This bit goes to “1” when Q-subcode stored in register addresses 13H to 1CH is updated.
This bit goes to “1” when C-bit stored in register addresses 0AH to 0EH changes.
This bit goes to “1” when either the FS3-0 or PEM bit changes.
This bit is made by encoding channel status bits.
This bit outputs an OR’ed result of NPCM and DTSCD bits.
This bit goes to “1” if a parity error or biphase error is detected in the sub-frame.
