Document Table of Contents Interlaken Mode

In Interlaken mode, the TX Core FIFO operates as an elastic buffer. In this mode, you have additional signals to control the data flow into the FIFO. Therefore, the FIFO write clock frequency does not have to be the same as the read clock frequency. You control the writing to the TX Core FIFO with tx_fifo_wr_en by monitoring the FIFO flags. The goal is to prevent the FIFO from becoming full or empty. On the read side, read enable is controlled by the Interlaken frame generator.
