The AK4115 can control and monitor block start, channel status bits, user bits and validity bit for RX and TX. B, C and
U pins are bi-directional and the direction of input/output can be selected by the BCU_IO bit. B, C, U and VOUT pins
become “L” (BCU_IO bit = “1”) in an unlocked state of Mode 2.
a. Serial mode & Except AES3 mode (P/SN pin = “L”, AES3 bit = “0”)
Note 23. Channel status bit for RX can be monitored by both C pin and CR191-0 bits.
Note 24. Validity bit for RX can be monitored by both VOUT pin and VRX bit.
Note 25. C pin and CT191-0 bits are ORed internally.
Note 26. VIN pin and VTX bit are ORed internally.
Note 27. When UDIT bit is “1”, the recovered U bits are used for DIT(DIR-DIT loop mode of U bit).
