This is further classified into initialized and run-time configured modes.
Run-time Configured Non-5G New Radio Mode
In this mode the core is configured at run-time using the AXI4-Lite parameter interface and the AXI4-Stream control interface for either turbo decode or LDPC encode or decode.
Initialized Non-5G New Radio Mode
In this mode the core support logic generates initialization and configuration parameters at start up from the options set in the Vivado® IDE for either turbo decode or LDPC encode or decode. In this mode and for LDPC, do not write LDPC code and shared LDPC code parameters using the AXI4-Lite parameter interface because any write can overwrite the initialized codes and make the behavior unpredictable.
