12.5.2.4 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.
