The followings nine events the INT0 and INT1 pins to trigger the interrupt condition. When the PLL is OFF (Clock
Operation Mode 1), INT0 and INT1 pins go to “L”.

Error Handing for RX (PSEL = “0”)
: PLL unlock state detect
: Parity error or bi-phase coding error detection
: Non-Linear PCM or DTS-CD Bit Stream detection
: Validity flag detection
: Non-audio detection
: Sampling frequency or pre-emphasis information change detection
: U-bit Sync flag
: Channel status sync flag
: DAT Start ID detect
correct or when those preambles are not correct.
“1” when the PLL loses lock. The AK4115 loses lock when the time between two preambles is not
“1” when parity error or bi-phase coding error is detected, updated every sub-frame cycle.
The OR function of NPCM and DTSCD bits.is available at the AUTO bit.
“1” when validity flag is detected. Updated every sub-frame cycle.
“1” when the “AUDION” bit in recovered channel status indicates “1”. Updated every block cycle.
When either FS3-0 bit or PEM bit is changed, it maintains “1” during 1 sub-frame.
“1” when the Q-subcode differs from the old one. Updated every sync code cycle for Q-subcode.
“1” when received C bit differs from the old one. Updated every block cycle.
“1” when the category code indicates “DAT” and “DAT Start ID” is detected. When DCNT bit is
“1”, it does not indicate “1” even if “DAT Start ID” is detected again within “3841 x LRCK”.
When “DAT Start ID” is detected again after “3840 x LRCK” passed, it indicates “1”. When
DCNT bit is “0”, it indicates “1” every “DAT Start ID” detection.
