set using SW5[6].
If connecting NAND flash to CS0, set SW5[6] to OFF, and connect RY/BY_N signal to
IFC_RB0_N. If connecting NAND flash to CS1, set SW5[6] to ON, and connect RY/
BY_N signal to IFC_RB1_N.
4.3 SerDes
On the C29x PCIe card, the SerDes module implements link serialization/deserialization
and PCS functions for a PCI express link, operating at 2.5 or 5 Gbaud.
The table below shows the different settings for SerDes.
