Figure 5–43
Because this example does not require the use of the alternate CMU transmitter PLL
or additional transmitter PLLs, the logical channel addressing remains the same as
explained in

Plug-In Manager, the total number of channels in the ALTGX_RECONFIG
MegaWizard Plug-In Manager, and how to connect the ALTGX instances to the
ALTGX_RECONFIG instance.

Four regular transceiver channels in XAUI configuration.
You can configure these channels from the XAUI configuration (the primary
configuration) to the PCIe Gen2 ×4 configuration (the secondary configuration)
and vice versa.
