Notes:
• A corresponding interrupt can be enabled for AVLINK_TX_READY_RAW by setting the
mask AVLINK_TX_READY_MB1 (IO Map, Address 0x50[7]) or
AVLINK_TX_READY_MB2 (IO Map, Address 0x4F[3]). Refer to Section
information on the interrupt feature.
• A corresponding interrupt can be enabled for AVLINK_TX_ARBITRATION_LOST_RAW

Rev. F August 2010
Description
Last outgoing message failed to be transmitted or/and the AV.link
transmit section is not ready yet to transmit a new message
Last message in transmitter buffer was transmitted successfully and
transmit module is ready to accept and transmit next message
Description
No arbitration lost during transmission of last message.
More than one AV.link initiator, including AV.link transmitter itself, that
wants to transmit a message on AV.link bus at the same time; and the
AV.link transmit has lost the arbitration to a second initiator. When this
bit is set, transmit section stops transmitting and becomes a follower.
Description
Transmission time-out during transmission of last message.
Transmit section tried transmitting last message up to number of times
indicated by AVL_TX_RETRY register, but message was not transmitted
successfully.
Reason for failure either due to a no acknowledge flagged by the follower
or because a low drive occurred on the AV.link bus.
AVL_TX_NACK_COUNTER register stores a value corresponding to
number of times transmission failed because of lack of acknowledge by
the follower. The AVL_TX_LOWDRIVE_COUNTER register stores a
value corresponding to the number of times the transmission failed
because of a low drive.
