2. Serial mode
In Serial Mode, INT0/1 pin output the ORed signal among those eight events. However, each events can be masked by
each mask bits. When each bit masks those events, the event does not affect INT0/1 pin operation (those mask do not
affect those resisters (UNLOCK, PAR, etc.) themselves. Once INT0 pin goes “H”, it maintains “H” for 1024/fs cycles
(this value can be changed by EFH0-1 bits) after the all events are removed. Once those PAR, QINT or CINT bit goes
“1”, it holds “1” until reading those registers. While the AK4114 loses lock, the channel status an Q-subcode bits are not
updated and holds the previous data. At initial state, INT0 outputs the ORed signal between UNLOCK and PAR, INT1
outputs the ORed signal among AUTO, DTSCD and AUDION.
