6.8. Steps to Perform Dynamic Reconfiguration

You can dynamically reconfigure blocks in the transceiver channel or PLL through the
reconfiguration interface.
The following procedure shows the steps required to reconfigure the channel and PLL
blocks.
1. Enable dynamic reconfiguration in the IP.
2. Enable the desired configuration file formats in the IP.
3. Enable the desired dynamic reconfiguration features (such as multiple
reconfiguration profiles, including PMA analog settings in configuration files) or
feature blocks (such as embedded reconfiguration streamer and ADME).
4. If you are using:
• Direct reconfiguration flow—Refer to the register map for feature address and
valid value of write data for the feature.
• IP guided reconfiguration flow—Note the settings of the base configuration and
generate the corresponding configuration files. Note the settings of the
modified configuration and generate the corresponding configuration files. Find
out the differences in settings between the base and modified configurations.
• IP guided reconfiguration flow using multiple profiles—Create and store the
parameter settings between the various configurations or profiles using
configuration files. Find out the differences in settings between the various
configurations or profiles using configuration files.
• IP guided reconfiguration flow using the embedded streamer—Refer to the
control and status register map of the embedded reconfiguration streamer to
stream the desired profile settings.
• Reconfiguration flow for special cases—Refer to the lookup registers to be
accessed for each special case, such as TX PLL switching, TX PLL reference
clock switching, and RX CDR reference clock switching.
5. Place the channels in digital reset either simultaneously or one after another. For
details about placing the channel in reset, refer to "Model 1: Default Model" and
"Model 2: Acknowledgment Model" in the Resetting Transceiver Channels chapter.
If you are reconfiguring:
• PLLs—Place the channel transmitter associated with the PLL in reset (digital).
• TX simplex channels—Place the TX channels being reconfigured in reset
(digital).
• RX simplex channels—Place the RX channels being reconfigured in reset
(digital).
• Duplex channels—Place the channel TX and RX being reconfigured in reset
(digital).
