using the 8-bit FIFO interface.
The 8-bit FIFO interface has 25 signals (including the flow control signals). Illustrative timing of the
GMII-style FIFO mode is shown in

The flow control signals (TSEC n _CRS and TSEC n _COL) are common to all of the FIFO modes.
8-Bit GMII-Style Packet FIFO Mode
TSEC n _CRS becomes an output signal in FIFO modes only.
