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

channel 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, de-

coded according 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 consumer format

1 - Received channel status block is in 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, copy-

right 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 – 50us/15us pre-emphasis indicated
