Document Table of Contents RX Data Bitslip

The RX data bit slip in the RX gearbox allows you to slip the recovered data. An asynchronous active high edge on the rx_bitslip port changes the word boundary, shifting rx_parallel_data one bit at a time. Use the rx_bitslip port with its own word aligning logic. Assert the rx_bitslip signal for at least two parallel clock cycles to allow synchronization. You can verify the word alignment by monitoring rx_parallel_data. Using the RX data bit slip feature is optional.
