13.2.4
The AV Transmitter Interrupt Control and Status register is the interrupt register for the AV transmitter.
Isochronous Transmitter Interrupt Acknowledge (ITXINTACK) – Base Address: 0x02C
Bits 2, 3, and 4 ”auto repair” themselves, i.e. AVLINK will detect the situation and attempt to recover on its own. The host controller still needs to
clear these interrupts to be alerted the next time.

Bits 6 .. 0 are interrupt acknowledge bits; and are defined as:
R/W
TRMSYT: Interrupt on transmission of a SYT in CIP header quadlet 2
R/W
TRMBP: Interrupt on payload transmission/discard complete.
R/W
DBCERR: Acknowledge interrupt on Data Block Count (DBC) synchronization loss.
R/W
INPERR: Acknowledge interrupt on input error (input data discarded).
R/W
DISCARD: Interrupt on lost cycle (payload discarded).
R/W
ITXFULL: Interrupt on isochronous memory bank full. This is a fatal error, the recommended action is to reset and
re-initialize the transmitter.
R/W
ITXEMPTY: Interrupt on isochronous memory bank empty.
Other bits will always read ‘0’.
