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
Table 5–18
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.
