Figure 22. PHY Packet Receive Format
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.
12.5.2.5
After a packet from one of the queues has been transmitted, the asynchronous transmitter assembles a confirmation (see Figure 23) which is
used to confirm the result of the transmission to the higher layers. Separate confirmations are assembled for request and response
transmissions. Request confirmations are written into the receiver request queue and response confirmations are written into the receiver
response queue.

DESCRIPTION
0
Non-broadcast packet transmitted; addressed node returned no acknowledge (transaction complete).
1
Broadcast packet transmitted or non-broadcast packet transmitted; addressed node returned an acknowledge complete
(transaction complete).
Non-broadcast packet transmitted; addressed node returned an acknowledge pending.
2
4
Retry limit exceeded; destination node hasn’t accepted the non-broadcast packet within the maximum number of retries
(transaction complete).
Acknowledge data error received (transaction complete).
D
16
E
16
Acknowledge type error received (transaction complete).
NOTE:
1. All other codes are reserved.
For every packet written in a transmitter queue by the CPU, there will be one confirmation written in the corresponding receiver queue by the AV
layer logic.
