CS8415A
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 the incoming data is flagged as professional, or if the receiver is not
in use.

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. This register defaults
to 00h.
QCRC - Q-subcode data CRC error indicator. Updated on Q-subcode block boundaries
0 - No error
1 - Error
CCRC - Channel Status Block Cyclic Redundancy Check bit. Updated on CS block boundaries,
valid in Pro mode
0 - No error
1 - Error
UNLOCK - PLL lock status bit. Updated on CS block boundaries.
0 - PLL locked
1 - PLL out of lock
V - Received AES3 Validity bit status. Updated on sub-frame boundaries.
0 - Data is valid and is normally linear coded PCM audio
1 - Data is invalid, or may be valid compressed audio
CONF - Confidence bit. Updated on sub-frame boundaries.
0 - No error
1 - Confidence error. This is the logical OR of BIP and UNLOCK.
BIP - Bi-phase error bit. Updated on sub-frame boundaries.
0 - No error
1 - Bi-phase error. This indicates an error in the received bi-phase coding.
PAR - Parity bit. Updated on sub-frame boundaries.
0 - No error
1 - Parity error

The bits in this register serve as masks for the corresponding bits of the Receiver Error Register. If a mask bit is set
to 1, the error is unmasked, meaning that its occurrence will appear in the receiver error register, will affect the RERR
pin, will affect the RERR interrupt, and will affect the current audio sample according to the status of the HOLD bit.
If a mask bit is set to 0, the error is masked, meaning that its occurrence will not appear in the receiver error register,
