‘logical_channel_
address’ port for

reconfiguration
This option is applicable only for Analog controls
reconfiguration and is available for selection when the

port is selected by the ALTGX_RECONFIG MegaWizard
Plug-In Manager depending on the number of channels
controlled by the dynamic reconfiguration controller. The
maximum width of the logical_channel_address
port is 9 bits.
