The encoding of the eTSEC GMII signals in this FIFO mode is shown in
In this mode flow control can control only the decision to continue transmitting packets, as packet transfers
cannot be suspended once started.
15.6.2.4
The encoded packet 8-bit FIFO mode uses the signals shown in
four states that can be associated with each beat of data. This mode should be used where invalid bytes can
appear between the start and end of packet. Illustrative timing of the encoded packet FIFO mode is shown
in
The encoding of the eTSEC GMII signals in this FIFO mode is shown in
In this mode flow control can cause an indefinite number of invalid data bytes to be transferred. This is the
only mode in which an empty eTSEC Tx FIFO also causes a string of invalid data bytes to be transmitted
rather than causing an underrun error.
