Notes to Figure 2–4:
(1) These ports assume that the dynamic reconfiguration controller is connected to a single channel in the design.
(2) These are the optional PMA control input signals and the optional PMA control output status signals. You must select at least one of these PMA
control ports if you want to dynamically configure the PMA controls of a transceiver channel. For a detailed description of all the inputs and outputs
of the ALTGX_RECONFIG instance, refer to “Dynamic Reconfiguration Controller Port List” on page 2–11.
(3) The logical_channel_address port is available for selection only when the number of channels controlled by the dynamic reconfiguration
controller is more than one. The port is shown here to represent the complete port list.
