12.6.2.11 Asynchronous Stream Receive
The Asynchronous streaming receive packet format is shown below. The first quadlet contains dataLength, tag, and Channel number for source
identification, and synchronization information. The following quadlets contain (possibly zero) quadlets of block information. The last quadlet
contains transmission speed and status information. Asynchronous stream packets are placed in the Receive Response FIFO.
NOTE:
12.6.2.12 Self-ID and PHY packets receive
The self-ID and PHY packet receive formats are shown below. The first quadlet contains a synthesized packet header with a tCode of 0xE
(hex). For self-ID information, the remaining quadlets contain data that is received from the time a bus reset ends to the first subaction gap. This
is the concatenation of all the self-ID packets received. Note that the bit-inverted check quadlet is included in the Read Request FIFO and the
application must check it.
The “ackSent” field will either be “ACK_DATA_ERROR” if a non-quadlet-aligned packet is received or there was a data overrun, or
“ACK_COMPLETE” if the entire string of self-ID packets was received.
For PHY packets, there is a single following quadlet which is the first quadlet of the PHY packet. The check quadlet has already been verified
and is not included.
