QINT: Q-subcode Buffer Interrupt
0 : No change
1 : Changed
This bit goes to “1” when Q-subcode stored in register addresses 13H to 1CH is updated.
CINT: Channel Status Buffer Interrupt
0 : No change
1 : Changed
This bit goes to “1” when C-bit stored in register addresses 0AH to 0EH changes.
STC:
Sampling Frequency or Pre-emphasis Information Change Detection
0 : No detect
1 : Detect
This bit goes to “1” when either the FS3-0 or PEM bit changes.
AUDN:
Audio Bit Output
0 : Audio
1 : Non audio
This bit is made by encoding channel status bits.
V: Validity Bit
0 : Valid
1 : Invalid
AUTO:
Non-PCM or DTS-CD Bit Steam Auto Detection
0 : No detect
1 : Detect
This bit outputs the OR’ed value of NPCM and DTSCD bits.
PAR:
Parity Error or Bi-phase Error Status
0 : No error
1 : Error
This bit goes to “1” if a parity error or biphase error is detected in the sub-frame.
UNLCK: PLL Lock Status
0 : Lock
1 : Unlock
QINT, CINT and STC bits are initialized when 07H is read.
