Acknowledge codes
Code
Name
Description
0001
ack_complete
The node has successfully accepted the packet. If the packet was a request subaction, the
destination node has successfully completed the transaction and no response subaction shall follow.
0010
ack_pending
The node has successfully accepted the packet. If the packet was a request subaction, a response
subaction will follow at a later time. This code shall not be returned for a response subaction.
0100
ack_busy_X
The packet could not be accepted. The destination transaction layer may accept the packet on a
retry of the subaction.
0101
ack_busy_A
The packet could not be accepted. The destination transaction layer will accept the packet when the
node is not busy during the next occurrence of retry phase A.
0110
ack_busy_B
The packet could not be accepted. The destination transaction layer will accept the packet when the
node is not busy during the next occurrence of retry phase B.
1101
ack_data_error
The node could not accept the block packet because the data field failed the CRC check, or because
the length of the data block payload did not match the length contained in the dataLength field. This
code shall not be returned for any packet that does not have a data block payload.
1110
ack_type_error
A field in the request packet header was set to an unsupported or incorrect value, or an invalid
transaction was attempted (e.g., a write to a read-only address).

This revision of the AV Link will not generate other acknowledge codes, but may receive them from
newer (1394 A) links. In that case, these new values will show up here.
