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.

6.26

Receiver Errors Mask (address 27h)

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
