Logical Channel Addressing of PMA-Only Channels
CMU channels are always PMA-only channels. The regular transceiver channels can
be optionally configured as PMA-only channels.
Set the starting channel number for the PMA-only channels in the What is the
starting channel number? option in the ALTGX MegaWizard Plug-In Manager.
For a single ALTGX instance connected to the dynamic reconfiguration controller, set
the starting channel number to 0. The logical channel address of the first channel in
the ALTGX instance is 0. The logical channel addresses of the PMA-only channels
within the same ALTGX instance increment in multiples of four (unlike the logical
channel addressing of regular transceiver channels that are not configured in Basic
[PMA Direct] functional mode, where the logical channel address increments in steps
of one within the same ALTGX instance).
For multiple ALTGX instances connected to the dynamic reconfiguration controller,
set the starting channel number of the first instance to 0. You must set the next
multiple of four as the starting channel number for the remaining ALTGX instances.

instances controlled by a single dynamic reconfiguration controller, where both
ALTGX instances have PMA-only channels. For more information about the What is
the number of channels controlled by the reconfig controller? option, refer to
Number of Channels Option in the ALTGX_RECONFIG Instance” on page
When PMA-only channel reconfiguration involves a transmitter PLL, you also must
account for the logical channel address of the PLL used. If there are four channels in
Basic [PMA Direct] ×N functional mode, each channel requires a logical channel
address (0, 4, 8, 12), and the transmitter PLL used requires an address (16).
