CHANNEL STATUS OUTPUT

DATA CATEGORY SPECIFICATION BIT 1 OUTPUT ( AUDIO )

The AUDIO pin outputs bit 1 of the channel status indicating that the input bi-phase data is PCM

audio data. AUDIO status is immediately output upon detection of RERR even during High output.

An output ORed with IEC61937 or the DTS-CD/LD detection flag is also possible with AOSEL.

AUDIO

OUTPUT CONDITIONS

PCM audio data (CS bit 1 = Low)

Non-audio data (CS bit 1 = High
