Bit 4: Transmit FIFO Aborted Transfer Latched (TFATL) – This bit is set when a transfer is aborted. An aborted
transfer does not occur in UTOPIA mode. In POS-PHY mode, an aborted transfer occurs when a packet error (a
transfer with TERR and TEOP asserted) occurs. An aborted transfer is stored in the transmit FIFO with an abort
indication.
Bit 3: Transmit FIFO Short Transfer Latched (TFSTL) – This bit is set when a "short transfer" is received. In
UTOPIA mode, a "short transfer" occurs when a start of cell (a transfer with TSOC asserted) occurs before the
previous cell transfer has been completed. In POS-PHY mode, a "short transfer" occurs when a start of packet (a
transfer with TSOP asserted) occurs after a previous start of packet, but before an end of packet (a transfer with
TEOP asserted). In UTOPIA mode, the short transfer data is discarded. In POS-PHY mode, a short transfer is
stored in the transmit FIFO with an abort indication.
Bit 2: Transmit FIFO Invalid Transfer Latched (TFITL) – This bit is set when an "invalid transfer" is initiated. In
UTOPIA mode, an "invalid transfer" occurs when additional cell data is transferred after the last transfer of a cell
and before a transfer with TSOC asserted. In POS-PHY mode, an "invalid transfer" occurs when packet data is
transferred after an end of packet, but before a start of packet (this includes another end of packet transfer). The
invalid transfer data is discarded.
Bit 1: Transmit FIFO Underflow Latched (TFUL) – This bit is set when a Transmit FIFO underflow condition
occurs. An underflow condition results in a loss of data.
Bit 0: Transmit FIFO Overflow Latched (TFOL) – This bit is set when a Transmit FIFO overflow condition occurs.
An overflow condition results in a loss of data.
