• Description: 96 kHz DIGITAL AUDIO INTERFACE RECEIVER
• Manufacturer: CIRRUS [Cirrus Logic]

Note:
8.12
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.
8.13
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,

QCRC
1 - Received data is original
1 - Error
1 - Error
1 - PLL out of lock
1 - Data is invalid, or may be valid compressed audio
1 - Confidence error. This is the logical OR of BIP and UNLOCK.
1 - Bi-phase error. This indicates an error in the received bi-phase coding.
1 - Parity error
0 - Received data is 1st generation or higher
0 - No error
0 - No error
0 - PLL locked
0 - Data is valid and is normally linear coded PCM audio
0 - No error
0 - No error
0 - No error
