Hi,


For your information, the width of tx_parallel_data and tx_control depends on whether the simplified interface is enabled or not. If the simplified interface is enabled, then tx_parallel_data = 64 bits and tx_control = 3 bits. The value 2'b01 indicates a data word and the value 2'b10 indicates a control word.


Best regards,
