In Basic mode, the RX FIFO operates as an elastic buffer, where buffer depths can vary. This mode allows driving write and read side of RX FIFO with different clock frequencies. Monitor the FIFO flag to control write and read operations. For RX FIFO, assert rx_enh_read_en signal with rx_fifo_pfull signal going low.
