FIFO Interface Data Structure
29.7.3.4 Aging Task
The task periodically checks the address table for old entries. If an entry is older than a
configurable maximum, the entry is removed from the table.
29.8 FIFO Interface Data Structure
The data structure defined in the following tables for the FIFO interface must be respected
to ensure proper data transmission on the Ethernet Line. Byte 0 is sent and received first
to/from the line.
The size of a Frame on the FIFO interface may not be a modulo of 64-Bit. Together with
the last word of the frame, the valid byte(s) of data is (are) defined by the interface signal
ff_tx_modN(2:0) for transmit and ff_rx_modN(2:0) for receive respectively.
