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.
AUDION: Audio Bit Output
0: Audio
1: Non Audio
This bit is made by encoding channel status bits.
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.
VRX: Validity of channel status for RX
0: Valid
1: Invalid
UNLCK: PLL Lock Status
0: Lock
1: Unlock
CINT: Channel Status Buffer Interrupt
0: No change
1: Changed
This bit goes to “1” when C-bit stored in register addresses 0CH to 24H changes.
AUTO: Non-PCM Auto Detect
0: No detect
1: Detect
QINT: Q-subcode Buffer Interrupt
0: No change
1: Changed
This bit goes to “1” when Q-subcode stored in register addresses 40H to 49H changes.
STC, QINT, CINT and PAR bits are initialized when 07H is read.
