AUDIO - Audio indicator
COPY - SCMS copyright indicator
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.
Note: COPY and ORIG will both be set to 1 if the incoming data is flagged as professional, or if the receiver is not
in use.
11.14 Receiver Error (10h) (Read Only)
This register contains the AES3 receiver and PLL status bits. Unmasked bits will go high on occurrence of the error,
and will stay high until the register is read. Reading the register resets all bits to 0, unless the error source is still
true. Bits that are masked off in the receiver error mask register will always be 0 in this register.
QCRC - Q-subcode data CRC error indicator. Updated on Q-subcode block boundaries
CCRC - Channel Status Block Cyclic Redundancy Check bit. Updated on CS block boundaries, valid in Pro mode.
UNLOCK - PLL lock status bit. Updated on CS block boundaries.
V - Received AES3 Validity bit status. Updated on sub-frame boundaries.
CONF - Confidence bit. Updated on sub-frame boundaries.
BIP - Bi-phase error bit. Updated on sub-frame boundaries.
PAR - Parity bit. Updated on sub-frame boundaries.

0
0 - Received data is linearly coded PCM audio
1 - Received data is not linearly coded PCM audio
0 - Copyright asserted
1 - Copyright not asserted
0 - Received data is 1st generation or higher
1 - Received data is original
0 - No error
1 - Error
0 - No error
1 - Error
0 - PLL locked
1 - PLL out of lock
0 - Data is valid and is normally linear coded PCM audio
1 - Data is invalid, or may be valid compressed audio
0 - No error
1 - Confidence error. This is the logical OR of BIP and UNLOCK.
0 - No error
1 - Bi-phase error. This indicates an error in the received bi-phase coding.
0 - No error
1 - Parity error
