See Table 2.
dataLength
The number of bytes of data to be transmitted in this packet
extendedTcode
The tCode indicates a lock transaction, this specifies the actual lock action to be
performed with the data in this packet.
block data
The data to be sent. If dataLength=0, no data should be written into the FIFO for
this field. Regardless of the destination or source alignment of the data, the first
byte of the block must appear in the high order byte of the first quadlet.
padding
If the dataLength mod 4 is not zero, then zero–value bytes are added onto the end
of the packet to guarantee that a whole number of quadlets is sent.
12.5.1.4
The unformatted transmit format is shown in Figure 11. The first quadlet contains packet control information. The remaining quadlets contain
data that is transmitted without any formatting on the bus. No CRC is appended on the packet, nor is any data in the first quadlet sent. This is
used to send PHY configuration and Link-on packets. Note that the bit-inverted check quadlet must be included in the FIFO since the AV Link
core will not generate it.
