14.11 Receiver Channel Status (0Ah)

The bits in this register can be associated with either channel A or B of the received data. The desired chan-

nel is selected with the CHS bit of the Control1 register.

AUX3:0

- Incoming auxiliary data field width, as indicated by the incoming channel status bits, decoded ac-

cording to IEC60958 and AES3.

0000 - Auxiliary data is not present.

0001 - Auxiliary data is 1 bit long.

0010 - Auxiliary data is 2 bits long.

0011 - Auxiliary data is 3 bits long.

0100 - Auxiliary data is 4 bits long.

0101 - Auxiliary data is 5 bits long.

0110 - Auxiliary data is 6 bits long.

0111 - Auxiliary data is 7 bits long.

1000 - Auxiliary data is 8 bits long.

1001 - 1111 Reserved

PRO

- Channel status block format indicator

0 - Received channel status block is in the consumer format.

1 - Received channel status block is in the professional format.

COPY

- SCMS copyright indicator

0 - Copyright asserted.

1 - Copyright not asserted. If the category code is set to General in the incoming AES3 stream, copyright

will always be indicated by COPY, even when the stream indicates no copyright.

ORIG

- SCMS generation indicator, decoded from the category code and the L bit.

0 - Received data is 1st generation or higher.

1 - Received data is original.

Note:

COPY

and ORIG will both be set to 1 if incoming data is flagged as professional or if the receiver

is not in use.

EMPH

– Indicates whether the input audio data has been pre-emphasized. Also indicates turning on of the

de-emphasis filter during de-emphasis auto-select mode.

0 – 50

μs/15 μs pre-emphasis indicated.

1 – 50

μs/15 μs pre-emphasis not indicated.

PCM, DTS_LD, DTS_CD and IEC61937 are mutually exclusive. A ‘1’ indicated the condition

was detected.

PCM

– Uncompressed PCM data was detected.

IEC61937

– IEC61937 data was detected.
