13.2.11 Isochronous Receiver Interrupt Acknowledge (IRXINTACK) – Base Address: 0x04C
31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
SV01025
Reset Value 0x00000000
Bit 14:
R/W SYTOVF: SYT FIFO overflow. The isochronous receiver’s SYT field FIFO has overflowed and has been
automatically reset and cleared. This interrupt alerts the host controller that up to 7 AVFSYNC pulses may be
missing due to an SYT field reception error.
Bit 13:
R/W IRO/E: Odd/even key change. Software should write in the new set of keys to the cipher.
Bit 12:
R/W IREMI: This bit indicates when there has been a change in the received EMI bit values (bits 2 and 3 of register
0x054). This interrupt, when = 1, indicates that a changed EMI field has been received.
Bit 10:
R/W IR100LFT: Interrupt when receiver queue reaches 100 quadlets from full.
Bit 9:
R/W IR256LFT: Interrupt when receiver queue reaches 256 quadlets from full.
Bit 8:
R/W IR512LFT: Interrupt when receiver queue reaches 512 quadlets from full. This bit is disabled if 0.5K Byte buffer size
is set.
Bit 7:
R/W IRXFULL: Isochronous data memory bank has become full. this is a fatal error, the recommended action is to reset
and re-initialize the receiver.
Bit 6:
R/W IRXEMPTY: Isochronous data memory bank has become empty.
Bit 5:
R/W FSYNC: Pulse at fsync output.
Bit 4:
R/W SEQERR: Sequence error of data blocks.
Bit 3:
R/W CRCERR: CRC error in bus packet.
Bit 2:
R/W CIPTAGFLT: Faulty CIP header tag (E,F bits). i.e.: The CIP header did not meet the standard and the whole packet
is ignored.
Bit 1:
R/W RCVBP: Bus packet processing complete.
Bit 0:
R/W SQOV: Status queue overflow. This is a fatal error, the recommended action is to reset and re-initialize the receiver.
13.2.12 Isochronous Receiver Interrupt Enable (IRXINTE) – Base Address: 0x050
Interrupt enable bits for AV Receiver.
31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
SV01026
Reset Value 0x00000000
Bit 13..0 are interrupt enable bits for the Isochronous Receiver Interrupt Acknowledge (IRXINTACK).
