of the transceivers without powering down any part of the device. This chapter
describes and provides examples about the different modes available for dynamic
reconfiguration.
You can use the ALTGX_RECONFIG and ALTPLL_RECONFIG controller instance to
reconfigure the physical medium attachment (PMA) controls, physical coding
sublayer (PCS), multipurpose phase locked loops (PLLs), and general purpose PLLs.

Used whenever the concept of logical channel addressing is explained. This term does not refer
to the logical_channel_address port available in the ALTGX_RECONFIG MegaWizard
Plug-In Manager.
A file with the .mif extension will be generated for .mif-based reconfiguration mode. It can be
either in Channel Reconfiguration mode or PLL Reconfiguration mode.

lists the terms used in this chapter:
Channel Reconfiguration mode—this file contains information about the various ALTGX
MegaWizard Plug-In Manager options that you set. Each word in the .mif is 16 bits wide.
The dynamic reconfiguration controller writes information from the .mif into the
transceiver channel.
PLL Reconfiguration mode—this file contains information about the various PLL
parameters and settings that you use to configure the transceiver PLL to different output
frequency. The .mif file is 144  1-bit size. During PLL reconfiguration mode, the PLL
reconfiguration controller shifts these 144-bit serially into the transceiver PLL.
