Non-PCM Data Detection
The PCM9211 can also detect Non-PCM data (AC-3, DTS-CD, etc.) using one of these two methods:
1. Channel Status Bit 1 is '1'.
If Register 28h/CSBIT is set to '1', this function is enabled. Register 39h/SCSBIT1 always indicates Channel
Status Bit 1 status even if CSBIT1 is disabled.
2. A Burst Preamble (P
/P
) is found in the S/PDIF stream.
A
B
If Register 28h/PAPB or Register 28h/DTSCD is set to '1', this function is enabled. If DTS-CD detection is
active, it uses DTSCD, and can also be set in Register 29h/DTS16, 29h/DTS14, and Register
29h/DTSPRD[1:0].
If the PCM9211 detects a Burst Preamble when Non-PCM detection is enabled, an error signal and BPSYNC
signal are generated. The BPSYNC signal can be monitored through MPIO_A/MPIO_B/MPIO_C. For more
details, see the
MPIO
section of this document. The error signal can be monitored from either the ERR_INT0 pin
or the NPCM_INT1 pin.

The following sequence is an example of reading P
function.
1. Set Register 2Ah/MPCRNW0 to '0'.
2. Check that Register 2Ch/OPCRNW0 is '1'.
3. Read the P
