Document Table of Contents TX FIFO Register Mode

The register mode bypasses the FIFO functionality to eliminate the FIFO latency uncertainty for applications with stringent latency requirements. This is accomplished by tying the read clock of the FIFO with its write clock. The register mode incurs only one clock cycle of latency when interfacing to the FPGA fabric.
