ZHCSIM2D June 2010 – August 2021 PCM9211
PRODUCTION DATA
The PCM9211 can also detect Non-PCM data (AC-3, DTS-CD, and so forth) using one of these two methods:
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.
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 Section 7.3.8.8 section of this document. The error signal can be monitored from either the ERR_INT0 pin or the NPCM_INT1 pin.
