7.2.12 Transmit Consume Index Register (TxConsumeIndex - 0xFFE0 012C)
7.2.13 Transmit Status Vector 0 Register (TSV0 - 0xFFE0 0158)
The Transmit Consume Index register (TxConsumeIndex) is a Read Only register with an
address of 0xFFE0 012C. Its bit definition is shown in
Table 217. Transmit Consume Index register (TxConsumeIndex - address 0xFFE0 012C) bit
The transmit consume index register defines the descriptor that is going to be transmitted
next by the hardware transmit process. After a frame has been transmitted hardware
increments the index, wrapping the value to 0 once the value of TxDescriptorNumber has
been reached. If the TxConsumeIndex equals TxProduceIndex the descriptor array is
empty and the transmit channel will stop transmitting until software produces new
descriptors.
The Transmit Status Vector 0 register (TSV0) is a Read Only register with an address of
0xFFE0 0158. The transmit status vector registers store the most recent transmit status
returned by the MAC. Since the status vector consists of more than 4 bytes, status is
distributed over two registers TSV0 and TSV1. These registers are provided for debug
purposes, because the communication between driver software and the Ethernet block
takes place primarily through the frame descriptors. The status register contents are valid
as long as the internal status of the MAC is valid and should typically only be read when
the transmit and receive processes are halted.

Unused
Function
The attached CRC in the packet did not match the
internally generated CRC.
Indicates the frame length field does not match the actual
number of data items and is not a type field.
Indicates that frame type/length field was larger than
1500 bytes.
Transmission of packet was completed.
Packet’s destination was a multicast address.
Packet’s destination was a broadcast address.
Packet was deferred for at least one attempt, but less than
an excessive defer.
Packet was deferred in excess of 6071 nibble times in
100 Mbps or 24287 bit times in 10 Mbps mode.
Packet was aborted due to exceeding of maximum allowed
number of collisions.
Collision occurred beyond collision window, 512 bit times.
