DTS_CD

– DTS_CD data was detected.

Reserved

– This bit may change state depending on the input audio data.

DGTL_SIL

– Digital Silence was detected: at least 2047 consecutive constant samples of the same 24-bit

audio data on both channels.

96KHZ

– If the input sample rate is

≤ 48 kHz, outputs a “0”. Outputs a “1” if the sample rate is ≥ 88.1 kHz.

Otherwise the output is indeterminate.

14.13 Receiver Error (0Ch)

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

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.

- 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. The logical OR of UNLOCK and BIP. The input data stream may be near error condi-

tion due to jitter degradation.

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.
