CS42526_05 Datasheet, PDF (69/93 Pages) Cirrus Logic – 114 dB, 192 kHz 6-Ch Codec with S/PDIF Receiver

6.25.3 PLL LOCK STATUS (UNLOCK)
Default = x
0 - PLL locked
1 - PLL out of lock
Function:
Indicates the lock status of the PLL.

6.25.4 RECEIVED VALIDITY (V)
Default = x
0 - Data is valid and is normally linear coded PCM audio
1 - Data is invalid, or may be valid compressed audio
Function:
Indicates the received validity status. This bit is updated on sub-frame boundaries.
6.25.5 RECEIVED CONFIDENCE (CONF)
Default = x
0 - No error
1 - Confidence error. The logical OR of UNLOCK and BIP. The input data stream may be near an error
condition due to jitter.
Function:
Indicates the received confidence status. This bit is updated on sub-frame boundaries.
6.25.6 BI-PHASE ERROR (BIP)
Default = x
0 - No error
1 - Bi-phase error. This indicates an error in the received bi-phase coding.
Function:
Indicates a bi-phase coding error. This bit is updated on sub-frame boundaries.
6.25.7 PARITY STATUS (PAR)
Default = x
0 - No error
1 - Parity Error
Function:
Indicates the Parity status. This bit is updated on sub-frame boundaries.

Default = 00000000
Function:
The bits in this register serve as masks for the corresponding bits of the Receiver Errors register. If a
mask bit is set to 1, the error is unmasked, meaning that its occurrence will appear in the receiver
errors register, will affect the RERR interrupt, and will affect the current audio sample according to
