Run-Time Reconfiguration
The JESD204B IP core supports run-time reconfiguration for the LMF and data rate settings. The design
example only demonstrates the following set of configuration.
To generate the design example with run-time reconfiguration enabled, the LMF and bonding mode
parameters must match the default value listed in the table below.
